INCORPORATION BY REFERENCE All publications and patent applications mentioned in this specification are specifically and independently indicated in this application as if each individual publication or patent application was incorporated by reference. The entirety of which is incorporated herein by reference.

  Described herein can communicate with users and others, for example, direct (user selection) input and indirect (users to detect signals from users (eg, from clothes based on wearable electrical devices) A wearable device (eg, “garments”) that can receive both (monitoring) inputs and store or transmit this information. In particular, described herein is a wearable monitoring and input system that can monitor physiological parameters from the wearer.

  Over the last 20 years, the development of mobile telecommunications devices has dramatically expanded and changed the way people communicate. Computers with unprecedented speed computer processors have enabled faster communication with increased processing speed and improved analysis of large amounts of data. Furthermore, sensor technology is also rapidly expanding the way in which patients, even those without expertise, monitor patients. The development of various sensors has made it possible for computers to perform various measurements and analyze them to generate useful information. In recent years, combined use of medical sensing technology with various communication platforms, to monitor people, including patients, or to monitor themselves and communicate the monitoring results to a doctor or caregiver There are new and interesting ways to do this. For example, mobile devices such as smartphones allow mobile device users to communicate remotely and provide some ability to acquire, analyze, use and control information and data. For example, users of mobile devices may use application software (“apps”) for various individualized tasks, such as recording their medical history in a predetermined format, playing games, reading books, and the like. )) May be available. The app can provide information desired by the user in conjunction with a sensor in the mobile device. For example, the app can determine the distance walked and the calories burned during walking in conjunction with an accelerometer in the smartphone.

  The use of a mobile communication platform, such as a smartphone having one or more biometric sensors as described above, has been described in various contexts. For example, Patent Document 1 by Roschk et al. Describes “Device for Monitoring Physical Fitness”, which includes a heart rate monitoring component for detecting heart rate data, An evaluation device for providing fitness information, said information being able to be displayed by a display device and drawn by a processing unit embodied for reading and including supplemental personal data. Patent Document 2 of Nisilia describes “Electronic Device, Arrangement, and Method of Estimating Fluid Loss” that estimates fluid loss, which is “skin temperature data generated by a measurement unit”. And an electrical device comprising a processing unit configured to receive performance data from the measurement unit and to determine a theoretical fluid loss value based on the received performance data.

  Similarly, garments including sensors have been proposed in the past. See, for example, Glaser et al. U.S. Patent No. 6,057,049 describes a "modular microminiature electrical system" designed for use with wearable electronic devices. Deblock et al., U.S. Pat. No. 6,057,049, describes an interconnection and termination method for textiles, which includes “a conductive layer including a conductor includes a terminal and a base provided separately from the terminal. The terminal includes a description that “the terminal has a joining end and an installation end”. Jung et al., U.S. Patent No. 6,057,049, describes a method and apparatus for the integration of electronic equipment into textiles.

  For example, other health-related problems, including cardiovascular problems and respiratory problems, can be detected by monitoring the patient. Monitoring can enable early and effective intervention and provide medical assistance based on the physiological characteristics being monitored before a particular health problem becomes serious. Unfortunately, most currently available cardiovascular and other types of health monitoring systems are cumbersome and inconvenient (eg, not practical to use every day) and are particularly inconspicuous As such, it is difficult or impractical to use for long-term monitoring.

  It has been proposed that patient health parameters, including vital signs (ECG, respiration, blood oxygen concentration, heart rate, etc.) can be actively monitored using one or more wearable monitors. Has been found to date to be difficult to use and relatively inaccurate. Ideally, the subject can wear such a monitor inconspicuously (eg as part of clothing, jewelry, etc.). Although such garments have been proposed, for example, with reference to US Pat. No. 6,057,059, these garments have a number of disadvantages including being uncomfortable, difficult to use, and resulting in inaccurate results. . For example, in an application such as Patent Document 6, a large number of independent electrodes are positioned on a garment and connected to a processor by a woven conductive fiber or the like. Such garments “need consistent and strong conductive contact with the subject's skin” to provide accurate readings, but such designs are such garments that contact these skin areas. It is necessary to limit the clothes to prevent movement of (and the accompanying sensors). Such a configuration can quickly become uncomfortable, especially in garments that are ideal to be worn for hours or even days. Even garments that are worn snugly may move (eg, slip or slide up) relative to the wearer. Furthermore, devices / garments such as those described in the prior art are difficult and expensive to manufacture and can be quite “brittle”, which prevents rough use and washing. Finally, such devices / garments typically cannot handle direct manual user input to the garment, rely on completely passive monitoring, or (interfaces not on the garment). Some sort of interface is required.

  Garments that include one or more sensors capable of sensing biometric data are not widely used. This may be due in part to the fact that such garments may be limited in the type and variety of inputs they receive and in garment comfort and form factors. For example, the sensor and the wires that supply power to the sensor and receive signals from the sensor are completely integrated into the garment in such a way that the garment can be flexible, attractive, practical and particularly comfortable. It has not been converted. For example, most of such proposed garments do not have sufficient stretch properties. Finally, such proposed garments are also limited in the types of data that the garment can receive and in how the garment processes the received information.

US Published Patent No. 2010/0029598 US Published Patent No. 2009/0157327 US Published Patent No. 2007/0178716 US Published Patent No. 2012/0071039 US Published Patent No. 2005/0029680 US Published Patent No. 2012/0136231

  Thus, existing clothing (eg devices and wearable sensing devices) and processes for analyzing and communicating the physical and emotional state of individuals are inaccurate, inadequate and limited in scope. May be uncomfortable and / or difficult to handle.

  What is needed is a device (including garment) having one or more sensors that can be worn comfortably, but that can provide measurements that are relatively accurate and insensitive to movement over a sustained period of time. It is. It would also be beneficial to provide a garment that can be easily and inexpensively manufactured. Finally, it may be beneficial to provide a garment having a direct user interface on the garment, in particular an interface formed as part of the garment (consisting of fabric).

  What is particularly needed is a stretchable and conductive pattern (eg, traces) that can be deposited or applied onto clothing. These stretchable and conductive patterns can be used with any of the most stretchable fabrics (compressed fabric / compressed clothing, etc.), and together with the underlying fabric, a plurality of conductances can be used without breaking. Can be exercised through multiple stretch / relaxation cycles while maintaining a stable set of electrical properties over time and over multiple uses. Apparatuses and systems including wearable devices (eg, clothes) described herein can address some or all of the issues identified above.

  Described herein is for monitoring physiological parameters having a sensor formed of printed conductive ink on a compressed garment arranged and configured for robust sensing and comfortable wearing. It is clothes. In particular, the garments described herein (eg, shirts, pants, underwear) are configured to enable robust sensing of one or more physiological parameters using a conductive ink sensor, and the conductive The ink sensor is printed directly on the garment and connected to the garment interface area by conductive traces (which may or may not be reinforced on the garment), the interface area being recorded on one or more recorded It may be connected to an analysis unit, such as a microprocessor, configured to measure, store, process and / or transmit parameters.

  For example, described herein is a shirt adapted to continuously monitor a wearer's local breathing. A shirt for monitoring breathing: a shirt body made of fabric, wherein the body is configured as a compression garment that stretches and contracts to hold the shirt against the wearer's torso; A plurality of respiration sensors disposed in different regions of the body, each respiration sensor being printed and / or deposited on an outer portion of the body and a plurality of generally parallel conductive ink traces and A respiratory sensor comprising: a conductive elastic material; and a locally conductive connector, wherein the generally parallel conductive ink traces connect to the locally conductive connector; and An interface (eg, a module interface) disposed on the body, wherein the locally conductive connector for each respiration sensor is connected to the interface , Further the interface, in order to detect the electrical resistance from each said conductive connector, configured to connect to a processor (e.g., the sensor manager unit) may include an interface. Described herein are two types of respiration sensors. Described herein are two types of respiration sensors. The first type is formed of conductive ink traces that can be printed on the fabric forming the garment or transferred and / or attached to the garment. Use any of the conductive ink materials described herein, including in particular those formed by a layer of adhesive and one or more layers of conductive ink with intermediate / gradient regions in between You can do it. The second type of respiration sensor is formed of a conductive elastic material, which will be described in more detail below. Although using one type of respiration sensor may have certain benefits compared to the other (eg, relatively low electrical hysteresis), except where revealed by a particular context, It may be used interchangeably with the other.

In general, the respiration sensor may be local. Different sensors (eg quadrants) of the shirt body can be covered by different sensors, thereby detecting and monitoring “local” breathing. As the wearer tries to breathe and the shirt (which fits the body) stretches and contracts, local breathing may occur due to variations in the resistance of the conductive ink traces and / or the conductive elastic material in each of the different regions. (Movement) is detected. The plurality of generally parallel conductive ink traces includes 3 to 50 parallel traces. A plurality (e.g. 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35, etc. By providing conductive ink traces approximately parallel across the shirt body area, sensing by the respiration sensor can be particularly robust. Each of these parallel traces is connected (in parallel) to the local conductive connector (and connected at the other end to a reference, eg, a reference line), and the overall resistance is effectively determined from the parallel resistance. . For example, R _total = (product of all resistances for each trace) / (sum of each resistance for each trace).

  In some variations, the shirt is configured to detect breathing in four regions (eg, anterior / posterior and chest / abdominal region; or chest / abdomen and left / right region). In some variations, the respiration sensor comprises 8 respiration sensors and senses 8 regions (anterior / rear, chest / abdomen and left / right regions). In general, a plurality of respiration sensors may be separately disposed in the front or back, upper or lower, right or left region of the body. Nine or more regions can be determined (eg, by further dividing the body into smaller compartments) and these regions need not be the same size.

  Each of the plurality of generally parallel conductive ink traces is a stretchable trace, and the stretch of conductive ink typically changes resistance (detects stretch and thereby detects respiration). The plurality of generally parallel conductive ink traces may be printed in any pattern on the outer portion of the body. For example, the traces may be printed as parallel straight lines, zigzag lines, curves, for example, the traces may be printed in a wavy pattern. In general, a plurality of generally parallel conductive ink traces may be configured to generate an electrical resistance that varies through the traces as the subject breathes, for example, the line may be the patient's body when the shirt is worn. May extend in a direction crossing (crossing the chest).

  As described above, a plurality of respiration sensors have a reference line to which each of the generally parallel conductive ink traces is connected at the end of the generally parallel conductive ink trace opposite the local conductive connector. You may be prepared. The reference line may be “ground”. This reference line typically also connects to the interface (and ultimately to the processor that detects the change in resistance of the line due to respiration).

  Each respiration sensor may be configured to average the variable electrical resistance in the plurality of generally parallel conductive ink traces that form the respiration sensor. Thus, by applying a very small current or voltage across the conductive trace, the change in resistance due to respiration can be determined. The conductive traces may generally be insulated (eg, preventing direct contact with the wearer's skin and / or shorting due to sweat, etc.).

  Any of the shirts described herein may also include user input, such as a touchpoint sensor at a touchpoint location on the body, that senses when the wearer touches the shirt at the touchpoint location. Composed. The touch point sensor may be used as an input and / or control for the device. For example, the user may “mark” when something happens, such as lack of breathing or other respiratory episodes, or when activity is increasing (eg, when exercising) or decreasing. Or the recording and / or analysis of respiration may be started / stopped / interrupted, and the detected local respiration may be stored, transmitted, processed, etc. Multiple touch point sensors may be used.

  The shirt may also include one or more additional sensors, such as a heart rate sensor. For example, the shirt may include a conductive ink electrode configured to contact the wearer's skin on the inner surface of the body and an electrode conductive connector extending from the conductive ink electrode to the module interface. The electrodes can be used to detect heartbeats and the like. Multiple electrodes may be used (eg, electrode pairs). For example, the conductive ink electrode may be disposed on a shirt sleeve (or a plurality of sleeves).

  The shirt may also include a holder (eg, a pocket) on the body configured to hold the sensor manager unit in connection with the module interface.

  Other sensors that may be used include any other activity / motion sensor (eg, accelerometer). The other sensor may be on the shirt and / or directly connected to a processor or a part thereof that receives signals from the sensor.

  Locally conductive connectors typically include a conductive material on a substrate attached to the body. The substrate can support the conductive material and interface with the garment to electrically connect the conductive ink with the conductive material forming the connector. For example, the substrate can be a polymeric material. In some variations (see, for example, Appendix A), the substrate is Kapton.

  Also described herein is a method for sensing local breathing using a shirt configured as described above. For example, a method for detecting local breathing is arranged in parallel with the step of wearing any of the shirts described herein and different (typically non-overlapping) regions on the body of the shirt. Receiving / transmitting / storing / analyzing resistance variation through a plurality of provided conductive ink traces.

  Also described herein are garments (eg, shirts and / or pants) configured to continuously monitor a wearer's electrocardiogram (ECG). For example, a shirt: a shirt body made of fabric, wherein the body is configured as a compressed garment that stretches and contracts to hold the shirt against the wearer's torso; on the body, the shirt A first set of six electrical sensors arranged in a first curve extending across the left chest region of the wearer's chest when each is worn, A first set of six electrical sensors comprising conductive ink electrodes printed on the inner surface of the body; disposed on a second curve adjacent to the first curve on the body; A second (redundant) set of six electrical sensors; a support harness region of the body extending from the neck region and overlying the first and second sets of electrical sensors; on the inner surface of the body Formed from printed conductive ink A right arm electrode; and a left arm electrode formed from a conductive ink printed on the inner surface of the body, wherein each electrical sensor is on the body by a conductive trace extending from the electrical sensor to the interface. And further configured to connect to a sensor manager unit for detecting electrical activity from the electrical sensor, the right arm electrode, and the left arm electrode, respectively.

  In general, such shirts can provide multiple electrodes on the chest (chest region), which electrodes act as independent leads (eg, V1-V6) for the 12-lead ECG chest electrodes (eg, V1-V6). (In parallel). The device may be configured to robustly detect signals even when there is an electrode shift or movement as the garment moves on the wearer's body. Furthermore, an additional support area on the body of the garment, even when the garment can be comfortably held in place and the wearer's body curvature can prevent good adhesion between the wearer and the electrode. The position of the electrode can be held relatively firmly by (for example, the yoke / harness support).

  Described herein is a support garment configured to be worn over a garment such as a shirt disclosed in the present application. The support garment may include a support structure configured to push the sensor / electrode on the shirt into a relatively good engagement with the wearer's chest. The support structure can be inflatable and can be configured based on the gender of the wearer and the anatomy of the chest. In some cases, the support structure is self-expanding.

  The invention also relates to stretchable conductive traces and methods of making the same. In particular, described herein is a conductive elastic ribbon material that can be used as a respiration sensor and / or as a conductive trace. These conductive elastic ribbons can be formed of these stretchable (eg elastic) materials impregnated with conductive inks that can be dried (at least partially or completely) and can be garmented by gluing, sewing, etc. Can be connected. Unlike other conductive materials, including conductive inks and wires, these conductive elastic ribbons can be repeatedly subjected to mechanical loading and unloading when there is electrical hysteresis But it hardly presents.

  Specific examples of devices of the type described herein (eg, devices and systems that include garments) are printed on compressed garments that are arranged and configured for robust sensing and comfortable wearing. Mention may be made of a physiological parameter monitoring garment having a sensor formed of conductive ink. In particular, the garments described herein (eg, shirts, pants, underwear) are configured to allow robust sensing of one or more physiological parameters using a respiration sensor, the respiration sensor comprising: Directly connected to, transferred onto the garment, or printed directly onto the garment, and connected to the garment interface area by conductive traces (such as wire ribbon material, which may or may not be reinforced on the garment) The interface area can be connected to an analysis unit, such as a microprocessor, configured to measure, store, process and / or transmit one or more recorded parameters.

  For example, described herein is a garment adapted to continuously monitor a wearer's local breathing. A shirt for monitoring breathing: a shirt body made of fabric, wherein the body is configured as a compression garment that stretches and contracts to hold the shirt against the wearer's torso; A plurality of respiration sensors disposed in different regions of the body, each respiration sensor comprising a conductive ink trace or a conductive elastic strip printed on the outer portion of the body, and one or A plurality of respiration sensors connected to local conductive connectors; a respiration sensor; and an interface (eg, a module interface) disposed on the body, wherein the local conductive connectors for each respiration sensor are In addition to connecting to an interface, the interface further detects a resistance from each of the conductive connectors by a processor (eg, a Configured to connect to the service manager unit) may include an interface.

  In general, the respiration sensor may be local. Different sensors (eg quadrants) of the shirt body can be covered by different sensors, thereby detecting and monitoring “local” breathing. As the wearer tries to breathe and the garment (which fits the body) stretches and contracts, local breathing (motion) is detected by variations in the resistance of the conductive ink traces in each of the different regions. .

  Any of the garments described herein can also be referred to as wearable electronics devices. As described above, these devices (garments) typically may include: a compressed fabric, and at least one stretchable and conductive ink pattern on the garment. The conductive ink pattern typically includes a layer of conductive ink (which can itself be formed by laminating multiple layers of conductive ink to form a final thickness), and (insulating) It includes a layer of adhesive and an intermediate region between the two, where the conductive ink and the elastic adhesive are partially combined, for example in a gradient region. The intermediate region may be thinner than the conductive ink layer, approximately the same thickness, or thicker than the conductive ink layer, while the adhesive layer may be thicker.

  The conductive ink pattern may include multiple layers of conductive ink.

  The thickness of the elastic adhesive layer may be greater than the thickness of the gradient area, and the thickness of the gradient area may be approximately the same as or greater than the thickness of the conductive ink. For example, the ratio of the elastic adhesive, the intermediate (gradient) region, and the conductive ink is approximately 1.1-5 (adhesive): 0.8-1.2 (intermediate region): 0.5-1. 2 (conductive ink). In one example, the thickness of the ink portion of the conductive ink pattern is about 30 to 70 μm, the thickness of the transition region (gradient / intermediate region) is about 30 to 90 μm, and the thickness of the adhesive (bonding) region. Is about 100-200 μm.

For example, the bulk resistance may be about 0.2 to about 20 Ω * cm, and the sheet resistance may be about 100 to 10000 Ω / □. In one example, the bulk resistance was measured as 11.5 Ω * cm and the sheet resistance was measured as 1913 Ω / □. The resistance of the conductive pattern can vary with the applied stretch.

  In general, the resulting conductive ink pattern is extremely stretchable, while maintaining its electrical properties and not breaking. For example, the conductive ink pattern may be configured to be stretched without breaking up to 500% of the length of the stationary state.

  Any of the conductive ink patterns described herein may be formed as a sensor, all or part of a trace, and / or as an electrode. The conductive ink pattern may be connected to another (eg, more rigid) conductive material. For example, a conductive ink pattern can be connected to a sensor module or an interface for a sensor module by using a conductive ink pattern formed as a trace, or by connecting to a conductive thread or wire that is also attached to clothing. Can connect. For example, the device (garment) described herein may include a conductive thread coupled to the garment and connected at one end to a conductive ink pattern.

  Generally described herein are devices for detecting and monitoring physiological parameters such as breathing, cardiac parameters, sleep, emotional state, etc. (including but not limited to clothes such as shirts, pants, etc.) ). In particular, described herein are stretch conductive sensors and connectors that attach (eg, sew, bond, etc.) to garments, particularly including compression garments, or in some variations garments. It may include stretch conductive inks, elastics and traces that can form sensors, conductive traces, and / or contacts by printing on.

  US patent application Ser. No. 14 / 023,830, filed Sep. 11, 2013, entitled “PHYSIOLOGICAL MONITORING GARMENSS” (incorporated by reference into this application), describes exemplary garments. Any of these can be modified as described herein.

  Any of the garments described herein were placed directly on the garment (eg, shirts, shorts, or any other component of the wearable device, ie, balaclava, socks, gloves, etc.) or are described in more detail below. One or more sensor manager systems (SMS) integrated into the garment as described in. The SMS may include an electronic board. The connection to the SMS can be made by a connector (eg, a sewn zigzag connector) that includes a wire ribbon material that can be included as part of the garment. In some variations, a length of rigid material (eg, Kapton) to which conductive traces are attached may be used.

  SMS integrated into clothing (as opposed to being provided by a separate device such as a smartphone) can provide a number of advantages. For example, an integrated SMS can manage a relatively large number of connections with different sensors, process signals (e.g., regardless of the number of signals being processed), and communicate with the phone via a single mini USB cable. Can communicate. Regardless of the number of sensors that will be included in future devices (eg shirts, tights, gloves, socks, balaclava, etc.), the connection between the SMS and the sensor module (eg phone) is always a single 5-pin It may be based on a USB connection, thus substantially reducing the size of the female and male connectors from the device to the phone module. In a typical configuration, the SMS connects to a male connector through a UART (Universal Asynchronous Transmitter / Receiver) module, which communicates with the mobile through another UART and UART-USB module (attached schematic and drawings). checking).

  The integrated SMS can be placed at different locations on the garment. For example, it can be placed at the base of the neck between the scapula, the waist of the tights, the arms, the chest, or even socks, gloves, balaclavas, and the like.

  The SMS can also be configured to communicate with different phones for the device. As described above, integrated SMS allows multiple connections (pins) to be connected to different multiple sensors / outputs. For example, an accelerometer may require five pins if the SMS is present in a sensor module (eg, a mobile phone). An SMS integrated into a shirt may require fewer connectors. For example, SMS may only require two pins. For more sensors, such a number of connectors may not be feasible without using integrated SMS.

  In general, the SMS may be a module (chip) that manages signals from and to the sensor, and can function as an interface between the communication system (a sensor module including a telephone or the like) and the sensor. The SMS can manage the connection and spare interface between them. For example, an integrated SMS may include a physical connection to the sensor and can manage the path that processes the signal and transmits between the sensor and the sensor module and / or other analysis or control components. The SMS may also include a multiplexer or may be connected to a multiplexer so that readings can be alternated between the various sensors to which the multiplexer is connected.

  In some variations, the SMS can provide adequate power supply to passive or active sensors. SMS can obtain power from the mobile system through a port, such as a USB port. The integrated SMS can communicate from one side to a sensor module (eg, a communication system / telephone configured as a sensor module) through a USB port. The SMS can function as an interface or bridge between the sensor and the sensor module.

  Further, any of the integrated SMS described herein includes on-board processing (eg, pre-processing), including but not limited to amplification, filtering, sampling (sampling rate control), etc. You may comprise so that a preliminary | backup process may be included. Integrated SMS may also encode signals from one or more sensors. In some variations, the SMS may include an on-board microcontroller. Furthermore, the integrated SMS may also manage the communication protocol to / from any or all of the sensors as a whole, and may perform analog-to-digital conversion (if the signal is analog), You may communicate with the USB shared port before going to USB. For example, the SMS may be configured to convert the signal to a UART-USB signal protocol.

  Additionally or alternatively, any of the integrated SMS may be configured as a signal transceiver. For example, an SMS integrated in a garment may be adapted to convert parallel signals into serial signals (in data order).

  As described above, the integrated SMS may be arranged at any position on the clothes, for example, at the neck region or in the vicinity thereof, or at the periphery. Although the SMS described herein are referred to as “integrated” SMS, these SMS may be included on the garment or in the garment (eg, in a pocket or enclosure). However, in some variations, they are not physically connected / coupled to the fabric, but instead are placed on the garment. Thus, any of these SMS may be referred to as dedicated or special purpose SMS rather than (or in addition to) integrated SMS. For example, the SMS may be placed under the female connector (stored in the female connector) as part of the garment. When washing clothes, the SMS may be washed with the connector and tip. The pins and SMS are waterproof.

  In some variations, SMS connectors (eg, pins / ports) are adapted to be water resistant / waterproof. For example, the pins used can only be opened when engaged with a male pin, for example, but otherwise a waterproof connection can be formed by a connection that is closed and waterproof.

  In any of these integrated SMSs, the SMS is part of the garment and is worn with the garment. The SMS module can prepare the signal for transmission by pre-processing one or more signals.

  Thus, in any of the garments described herein, each garment (onboard) is not separated from the garment as part of a separate sensor module, such as a general purpose smartphone that can be held in a garment pocket as described above. An SMS (Sensor Management System) positioned on / dedicated) may be included. Each garment may have an SMS (chip / microchip), and by means of the SMS, the garment can have connectors (female and male) with a large number of pins (input / output), thereby Data from all sensors in (shirts, tights, and accessories such as gloves, socks, balaclavas) are first processed by SMS and then phone / communication module through connection (eg only 1 or 2 pins or more) Can be sent to. In general, some of the garment sensors and components described herein may require multiple connections independently, and thus dedicated SMS can be extremely useful. For example, an IMU may require 5 pins, and as many as 20 (or more) IMUs may be included as part of the garment in addition to other sensors. Thus, the use of dedicated SMS can allow the garment to manage multiple data connections / contacts.

Sensors In addition to the sensors described in US patent application Ser. No. 14 / 023,830, which are incorporated herein by reference in their entirety, such as touch point sensors, respiration sensors, bioelectric sensors, and the like, In any case, additional sensors may be included. For example, the garment may include one or more skin conductance sensors. Sensors for measuring skin conductance are two conductive conductive inks (see below) placed at the location of the third phalange of any pair of fingers (thumb, forefinger, middle finger, ring finger and little finger). Can be made with an annular ring. In some variations, the shirt sleeve has an integrated extension for this purpose at the wrist location. Skin conductance as a function of sweat level is measured as the reciprocal of the electrical resistance between the two considered “electrodes” (annular rings).

  Another integrated extension of the device described herein includes a full glove that incorporates optical fiber based pulse oximetry in addition to or instead of the skin conductance sensor. The use of optical fibers may allow other types of sensors to be incorporated. Further, the full or partial globe may include additional sensors such as accelerometers, inertial measurement units (IMUs). Such glove-based sensors can enable applications in specific activities (eg playing musical instruments, typing, etc.). The glove or pair of gloves may be configured to connect to other garments (eg, shirts, etc.), or may be formed as a sub-region of another garment (eg, finger area / shirt with glove, etc.).

  Socks or balaclava extensions that incorporate other types of sensors such as accelerometers, inertial measurement units (IMU), EEG electrodes, etc. are similar to the above-mentioned gloves. This allows for use in specific sports (eg football) and activities (eg playing chess).

Manufacturing Process In general, the manufacture of any of the garments described herein may include configuring the garment so that the sensor is held in close proximity and in stable contact with the skin. Thus garment sizing can be very accurate, especially in the following areas: chest (because the pectoral muscles and breast sizes are different even with the same body size), abdomen (same reason), armpits, forearms, etc. Thus, the garment can not only be made from compressed material, but can also be fitted / manufactured accurately. The design process may also include garment cutting.

  Thereafter, any of the garments described herein may be printed, for example, by printing and transferring conductive ink traces and / or insulators. This printing may be performed by a cylinder type machine using thermal transfer technology (because printing is relatively accurate and fast). For example, the transfer on both sides of the fabric is carried out at 150 ° C. for 15 seconds. Alternatively, the garment may be printed by 3D printing, as briefly discussed below.

  Insulators may then be applied (eg, when using capacitive touch points, such points may be insulated). The area inside the electrode of the capacitive touch point (ie, in contact with the skin) may be insulated by thermally welding a layer of high quality polyurethane film that accurately reproduces the shape of the electrode. The size of the insulating layer may be slightly larger than the size of the electrode, thereby preventing “lateral” contamination of the biopotential with a complete cover.

  In a variation that uses a more conductive connection, the apparatus includes the addition of a more highly conductive substrate and materials such as the wire ribbon material described herein (eg, a sewn zigzag connector). It's okay. Thus, the forming process may include the application of these wire ribbon material connectors, which connect the end of the wire (forming the wire ribbon material) to one or more sensors and / or SMS components. May be included. The wire ribbon material may include a compressed woven substrate that may be fused, bonded, sewn or otherwise connected to the body of the garment. For example, wire ribbon material (eg, a sewn zigzag connector) can be secured to the fabric with high quality polyurethane tape for heat welding applications once positioned. In some variations, a more rigid or semi-rigid substrate such as Kapton may be used rather than (or in addition to) the wire ribbon material, on which electrical traces and / or circuits The configuration may be printed. In order to maximize exercise comfort, the electronics on the Kapton may be designed to have a single layer to minimize its thickness.

  Subsequently, the clothes may be sewn. Sewing may be performed by conventional processes, but in some variations, sewing over conductive ink, wire ribbon material, or Kapton trace may be avoided.

  Simultaneously or subsequently, by performing soldering, a region of printed wire ink material, and / or an area containing additional (eg Kapton) substrate for higher conductivity traces, printed conductive ink sensor, It may be connected to electrodes and / or traces. For example, soldering between ink traces and Kapton terminals may be performed using a conductive epoxy and subsequently covered with a high quality polyurethane film.

  Thereafter, in some variations, for example, integrated SMS modules and connectors may be secured and covered by attaching a semi-rigid collar region. The collar may be made of a polyurethane material that takes the shape of the user's shoulders and may be applied to a custom-made plate to fit the body surface in the neck region by heat welding with a transfer machine.

  In some variations, the method of forming a garment may also include the addition of a “stretch limiter” made of a strip of polyurethane material with limited stretch. They may be positioned by thermal welding near the long ink trace (eg breathing trace) on the inner part of the garment, so that the trace can be destroyed or must be avoided for functional and aesthetic reasons Overstretching (e.g., during wearing) that can determine permanent stretch can be prevented. In order to increase the strength of the stretch limiter, they may be positioned in a path extending between the two seams.

  In some variations, the garment may be manufactured by installing a silicone cord. To avoid stretching of the garment and its sensor when the user is wearing and wearing the garment, a silicone cord is applied to the lower edge of the garment (eg by thermal welding) You may extend all around. This allows the wearer to easily lower the shirt from the armpit to the waist after inserting the collar and sleeve without overstretching the garment.

  As mentioned above, the garments described herein can be made in whole or in part by 3D printing techniques. For example, sensors and / or conductive traces and / or connectors can be manufactured by 3D printing. In some variations, a fabric (eg, a compressed garment fabric) can function as a substrate for 3D printing. In some variations, the fabric itself may be generated or modified by 3D printing. Thus, the garment can be made by transfer and direct printing (3D printing). In one example, a 3D printer for manufacturing a garment that includes an integrated sensor such as those described herein may include at least three nozzles: one nozzle adapted to print a compressed garment fabric. One nozzle may be adapted to print / insert stretchable conductive ink; and one nozzle may be adapted to print / insert sensor and / or electronics. Currently practiced, including weaving a fabric (eg, from a thread), printing electronics and sensors on the fabric (or printing on a substrate and then transferring to the fabric), and then sewing the fabric. In contrast to the method, 3D production can go directly to printing threads, inks and electronics based on accurate personal measurements from one person, which can be more accurate and quick .

Materials In general, the garments described herein may include a compressed fabric to ensure that the sensor is in good and constant contact with the skin. For example, the front of the shirt may have a lower percentage of elastane (5-20%) than the rest of the body, which may contain a relatively high percentage of elastane (15-40%). The fabric may be stretchable in two directions (in one direction) so that at least the stretchable side is positioned horizontally with respect to a human body that dynamically stretches horizontally rather than vertically. May be positioned. In general, the compressed fabric can be any fabric having material properties associated with the compressed fabric described herein. Examples include materials such as woven fabrics made of elastic polyurethane fibers (eg, elastin fibers, lycra, etc.).

  As discussed in more detail below, any of these garments may include a stretchable conductive ink and / or a stretch insulator that covers / encloses the conductive ink. Both conductive ink and insulator can stretch up to a few percent, up to X% (eg stretchable up to 5%, stretchable up to 6%, stretchable up to 7%, stretchable up to 8%, max Stretchable up to 9%, stretchable up to 10%, stretchable up to 11%, stretchable up to 12%, stretchable up to 13%, stretchable up to 14%, stretchable up to 15%, stretchable up to 16% Stretchable up to 17%, stretchable up to 18%, stretchable up to 19%, stretchable up to 20%, stretchable up to 20%, stretchable up to 21%, stretchable up to 22%, up to 23% Stretchable, stretchable up to 24% Maximum possible stretch up to 25%, can stretch up to 30% can stretch up to 35%, it can stretch up to 40% can stretch up to 45% maximum, may be up to 50% stretchable, etc.). This is also “X% super stretchable” (eg 5% stretchable, 6% stretchable, 7% stretchable, 8% stretchable, 9% stretchable, 10% stretchable) 11% stretchable, 12% stretchable, 13% stretchable, 14% stretchable, 15% stretchable, 16% stretchable, 17% stretchable, 18% stretchable, 19% Super stretchable, 20% stretchable, 21% stretchable, 22% stretchable, 23% stretchable, 24% stretchable, 25% stretchable, 30% stretchable, 35% stretchable Possible, stretchable over 40%, stretchable over 45%, stretchable over 50%, etc.) It can be expressed. “Stretchable” is typically stretched from a starting length / shape (eg, by applying a force such as a tensile force), and approximately the starting length / It means that the shape can be restored. In some variations, in addition or alternatively, if it means to withstand breakage when a deformation force (elongation or strain from the original length / shape) is applied (and eventually released) There is also. Examples of stretchable conductive inks and characteristics of such inks are provided below.

  As mentioned above, any of the garments may also include a substrate that is attached or formed as part of the garment for a more conductive pathway, such as a Kapton film. Other flexible wearable substrates may also be included. Any of the garments may also include one or more polyurethane films and tapes (eg, high quality polyurethane films and tapes) for sewing and heat welding applications. Furthermore, any of the garments may also include an electrically insulating material (such as a polyimide material) for covering / insulating the conductive traces, forming part of the sensor, and the like.

  A substrate such as Kapton may be fixed on the garment. For example, the substrate may be sewn and / or adhered with an adhesive or the like. The substrate may be held in a garment pocket or other area. As described above, any of the garments may include a limiter (eg, a stretch limiter) of a second material (eg, a fabric material that is less stretchable than the compressed garment).

  Any of these garments may also or additionally include silicone for sewing and heat welding applications.

Stretchable conductive ink In general, the stretchable conductive ink products described herein may be formed of an adhesive (eg, a binder such as acrylic, polyamide and other adhesives) on which a conductive solution is formed. A printable mixture is applied. The wet applied conductive solution (which, for convenience, may be referred to as conductive ink, even if the final conductive ink product includes an adhesive material layer) is typically It is applied as a layer on top of the adhesive layer, thereby forming an intermediate region between the adhesive and the wet applied conductive solution. This intermediate region can be important with respect to the conductivity and stretch properties of the resulting conductive ink material. The intermediate region is a gradient region in order to define a concentration gradient between the adhesive layer and the conductive solution (conductive ink) to be wet applied. This is illustrated and described below.

  Stretchable conductive inks (wet-coated conductive inks laminated to an adhesive) typically have a percentage of conductive material (eg, about / approximately 20%, 25%, 30%, 35 %, 40%, 45%, 50%, 55%, 60%, 65%, 70%) and biocompatible binders (eg, acrylic binders that do not contain formaldehyde, such as aqueous acrylic binders and aqueous polyurethanes), concentrated Agents (eg, polyurethane thickeners), and optional water retention agents and / or solvents (eg, propylene glycol). The stretchable conductive inks described herein generally meet the lowest conductance and the lowest stretch properties. Stretchable conductive inks are also optionally defoamers (eg 1-butanol) to eliminate air / bubbles during processing, catalysts (eg to aid binder crosslinking) (eg amine compounds or metal complexes) As well as additional additives that may aid in the printability and stability of the product.

  In one example, the stretchable conductive ink (and particularly the wet applied conductive ink portion) is: 50% carbon black, 40% acrylic binder completely free of formaldehyde, 5% propylene glycol, and 5% Formed with polyurethane thickener. The conductive material (carbon black) may be particles. Carbon black may be preferred compared to other conductive materials, particularly silver or other metals. Examples of other conductive materials include graphene, graphite, and coated mica (for example, mica coated with an oxide such as tin dioxide doped with antimony).

  The conductive inks described herein are not only conductive but also stretchable, and thus can function properly on compressed clothing. Furthermore, the stretch conductive inks suitable for forming the garments described herein may also be suitable from an environmental point of view (eg, the formaldehyde concentration is less than 100 ppm) and can withstand washing. (Electrical and elastic properties are preserved after multiple washings).

  Experimental studies have shown that the stretchable conductive ink composition described herein (laminated structure comprising an intermediate gradient region between the adhesive and the wet-applied conductive ink) is stretchable. Has been confirmed. Figures 5 and 6 show preliminary results of tests performed on samples of conductive ink printed on a compression textile as described above. A video camera was used to demonstrate that no breakage occurred in the ink during stretching (eg, examined for length changes up to 13 mm). Conductance (eg, resistance) varies from approximately 1.6 kΩ to 2 kΩ, depending on the applied force, while linear stretch was observed up to 1.1 N (eg, at approximately 1.1 N without breakage, Stretched to approximately 13mm). In general, the stretchable conductive inks described herein are stretchable to a force of at least 1N (eg, up to at least 2N, up to at least 3N, up to at least 4N, up to at least 5N, up to at least 6N, etc.), and / or Or at least 5 mm (eg, up to at least 6 mm, up to at least 7 mm, up to at least 8 mm, up to at least 9 mm, up to at least 10 mm, up to at least 11 mm, etc.) (without breakage) and / or applied stretch force It may be within a performance range that can be stretched to a certain ratio between (N) and the length of extension (mm), for example to about 1 N / mm. Surprisingly, in the experiment shown in FIG. 5, the tested conductive traces did not show any damage up to approximately 2N. This is a reasonable approximate maximum force that can be applied when applying / wearing clothes. Neither macro (visible with the naked eye) or micro damage was seen.

  In general, the resistance of a stretchable conductive ink can depend on the size of the trace, including thickness, length (which can vary with stretch), and can be left stationary and a given stretch force (or force / stretch length). ) May be less than about 5 kΩ (eg, about 4 kΩ, about 3 kΩ, about 2 kΩ, etc.). In general, the resistance may be in the range of several hundred Ω to several hundred kΩ. In FIGS. 5 and 6, the stretchable conductive ink to be tested is printed onto a compressed garment fabric to a length of 60 mm and a width of about 10 mm, and 8 layers of ink are applied and less than about 2 mm (eg, approximately 1 mm or less). A final thickness of was formed.

The connection can be made through a support substrate (eg, Kapton) that includes a trace, and the trace can be connected through a connector positioned within the inner portion of the upper body garment (eg, the lower edge region of the upper body garment).

  In general, the garments described herein may include a body formed of fabric. Compressed woven materials are particularly useful. The body may include a plurality of sensors positioned at predetermined positions on the garment. The sensor may be on the inside of the garment (eg, facing the wearer) or on the outside of the garment. The connector may connect the sensor to one or more sensor manager / sensor modules (SMS) that may include a processor. The SMS may directly transmit or connect / couple to the sensor manager unit (SMU) to record / analyze / transmit the sensed data, or may perform some or all of these functions by itself. . In general, a sensor may be formed of at least a portion of the stretchable conductive ink structure described herein (eg, as used herein, a “stretchable conductive ink” structure is defined herein. May represent wet applied conductive inks, adhesives, and gradient / intermediate combinations between them). Sensors that include stretch conductive ink may include touch point (eg, capacitive) sensors, skin electrode sensors, and the like.

The conductive elastic ribbon may form a strain gauge or other sensor. The connector may be formed of a stretchable conductive ink and / or a conductive elastic ribbon. In some variations, the connector is formed of a wire ribbon material (eg, a sewn zigzag connector), in which the enameled wire is sewn in a sinusoidal / zigzag pattern on a strip of material (eg, a compressed fabric). A ribbon is applied to the body of the garment. In some variations, the connector may be a rigid or semi-rigid substrate (such as Kapton) to which electrical traces and / or circuitry is applied, and the substrate adheres within a fabric such as a compressed fabric. And / or coated and attached to the body of the garment or directly to the body of the garment.

The expandable support structure may be used with a harness. The harness may be separate or the harness may be integrated into the garment.

  For example, described herein is a garment configured to sense an electrocardiogram (ECG) signal for recording and / or analysis. Such clothing may be configured to connect to the upper body of the wearer (subject) and may be in the form of a shirt or may include a torso cover. These garments may include five or more electrodes, for example six chest electrodes, and three or more electrodes for each of the right arm, left arm and leg. Additional electrodes may be used. In some variations, the chest electrode is an electrode pair that may have redundancy.

  Any of these garments may also or alternatively include one or more respiration sensors. In general, these respiration sensors include textile and / or conductive ink based strain gauges. For example, the strain gauge can be formed of a stretchable conductive ink as described herein and / or a conductive elastic strip as described herein. In one variation, the garment includes 10 ECG sensing electrodes and 2 breath sensors (strain gauges). The ECG electrode may be placed on the chest of the garment so that the ECG electrode contacts the user's skin at the location where the standard 12 leads are placed. The respiration sensor may be positioned on the garment so that when the compression garment is worn, the respiration sensor is held relative to the body near the xiphoid process of the subject's torso and the umbilicus. The sensor may be connected to the SMS unit by a trace, such as an elastic strip with a copper wire ribbon and / or a sewn zigzag connector. Garments include shirts and, in some variations, tights.

  Also described herein is a garment configured to measure respiration (including local respiration). For example, the garment may be configured to include a shirt portion formed of a compressed fabric that detects respiration (eg, to allow plethysmography of the sensed signal). The device may also include electrodes as described above to detect simple ECG signals (eg, two electrodes, or a single lead or multiple leads, eg, three leads, five leads, With 12 leads). For example, twelve respiration sensors (eg, conductive elastic strip strain gauges described herein) may be included. A respiration sensor may be positioned for positioning on the wearer near the sternum angle, the third rib gap, the xiphoid process, the lower rib edge, above the navel, and below the navel. There may be a dual (eg left / right side of the wearer's torso) sensor. These sensors can be connected to one or more via connectors such as a zigzag connector that is sewn (eg, a strip or tube or a compressed garment is sewn sinusoidally with insulated / enamelled copper wire). Can be connected to an SMS unit. See, for example, FIGS. 44A-44B showing 12 respiration sensors.

  The garments described herein may also be configured to sense sleep disorders and may include a head cover portion and a torso and / or pant portion. Such garments may include, for example, EEG electrodes (eg, one or more), and associated ECG electrodes, respiratory sensors, and one or more inertial measurement units (IMUs), thereby providing activity levels and basics. Detect motion. For example, a garment may have 21 EEG electrodes (made of stretchable conductive ink) (or standard medical electrodes may be used), 2 ECG (formed of stretchable conductive ink) It may include an electrode and two respiration sensors (formed of conductive elastic strips) and five IMUs. The EEG electrodes can be positioned as a simplified 10-20 system on the head cover, while the ECG electrodes can be positioned on the right and left torso portions of the garment. The respiration sensors can be positioned so that they are worn near the xiphoid process and the navel. The IMU can be positioned on the lower back and limbs (eg, arms on shirts, legs on tights).

  Also described herein is a garment for use as a fitness article or assistive device. For example, described herein is a garment configured as a fitness device, which may include sensors for detecting body status and athletic performance. These garments can monitor body status (eg, being in a healthy state) by sensing and / or measuring indicators of heart rate, breathing, body fat, exercise, posture and stress level. For example, one variation of a fitness garment includes two ECG sensors (eg, electrodes formed from stretch conductive ink), one respiration sensor (eg, formed from a conductive elastic strip), and four It has a body made of compressed fabric with an IMU. The ECG electrode can be positioned on the garment to be held against the right and left torso parts, and the respiration sensor can be placed on the garment to be held against the xiphoid area, and the IMU , Lower back, one for each forearm, and one in the SMS unit (eg, near the neck area). In some variations, the device may also include body fat sensors in the wrist, neck and umbilical areas. The body fat sensor may be an electrode (eg, formed of a stretchable conductive ink).

  Another variation of fitness clothing (eg, general fitness clothing) may be configured as a shirt worn on the upper body. As mentioned above, these garments can be used to monitor overall health, and these garments compare the data to the baseline and can be used for coordination, balance, stamina, “breath”, Can be operated by a controller that evaluates basic fitness skills such as strength, flexibility and reflexes. In some variations, the garment has at least three (eg, four) IMUs on the upper portion (shirts, eg, upper and lower arms, left / right), lower portion (eg, pants / tights, upper and lower limbs, Include at least 3 (eg, 4) IMUs (on the left / right side) and respiratory sensors (in the area worn against the umbilical area). See, for example, FIGS. 22A-22D. In the example shown in FIG. 22B, the system has two parts: a shirt for detecting posture and monitoring fitness; and a pant that can be connected to the shirt or separately connected to the processor. In FIG. 22B, shirt 2204 and pants 2205 include EMG sensor 2221 shown as parallel lines of sensors. The IMU 2225 is also positioned along the upper and lower limbs, the upper and lower arms, and the back so that changes in posture can be detected. Integrating the elastic material band 2231 into the compression garment helps to hold the electrode (eg, EMG 2221) against the skin, as shown by the shaded area.

  In general, any of the garments can be operated / connected to a processor capable of storing, transmitting, compressing and / or analyzing recorded data.

  Examples of these various types of clothing are described below.

Clothing for detecting respiration Clothing may be adapted to detect respiration, particularly local respiration. Such a device can be used in the request of any medical professional or anyone wishing to monitor respiration. The respiratory monitoring device may be adapted for continuous and accurate monitoring of respiration, including monitoring of respiration in one or more areas. Complete and accurate measurements of multiple breathing parameters (described below) are arranged in patterns (eg “zigzag” patterns) arranged in different areas of the garment to be positioned around the wearer's torso Alternatively, a plurality of stretchable conductive ink traces can be used, or in some variations, a conductive elastic strip (eg, an elastic strip impregnated with a conductive material) can be applied to the stretchable conductive ink trace. In addition to or instead of the stretchable conductive ink traces described above. Regions that include the length of the stretch conductive breath sensor include: the front of the shirt, the back (back) of the shirt, each or one of the two sides of the shirt, and the like. Subregions of these regions can also be used. Stretch conductive respiration sensors as described above may have a resistance that varies slightly with stretch, and this property is used to exercise the body as the sensor is stretched while worn on the body. Can be detected and / or measured.

  As described below, in some variations, four or more respiratory signals may be measured to determine local breathing. For example, twelve signals may be measured by grouping the variable resistance of the traces (or the average of multiple traces) placed in the following areas: (1) Front right top (eg six traces) (2) front upper left (eg 6 traces); (3) front lower right (eg 5 traces); (4) front lower left (eg 5 traces); (5) rear upper right ( (6) rear upper left (eg 6 traces); (7) rear lower right (eg 5 traces); (8) rear lower left (eg 5 traces); (9) Side top right (eg 3 traces); (10) Side right bottom (eg 5 traces); (11) Side top left (eg 3 traces); (12) Side left bottom (eg 5 traces) Trace). Based on the placement of stretch sensitive conductive traces and / or elastic strips, parameters can be extracted by analyzing different signals. For example, the measurement of total respiration can be determined by summing the signals from all the stretch sensors in each region (eg 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12). Thoracic volume measurements can be determined by summing the signals from the upper region (eg, 1 + 2 + 5 + 6 + 9 + 11). The measurement of abdominal respiratory volume can be determined by summing the signals from the lower (abdominal) region (eg 3 + 4 + 7 + 8 + 10 + 12). Thoracic breathing area measurements can be determined by summing only the areas associated with the right rib cage (eg, 1 + 5 + 9), and left ribcage measurements can be determined by summing only the areas associated with the left rib cage (eg, 2 + 6 + 11). . The measurement of respiration at / in the right abdominal region can be determined by summing the signals from the right abdominal region (eg 3 + 7 + 10), and similarly, the respiration measurement at / in the left abdominal region can be determined by the signal from the left abdominal region. It can be determined by summing (eg 4 + 8 + 12).

  From the time course of a signal (for example, a signal of total respiratory volume), breathing such as breathing frequency (f), inspiratory time (Ti), expiratory time (Te) and / or duty cycle [Ti / (Ti / Te)] Can be determined, recorded, measured and / or displayed (so that any of the signals can be detected in the garment).

  For example, FIGS. 1A-1C illustrate one variation of a shirt for detecting and / or monitoring (including continuously monitoring) respiration. In any of these examples, an apparatus that may be interchangeably referred to as a device or system may be configured to continuously and accurately monitor respiration. The shirt shown in FIGS. 1A-3A is a compression garment (shirt) typically composed of the following four parts: (a1) 1903 front and sides; (a2) 1905 back (back); (a3 1907 right arm; (a4) 1909 left arm. These portions include conductive ink, conductive connectors (e.g., conductive materials and / or kapton in which wires are sewn in a zigzag pattern), and layers of insulating material, for example, deposited by a transfer process, It is sewn together.

  In general, conductive ink traces can be used as sensors. In FIGS. 1A and 1B, the sensor is a plurality of conductive ink traces that are stretchable traces. Conductive inks (including conductive ink, adhesive, and gradient areas) can be used to form conductive traces 1919 as described herein. Any of these devices may also include a sensor manager unit. The sensor management unit 1921 may be a processor located on the garment (eg on the back), which connects to an interface for connecting the sensor to the processor. The processor may be a smartphone or other handheld device, for example. The apparatus may have a communication unit, which may be separate from the processor or integral with the processor (and / or may include its own dedicated processor). For example, the communication unit may be placed on the back or connected to the interface.

  Additional sensors including motion sensors may be used. For example, a 3-axis accelerometer (single or embedded in a communication system, for example) may be included.

  In general, any of these devices may include one or more wearer inputs, such as a “touch point sensor”. For example, two capacitive touch points 1933, 1935 placed on the arm may be used. The touch point sensor may include two electrodes (eg, one at a corresponding location on the inner surface of the garment and the other on the outer surface of the garment), which are: a conductive ink pattern; two conductive ink patterns A textile separating layer; and an insulating layer deposited on the inner conductive ink pattern layer. A connecting trace may be included between the outer electrode and a termination point located near the neck.

  The additional sensor may include one or more electrodes, such as an electrode that detects a heartbeat. For example, two electrodes 1941, 1943 for measuring heart rate (HR) made of conductive ink may be disposed on the inner surface of the right and left arms of the shirt. These electrodes may be connected by a conductive connector such as a conductive (kapton) trace that connects the HR electrode to a termination point near the neck, as shown in FIGS. 1A and 1C.

  In general, the breath trace may be positioned in any region of the body of the shirt and detects movement (expansion / contraction) due to breathing in that part of the body. A complete and accurate measurement of multiple breathing parameters (see below) can be obtained by applying conductive ink stretch traces to different areas of the body of the shirt (eg transfer process) for individual areas of the wearer's body. Can be provided by positioning in a “zigzag” shape. For example, conductive traces and / or conductive elastic strips may be positioned on the front and two sides of the shirt, the back (back) of the shirt, and various subregions of these parts.

  1A-1C, eight signals are measured by a sensor manager unit (processor) as voltage variations determined by the variable electrical resistance of a trace placed in parallel in the following areas:

  1. Front + side, top right (5 parallel traces);

  2. Front + side, upper left (5 parallel traces);

  3. Front + side, bottom right (5 parallel traces);

  4). Front + side, bottom left (5 parallel traces);

  5. Rear, top right (6 parallel traces);

  6). Rear, upper left (6 parallel traces);

  7). Rear, lower right (5 parallel traces);

  8). Rear, lower left (5 parallel traces).

  The vertical traces shown are made of conductive ink and / or conductive elastic strip and constitute the terminals of the total electrical resistance of these eight regions. These respiration sensors are connected to a termination point located near the neck (in the interface area). A processor or other circuitry may be used to detect / monitor the resistance. For example, in some variations, a sensor manager (processor) may be used to acquire and / or store, transmit, analyze, process, etc. the eight signals listed above. The processor may also incorporate and analyze, transmit, process, and / or store additional signals, including signals obtained by summing one or more combinations of multiple single signals. For example, as mentioned above:

  Total = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8

  Thorax signal = 1 + 2 + 5 + 6

  Abdominal signal = 3 + 4 + 7 + 8

  Right thorax signal = 1 + 5

  Left thorax signal = 2 + 6

  Right abdominal signal = 3 + 7

Left abdominal signal = 4 + 8
It is.

  From the time course of the overall signal, the following breathing temporal parameters can be obtained: breathing frequency (f), inspiratory time (Ti), expiratory time (Te), duty cycle [Ti / (Ti / Te )]etc.

  As described above, these signals can be stored, transmitted, analyzed, etc. by the processor and / or communication unit.

  1D, 1E, and 1F show another compression garment that includes a local respiratory sensor, similar to the garment shown in FIGS.

  As mentioned above, in some variations, the respiration sensor is a conductive sensor that has been treated to have a resistance that varies with stretch with relatively small (or negligible) mechanical hysteresis and very little electrical hysteresis at repeated loads. A breathing sensor, which is an elastic elastic strip. Such a sensor may be referred to herein as a conductive elastic strip sensor or a conductive elastic strain gauge. Figures 23-38 illustrate a method of making and using a variation of a respiration sensor configured as a conductive elastic strip. Described herein are conductive elastic materials and methods of making and using them. In particular, described herein is a method of forming a conductive elastic material that can be used as part of a sensor (eg, a stretch or breath sensor) on a wearable garment, particularly including a wearable stretch (eg, compressed fabric) garment. is there. The conductive elastic materials described herein can be used, for example, in any garment that includes breathing or other contact and / or stretch sensors.

  The conductive elastic material described herein can change resistance as it stretches, and thus can function as a stretch sensor. In addition, these materials have very high mechanical and electrical memory capabilities and can therefore have excellent mechanical and electrical properties when compared to other stretch conductive materials. This is because the material is, for example, 1.2 times its original standing length (or 1.3, 1.4, 1.5, 1.6, 1.7 times, 1.8 times, 1.9 times, 2 times, 2.1 times, 2.2 times, 2.3 times, 2.4 times, 2.5 times, 2.6 times, 2.times. 7 times, 2.8 times, 3 times, 3.1 times, etc.) means that the length can be restored to the same stationary state. The stretch dimensions (length, width, etc.) may be the same. In some variations, the material may be stretchable more in one dimension (eg, width) than in another dimension (eg, length). The upper limit of the stretch described above (eg 1.3 times the original length, or in some variations 1.5 times, 1.6 times, 1.7 times, 1.8 times, 1.9 times, 2 times Times, 2.1 times, 2.2 times, 2.3 times, 2.4 times, 2.5 times, 2.6 times, 2.7 times, 2.8 times, 3 times, 3.1 times, etc. ), The material does not exhibit significant hysteresis and is restored to its original standing length.

  Similarly, the material can experience little, if any, electrical hysteresis due to stretching below the relatively high stretch limit. For example, the material is 1.2 times its original standing length (or 1.3, 1.4, 1.5, 1.6, 1. 7 times, 1.8 times, 1.9 times, 2 times, 2.1 times, 2.2 times, 2.3 times, 2.4 times, 2.5 times, 2.6 times, 2.7 times After stretching to 2.8 times, 3 times, 3.1 times, etc., they can have approximately the same conductance / resistance. Further, the change in resistance due to stretching can be linear over at least a portion of the range. Thus, the materials described herein exhibit very little electrical hysteresis with use. Furthermore, these characteristics can be repeatable over a long period of time (eg, over hundreds, thousands or hundreds of thousands of stretch cycles).

  Finally, the recovery response time from stretching can be very rapid. For example, the material can be restored to initial performance measurements (in terms of length and resistance) within less than 5 seconds (eg, less than 4 seconds, less than 3 seconds, less than 2 seconds, less than 1 second, etc.). Therefore, the electrical restoration time is (less than the maximum stretch length, eg 1.3 times, 1.4 times, 1.5 times, 1.6 times, 1.7 times, 1.8 times the original length. Times, 1.9 times, 2 times, 2.1 times, 2.2 times, 2.3 times, 2.4 times, 2.5 times, 2.6 times, 2.7 times, 2.8 times, Less than 5 seconds over the entire stretch range (3x, 3.1x, etc.).

  It is believed that these properties, particularly electrical properties, of the material are due to the reduced molecular damage of the conductive material even during repeated stretch cycles. This can lead to an increase in the lifetime of the material. Furthermore, it is believed that the elastic properties (recovery from stretch) are obtained by a core elastic material coated with a conductive material (eg, a conductive coating). The core material is believed to maintain its elastic properties even when coated with a relatively thick coating of (dry) conductor.

  Figures 23-38 illustrate one method of making a conductive elastic material. Briefly, as shown with reference to the drawings, elastic materials, and particularly elastic wristband type materials, can be coated as described herein. FIG. 23 shows an example of an elastic material. Generally, the elastic material can be formed from a flat elastic material knitted or woven (like an elastic wristband). The knitted elastic body may be covered with a woven fabric. The material forming the elastic body and / or the cover may be natural (eg cotton, wool etc.) or rigid (eg polyester) or any combination thereof. For example, an elastic material, such as the material shown in FIG. 23, can be formed of a porous / absorbent material such as cotton and may include additional (eg, polymer) material woven or sewn into the cover material.

  The elastic material may initially be a relatively narrow and thin strip or band. For example, the width of the band may be about 0.1-3 cm (preferred thickness is about 1.5 cm). The material may include multiple sets of warp yarns (eg, elastic weave yarns) woven on or within the fabric.

  In general, conductive elastic materials are first coated with an elastic material, and in particular an absorbent or partially absorbent elastic material, with a suspension of conductive particles in a solution (eg immersed in the above suspension). Spraying the suspension, submerging in the suspension, etc.). Any suitable conductive material may be used, such as carbon black, metal conductive material (eg gold, silver, silver / silver chloride, graphene, oxide coated mica (as shown in FIGS. 24-26)) Etc.), but is not limited thereto. The conductive material may be a mixture of conductive particles suspended in a solution (such as water or an alcohol solution). The solution may include a substrate or binder and a solution of conductive particles. For example, the solution may be a solution of 0.1 to 25% binder (for example, acrylic, water-based polyurethane, etc.) and 99.9 to 75% conductive particles.

  For example, in FIG. 24, a solution of carbon black suspended in water is poured into a plastic container. As shown in FIG. 25, the uncoated elastic material in the initial state is immersed in the solution on both sides of the elastic ribbon and moved in the solution from end to end (from left to right), Coating. In FIG. 26, a uniform coating of the entire ribbon surface is obtained as shown. The coated ribbon may then be dried as shown in FIG. For example, the ribbon may be dried by applying heat and / or air (or vacuum). In FIG. 27, the coated ribbon is dried in a convection oven for 30 minutes.

  After drying, the core elastic material may be connected to the conductive end for attachment to a garment and / or an outer material (which typically will be applied with the outer material). May be formed of the same material as the material). For example, in FIG. 28, a pair of terminals (shown as copper terminals, but any conductive terminal may be used) are attached as shown in FIGS. For example, in FIG. 29, the copper terminal cuts the copper material (eg, into a rectangle about 20 mm long) and wraps the conductive elastic body at the edge of the ribbon with this terminal material (typically not elastic). Formed by. The conductive terminal material (eg, copper) may be elastic or have an elastic body (conductive elastic material) applied to secure the conductive terminal material to the conductive elastic ribbon as shown. You can do it. In FIG. 30, using a tool 3001 (for example, a plier), the conductive terminal is securely attached to the adhesive and accordingly to the conductive elastic body.

  With the terminals attached, the elastic material can be coupled to a wire connector such as the pre-prepared wire ribbon material shown in FIG. In FIG. 31, the wire ribbon material is sewn to the fabric strip by a pair of twisted wires 1010, shown as twisted enameled (insulated) wires (but using more than two wires). May be). These wires are sewn in a zigzag pattern to a strip of fabric (eg, compressed fabric), which may include a fabric adhesive or configured to be applied to another fabric (eg, garment) by heat. This allows the conductive connector to be applied directly to the fabric without the need to sew directly to the fabric and without providing a cover on the wire. The fabric to which the wire is sewn is typically the same material as the fabric to which it is applied (eg, a compressed garment fabric). In some variations, the side of the fabric (sometimes referred to as the applicator fabric) to which the zigzag pattern of the insulated wire is sewn contains fabric adhesive (including heat activated adhesive) or fabric adhesive It has been processed for use with the agent. In practice, long wires may be prepared in advance and cut as needed for application to the garment. Note that generally the wire ribbon material can be used as an electrical connector to connect one or more sensors to other parts of the garment described herein, including data modules and / or SMS components. This wire ribbon material may also be referred to herein as a wire ribbon material, or a sewn zigzag connector. This material is advantageously prepared in a long length and can be cut to a desired length for securing (eg, gluing) the garment and / or sensor.

  For example, in FIG. 32, the conductive elastic ribbon is placed in a wire-free region on the surface of the wire ribbon joined by thermal adhesive and connected to the end of the conductive wire. For example, as shown in FIG. 33, the conductor (wire) is soldered to the copper terminal.

  When attached to the conductive wire, the elastic ribbon can be encased within a fabric (eg, an insulating fabric, which may be the same as the fabric to which it is attached). In some variations, the elastic ribbon may be encapsulated within an insulator material and / or coated with an insulator. 34 and 35, the outside of the conductive elastic ribbon (including the contacts) is sealed to a width of approximately 33 mm using an adhesive tissue ribbon. The tissue (cover) ribbon can be secured over the elastic ribbon, for example, by thermocompression (when using a heat activated adhesive), as shown in FIG.

  The resulting ribbon comprising the conductive elastic material and the zigzag wire can then be attached to a garment such as a compression garment. For example, FIG. 36 shows a variation in which a breathing sensor is provided by securing the resulting assembly of conductive elastic bodies to clothing. The assembly can be attached by thermocompression bonding (eg, again using a heat activated fabric adhesive) as shown in FIG. The final results of this example are shown in FIGS. FIG. 37 shows a view of the inside of the garment (the assembly can be attached to the inside or outside of the compression garment as shown). FIG. 38 shows an outside view of the same garment. In FIGS. 37 and 38, the garment is configured as a breath sensing shirt (eg, a T-shirt).

  Thus, the conductive elastic strip described above can be used as part of a compression garment. What has been described above is a method of making and using a conductive elastic material that has very low mechanical and electrical hysteresis and can therefore be used as a respiration sensor for wearable compression garments. This conductive elastic material can be used as a respiration sensor or as part of a connector. A respiration sensor using a conductive elastic material can be formed of a strip of elastic material impregnated with a solution of conductive particles (e.g., carbon black) and dried (or at least partially dried). It can adhere to the end of the strip of elastic material impregnated. In some variations, the connector can be electrically connected to a wire ribbon material formed of enameled (eg, insulating) metal conductive wire sewn in a zigzag pattern on a strip of fabric, such as a compressed fabric. . The conductive particle impregnated elastic material and / or the wire ribbon connector material may be encapsulated in a woven material (such as a compressed woven material). The encapsulated sensor and one or more connected lengths of wire ribbon can then be attached to the garment as described above (see, eg, FIGS. 1A-1F).

  For example, FIGS. 44A-44B show one variation of a garment configured to measure respiration using a plurality of conductive particle impregnated elastic strips configured as strain gauges. In FIG. 44A, the garment is shown without sleeves, but sleeves may be included. The garment body may be made of compressed garment material and has a strain gauge sensor attached as shown. The respiration sensor is configured as a strain gauge having an elongated length of elastic material impregnated with a conductive material (eg, a carbon black solution containing a substrate / binding material as described above). The impregnated and / or coated elastic material strip may have a conductive metal end that is attached to the end region and is the same or similar compressed garment fabric material from which the body of the garment was made, for example It can be contained within. In FIG. 44A, six pairs of horizontally arranged respiration sensors 4403 formed of conductive elastic members are arranged at different heights along the torso region (eg, near the sternum angle, the third rib gap). , Xiphoid process, lower rib edge, upper navel, and lower navel). Using a sewn zigzag connector 4407 (formed from a separate strip of compressed fabric applied to the body of the garment after stitching a wire such as enamel-coated copper wire in a sinusoidal pattern) in FIG. Twelve sensors are connected to the SMS unit as shown in FIG. 44B showing the back of the garment. Each sensor can be connected at both ends to a different wire of the sewn zigzag connector so that changes in the electrical properties of the conductive elastic strip can be detected by SMS. The garment may also include additional sensors. In FIG. 44A, a pair of ECG electrodes 4409, 4409 'are shown, each connected to the SMS by one or more stitched zigzag connectors 4407.

  These garments can be manufactured as shown in FIG. 45, which shows three pieces of fabric (eg, back center 4419, right front body 4221 and left front body 4423) that form the body of the garment. Because the respiration sensor is continuous on the right and left sides, the right and left front bodies can first be sewn to the back before applying the sensor (arrow 4431). As already discussed, these different respiration sensors may correspond to different areas that can be examined separately.

Electrocardiogram (ECG) measurement garments Also described herein are garments that can be used to effectively and continuously monitor electrocardiogram (ECG) signals. For example, the garment may be adapted to measure signals by including multiple pairs of redundant traces between which devices (eg, garment control / sensing module, etc.) can be switched. In some variations, the SMS and / or sensor module can determine which set of electrodes between multiple redundant electrodes to use when detecting a particular lead for the ECG. 2A-2B, 3A-3B, and 4A-4B show a garment configured to measure ECG. Each of these garments includes redundant leads (two or more), where each redundant lead can detect a signal from an electrode that can be used to determine an ECG signal for that lead.

  The electrode used to detect the ECG signal can be formed of the stretch conductive ink described herein. In some variations, the electrodes are printed, applied or formed on one side of the garment (eg, the inner surface) and are adapted to be in continuous contact with the subject's skin to measure the ECG signal. The electrode is formed via conductive traces (eg formed by a combination of stretchable conductive ink and / or a stretchable conductive ink and a substrate such as Kapton having traces with higher conductance) via SMS. And / or can be connected to a sensor module. The SMS and / or sensor module can determine which redundant trace to use / present for the ECG signal, eg, based on signal quality.

表１：胸部電極の位置 For example, in FIGS. 3A-4B, electrode 2103 is formed as a series of electrodes composed of a circle of ink positioned at the standard point of a 12-lead EKG. In the garment (to be worn on the torso), the electrodes may be arranged so that the redundant chest electrode (a pair) is positioned corresponding to the V1-V6 positions when the garment is worn.

Table 1: Location of chest electrode

Similarly, leads can be placed at other locations on the shirt to measure RL, RA, LL and LA leads (limb leads) corresponding to:

  3A-3B show limb leads for the legs positioned at the lower edge of the torso garment, which can be used without wearing separate pants. The garment limb leads shown in FIGS. 3A-3B and 4A-4B do not include redundant electrodes, but may include them.

  In any ECG sensing garment, the garment structure including the additional harness area 2144 (eg, the yoke area) as shown by the shaded areas in FIGS. 3A and 4A allows consistent / constant measurements (even during exercise). Can be held against the body. This harness can be formed as a region that supports the ECG chest electrode, which is relatively high to hold the chest electrode on / to the body, even during breathing and other body movements Has supporting force (eg, applying pressure / force). For example, the harness region can be formed as an elastic corset (eg, width: 2 cm on the sternum and 4 cm on the xiphoid line), which extends along the sternum line, followed by the right and left sides of the xiphoid line. In the back, it converges on the spinal cord and extends to the neck, then separates again around the neck to the right and left, and finally converges on the sternum line. The corset material must have very high extensibility.

  The electrode and / or the peripheral region of the (eg, chest) electrode may include a silicone surface that assists in holding one or more electrodes against the chest and may prevent the electrode from sliding. For example, silicone can be placed on the inner surface of the shirt 5 cm beyond the mid-axillary line along the horizontal line, corresponding to the harness / corset position. This silicone can help to ensure that the ink electrode is fixed in a selected position and does not move with the patient's movement.

  As mentioned above, it is particularly useful when the electrodes include adjacent redundant electrodes. All electrodes (including redundant electrodes) can be connected to an SMS and / or control module to detect ECG signals, which SMS and / or control module uses (or some variations) Then, it is possible to determine which redundant signal is used in order to improve the overall signal quality, for example by selective filtering, averaging and the like. In some variations, unselected redundant signals can be ignored, and in other variations, the device can be configured to store the unselected redundant signals for later analysis. Both pairs (or more than two pairs) of electrodes may have signals that can be stored, transmitted and / or processed, and a decision regarding which redundant electrode to use to generate the ECG is made later. it can.

Also described herein is a garment that is configured to be worn to monitor a subject's sleep. Sleep monitoring can generally be used to measure sleep movement, breathing during sleep, body temperature (both deep and local body temperature), eye movements, and the like. Using such an indicator, the stage of sleep, sleep quality, sleep duration, etc. can be determined. Any of the garments described herein may be adapted to determine a sleep indicator and thus may be worn during sleep. These clothes are therefore comfortable and can be adapted for use by a sleeping person.

  For example, in FIG. 7A, the front of the garment is illustrated, which includes EEG (scalp electrode on the inner surface of the hood), face / eye EMG (to detect eye movement), and respiration detection. A head cap / hood 2205 having a nasal thermistor and a sensor 2209 arranged to detect jaw EMG (detecting jaw movement and the like). The hood may be integral with the shirt 2207 or attached to the shirt 2207 separately. In any garment, the various components (eg, shirts, hoods, gloves, pants, etc.) may be optional, and individual garments or groups of garments may be used. The shirt may be similar or identical to the breathing and / or ECG sensing garment described above. In FIGS. 7A and 7B, the torso region includes local respiration sensors 2225 (stretch conductive traces) for the front and side regions of the body, as well as EGC electrodes 2227 (but all of the V1-V6 lead electrodes are included). Not included). The garment also includes pants, including limb leads 2229 (for ECG detection) and / or EMG sensors 2219 for detecting leg movement / convulsions. A full glove or partial glove 2231 may also be included, which can measure a blood oximeter 2217 (eg, a pulse oximeter) at the end (eg, a finger).

  7A-7C illustrate one variation of clothing that can be formed as described herein and can include multiple sensors for determining sleep parameters. For example, in FIG. 7A, the front of the garment is illustrated, which includes EEG (scalp electrode on the inner surface of the hood), face / eye EMG (to detect eye movement), and respiration detection. A head cap / hood 2205 having a nasal thermistor and a sensor 2209 arranged to detect jaw EMG (detecting jaw movement and the like). The hood may be integral with the shirt 2207 or attached to the shirt 2207 separately. In any garment, the various components (eg, shirts, hoods, gloves, pants, etc.) may be optional, and individual garments or groups of garments may be used. The shirt may be similar or identical to the breathing and / or ECG sensing garment described above. In FIGS. 7A and 7B, the torso region includes local respiration sensors 2225 (stretch conductive traces) for the front and side regions of the body, as well as EGC electrodes 2227 (but all of the V1-V6 lead electrodes are included). Not included). The garment also includes pants, including limb leads 2229 (for ECG detection) and / or EMG sensors 2219 for detecting leg movement / convulsions. A full glove or partial glove 2231 may also be included, which can measure a blood oximeter 2217 (eg, a pulse oximeter) at the end (eg, a finger). Additional embodiments of garments that can be used for sleep monitoring are shown in FIGS.

  The SMS and / or sensor module may be adapted to process and / or analyze sensor input and to provide reports regarding sleep status (or status over time) for individuals wearing clothes.

  In general, these devices may be useful for sleep laboratories or home sleep laboratories. These devices can record all signals normally included in polysomnographic analysis, including breathing, for example, in a simplified manner, to know when the wearer exhibits odd-sex movements and the front of the shirt and Devices may only be needed in the four quadrants of the side; rib cage and abdomen. While it is useful for the wearer to have both an upper and lower part, it is equally useful to have a right / left side. It is also useful to use an ECG with a simplified (eg, two electrodes and wrist and leg) configuration on top of the torso. The garment sensor may again have redundancy as described above to have the best and most reliable ECG. In particular, a heart rate is used, which may not require a complete ECG. ECG recording (electrocardiogram electrodes) can be formed of stretchable conductive ink and can be arranged at a plurality of different positions. For example, in the jaw, lower part (muscle), it may be useful for use in polysomnography MG. Furthermore, ocular EMG may be useful for detection of REM and other sleep stages. As mentioned above, a thermistor (nasal height temperature sensor) can be used to detect airflow through the nose, similar to what is done in a sleep lab. An IMU (Inertial Measurement Unit) can be used on the arms and legs to detect limb movements. The IMU 2235 may also be placed on the back of the garment, which is useful for detecting the patient's position (turning over, lying on his back, lying down, sideways, etc.) and can detect a state of not being able to rest.

Garment Support Structure and Accessories Any of the garments described herein may include additional support structures to assist in securing one or more sensors to the body. Such a support structure may be expandable and may improve contact between the physiological monitoring garment disclosed herein and the wearer's skin. For example, the anatomy of the chest may prevent a sensor on the physiological monitoring garment from making good electrical contact with the patient's chest, as described herein. The support garment is sometimes referred to as a harness, which is a pressure to improve electrical contact between the electrode on the garment and the wearer's chest by wearing it on a physiological monitoring garment. Can provide. These harnesses (supporting garments) can be particularly useful for male wearers with large pectoral muscles and female wearers with large breasts. The support garment can include a strap or tie and is sized to hold (and apply a force to maintain) a portion of the physiological monitoring garment (eg, sensor / electrode) against the user's body. Can be set. Also described herein are integrated into these devices to apply a force to keep one or more sensors on the garment firmly pressed against the subject. It is a structure. Such integrated devices are sometimes referred to as integrated support structures. In some embodiments, the support structure is a self-expanding structure. In particular, the integrated support structure may be an expandable (including “expandable”) element. Examples of the support garment and the support garment portion are shown in FIGS.

  Supporting garments (eg, harnesses) can be separated from the compression garments described herein, or can be fully or partially integrated into the garments. The support garment and / or the integrated support structure (expandable support structure) can be sized and shaped to fit the user's anatomy. For example, the support garment and / or support structure can be designed to fit the anatomy of the wearer's chest. The support garment can be sized and shaped based on the gender of the wearer. For female wearers, the support harness can be designed to hold a support structure between the patient's breasts. Examples of combinations of support harnesses and support structures that can be used for support garments are shown in FIGS. 14-14D and 15A-15C. For male wearers, a support strap can be used instead of a harness. Examples of male support straps and support structures are shown in Figures 16A-16C and 17A-17C.

  14A-14B show the support garment 1405 from FIGS. 14C-14D worn on the physiological monitoring garment 1401 shown in FIGS. 13A-13B. Additional support structures (integrated in monitoring garment 1401 or support harness 1405 in this example) may also be used. In this example, the support garment is shaped as a harness or sports bra type configuration to securely hold the second support structure 1403 against the wearer's chest and sternum. 15A-15B illustrate an expandable (eg, inflatable including self-expanding) support structure that can be used for female wearers. 15A-15B, the support structure is shown in front and side views in a non-expanded configuration and an expanded configuration. FIG. 15C shows the support structure of FIG. 15A engaged to the female breast. The illustrated support structure is inflatable and is shaped to engage the female breast to hold the sensor on the smart garment securely against the wearer's breast.

  18A-18B show the support garment from FIGS. 16A-16B worn on the physiological monitoring garment shown in FIGS. 13A-13B. FIGS. 16A-16B show a support strap 1601 having an optional rigid material at the front and an adjustable back material that can be made of a stretchable material and can include Velcro®. 17A-17B show a support structure that can be used for female wearers. 17A-17B, the expandable support structure is shown in front and side views in a non-expanded configuration and an expanded configuration. FIG. 17C shows the support structure of FIG. 17A engaged to the male chest.

  The support structure shown in FIGS. 17A-17B and 15A-15B is for improving electrical contact between the sensor and the chest by compressing the sensor on the physiological monitoring garment against the chest of the body. Provide inward force. In some embodiments, the support structure can be expandable (including but not limited to expandable) to provide a desired shape for contacting the monitoring garment. In some embodiments, the support structure can be self-expanding. A self-expanding material can be used in the support structure so that the support structure automatically expands upon activation. In some cases, the self-expanding material can be realized by a foam material in the support structure and / or by a chemical reaction. In some cases, a chemical reaction can produce a gas or other material that can expand the support structure to conform to the anatomy of the patient's chest. In some variations, the support structure is a local pad or compressible material that can be held by a compression garment and / or a support harness.

  In some embodiments, the pressure applied by the support structure can be selected by the user.

  In some embodiments, the support garment and support structure can include sensors and control systems to provide a desired pressure level to the physiological monitoring garment.

  Supporting garments, such as harnesses, straps, bras, etc., can include velcro, adjustable straps and other adjustable parameters that allow the wearer to improve the electrical contact of the chest sensor / electrode The harness can be tightened to provide the desired fit and support to do.

  In some embodiments, the support garment and support structure can be in electrical communication with a physiological monitoring garment and / or an external computing device.

  The support garment can be used with any of the physiological monitoring garments disclosed herein. In some embodiments, the support garment is used with a compression shirt and pants having the wiring shown in FIGS.

  Returning now to FIGS. 18C-18E, including a sensing device 1801 configured as a compressed garment as described above (eg, for detecting ECG as shown in FIGS. 2A-2B, 3A-3B and 4A-4B). The system can be worn directly against the patient's skin. A support structure (eg, pad, expandable support member) 1805 may be used with the compression garment of the sensing device 1801. The support structure may be placed over the central chest region to apply pressure to hold the electrodes integrated on the inner surface of the garment in place with respect to the skin. The support structure may be expandable (eg, expandable), which allows it to be used comfortably and effectively with a variety of user body types. In some variations, additional support garment 1811 can be used to help secure the electrode (and in some variations support structure 1805) to the skin. The support garment 1811 in this example shown in FIGS. 18D (front view) and 18E (rear view) includes a pair of straps that fit over the shoulder and a central area that can be pressed against the electrodes of the sensing device. It is the harness which has. This support garment may include a plurality of relatively rigid regions 1815 connected by relatively elastic regions 1817. 18F (front view) and 18G (side view, in an expanded state) show enlarged views of a support structure 1805 having exemplary dimensions. This support structure can be attached to the outer or inner region of the sensing garment to help keep the electrode pressed against the subject's chest, while not interfering with measurements from the electrode. In some variations, the support structure is integrated into a harness (supporting garment) such as that shown in FIGS.

Wearable system for emotion detection Also described herein is a garment configured to determine a wearer's emotional state. Self-reported emotional states tend to be inaccurate and subjective, limiting their use. An objective emotional state of the subject can be determined using clothing that may include sensors for detecting various parameters (both optional and involuntary parameters).

  The garment is described below and for detecting a plurality of sensors as illustrated in FIGS. 8A-8B showing a collar that can be included as part of the garment and a parameter indicative of the wearer's emotional state. And a plurality of sensors (which may be included or omitted). Sensors include, for example: environmental sensors (detecting environmental temperature, humidity, etc.), one or more cameras for visual detection including light level / intensity, (eg detecting user's voice volume, tone, etc.) Sound detector. The collar may include any of the other sensors (motion sensors, position sensors, acceleration sensors, etc.) described herein and incorporated by reference. In addition, the collar may include one or more outputs (haptic outputs) for providing the wearer with outputs including feedback. Examples of the haptic output include an olfactory output (aroma release), a tactile output (vibration, a knob, etc.) and the like. The collar described herein and illustrated in FIGS. 8A-8B may be configured as an emotion communication receiver (ECR).

  Any garment for detecting / monitoring emotion may include ECR. The ECR may be placed around the neck. In FIGS. 8A-8B, the ECR is a collar that extends from the back, extends above the left and right trapezius, extends to the left and right sides of the front side of the neck, and is reconnected at the front. This facilitates “sliding” the head through the “device” collar. Receptors in the ECR (collar) can house communication / analysis modules (sensor modules) and connectors (eg female and male connectors) and sensors, haptic activators, and pressure, vibration, temperature changes, tension & relaxation A mechanism for generating input, auditory input, etc. may be included. The front side of the activator also stores odors and tastes that trigger the determination of the quality of the environment by the activator and environmental sensors.

  The ECR may convert the received physiological measurement communication into a physically materialized message. As an example, a friend can send a device user (wearer) his emotional state measured on his device: the user's ECR greets this communication by applying pressure to his shoulder. May be converted into a perceptual message. Users may exchange perceptual messages such as greetings touching the shoulder, hugging, pushing, punching, cheering, relaxing, etc., and: i) ignore; ii) accept and return greeting (with their own message); iii ) You may have a response option including rejection (discharge). The user can choose how to receive the message: a) pressure (wide), b) pressure (narrow, stinging), c) pressure message (like Morse code), d) vibration, e) temperature change, etc. (Including combinations of these). The user may also choose not to accept “emotion” value messages to protect their privacy and / or provide feedback to improve the accuracy of the emotion-interpretation language.

A system for detecting, interpreting, transforming, communicating and recognizing emotions (DETECTION, INTERPRETATION, TRANSDUCTION, COMMUNICATION, AND PERCEPTION OF EMOTIONS: “DITCRE”) For example, the garments described herein (including collars, shirts, etc.) , Can be configured as DITCRE clothes. The schematics shown in FIGS. 9-10E illustrate how the DITCRE can be implemented in a garment including a collar as shown in FIGS. 8A-8B.

  Feedback can be controlled using clothing adapted to detect, deduct and / or determine (acquire) emotional state and perform actions based on the acquired emotional state, which may be a training, meditation or task Can be useful for learning and can also be useful in communication with others. Therefore, an output can be provided using the acquired emotional state, which can generally be obtained over time from analysis of multiple sensors worn by the user. Such communications are generally more reliable, partly because the interpretation of emotional states is based on detected parameters rather than self-reported parameters alone and the use of different sensing modalities. Can be high and detailed. The wearer can choose when and / or what emotional state they want to communicate with and especially with whom they want to communicate. Any of the garments may include one or more outputs (eg, haptic outputs) detected by the wearer as described above. For example, haptic coding may be used to communicate without having verbal / written communication. For example, Morse type codes may be used to transmit haptic coding to / from the wearer. In general, a haptic activator may be located in a body region / location (which is determined empirically for a particular user or generally from a set of multiple users) with the strongest sensitivity and emotional response. Optimizes the position of the haptic activator.

  Thus, the garments described herein can add additional dimensions, especially during communications, including communications between wearers. For example, the body “language” can be interpreted by the sensor module and can feature output from clothing or communication from clothing. The garment may also be adapted to provide comments that may have feedback, therapeutic effects on the wearer (including identifying and treating depression, etc.).

  In use, these garments can also provide an interpretation of the subject's emotions and an output representing it. For example, the garment can support interpretation across multiple cultures / languages. Similar to the presence of spoken language, non-obvious communications (gestures, body language, etc.) can also provide cues that the device can use to express as part of the subject's output or that can be received by another user.

  As described above, in FIGS. 8A and 8B, the collar is placed around the neck, which extends from the back, above the left and right trapezius muscles, and to the left and right sides of the front side of the neck. And not necessarily reconnected at the front, which facilitates "sliding" the head through the collar. The receptor is a sensor management system (SMS), female and male connectors, and sensors (eg: EMG sensors on the left and right trapezius muscles as additional parameters for assessing the user's emotions such as the level of stress or relaxation) An olfactory sensor as an additional parameter for evaluating the user's emotion; an environmental sensor for determining the quality, toxicity, etc. of the surrounding environment), a haptic activator, and a mechanism for generating pressure, vibration, temperature changes, etc. May be stored. These sensors can communicate a user's or other user's emotions and can convey relaxation and tension inputs to the user as "messages" or relaxation treatments.

  In some variations, the garment also includes one or more olfactory sensations arranged as an additional means for communicating a user's or other user's emotional state on the front left side and front right side of the ECR. Can be adapted to determine facial expressions as activators (e.g. fragrance & odor regeneration activators) and taste activators, and additional parameters for assessing other person's emotions and / or for assessing the environment Also includes one or more cameras (eg, located on the right or left front side of the ECR). The collar may also include speakers for sharing music and messages with people around.

  The ECR can be connected by the touch points described above (intentional touch areas on clothes) and can be activated and managed. The ECR may receive input from the sensor management system that includes an assessment of the user state translated into two or more emotional values or states (eg, eight emotional states). The number and classification of such states can change in the future. Examples of emotional values include: acceptance, anger, expectation, disgust, joy, fear, sadness and surprise. The emotional value can be communicated back to the user and / or to a third party (in accordance with the user's control). Emotional valence can help users better understand their emotions and can help communicate their emotions to friends in a shared category.

  ECR is generally a physiological measurement (eg, ECG, skin conductance, EMG, breathing, etc.) and “evaluation” (eg, facial expression, posture, gesture, motor behavior, voice tone, eye-drowsiness or arousal, exercise, behavior, etc. ) Can be converted into clearly quantified emotions. The EMG can also assist in communicating these emotions by voice, physically materialized messages or visual displays. As an example, a friend can send an emotional state measured by his clothing, and the user can send this communication: a perceptual message (such as a greeting by applying pressure on the shoulder); a friend's emotional state emitted as a haptic Odor or taste explaining the color; a color explaining the emotional state of the friend; or a voice or visual description of the emotional state of the friend. Users may exchange perceptual messages such as greetings touching their shoulders, hugging, pushing, striking, cheering, relaxing, etc. and may have a response option. For example, the user may ignore, accept (with a unique message) and return a greeting, and / or reject (discharge). The user can also specify how to receive the message: a) pressure (wide), b) pressure (narrow, stinging), c) pressure message (like Morse code), d) vibration, e) temperature change, f) Voice explanation, g) Visual explanation, etc. The user may control the exchange of communications and may choose not to accept “emotion” messages to protect their privacy. This communication modality (including the use of haptics) is more effective when other modalities that are not limited to auditory or visual (by speaking / writing) modalities, such as touch, communicate emotional content / context ( (Or have different effects). Thus, any of the garments described herein can convert a user's physiological measurements into a clear communication, including a communication of the user's emotional value. The user may select a communication data format (for example, different forms of touch, voice, graph, diagram, number,...). For example, with clothes, the user can measure the user's physiological measurements (emotional value), voice to other users, physically materialized messages or visual displays (on the forearm, on glasses or on a display or touchscreen on a smartphone) ). In addition, clothing and particularly clothing with ECR can improve the accuracy of the emotion-interpretation language by allowing the user to provide feedback in data evaluation, rendering and communication.

  The ECR system can also function as a self-improvement system (almost like the state-of-the-art speech recognition system), and when users express and communicate more of their emotions, emotion quantification, explanation and communication become more Become accurate. In addition, the user can activate and interact with the system through touch points on the clothing.

  ECR can be used in a variety of contexts. For example, ECR can be used as a lie detector. Typically, lie detectors detect changes in body function that are not easily controlled by consciousness, which may include body reactions such as skin conductivity and heart rate. The lie detector also considers respiratory rate, blood pressure, telangiectasia, and muscle movement. These measurements may indicate a short-term stress response that may be due to lying or importance to the subject. Problems arise because they are also related to mental effort and emotional state and can therefore be influenced by eg fear, anger, surprises, etc. The EDR system described herein can be used for long-term monitoring and training / adjustment of users, which can better distinguish responses such as those described above from artifact responses.

  ECR is a safety assessment such as environmental safety, air (contamination, level of toxicity, etc.), water (does not drink, cannot swim, etc.), soil inspection; site inspection, for example, risks in the surrounding area, Search for crime reports, avalanches, floods, tree drops, toxic areas, etc .; can also be used to indicate events such as regular events such as parades based on time of day, time of day, etc. The ECR can also monitor user behavior and provide data / feedback regarding the behavior (eg, eating, drinking, drug abuse, etc.). Garments with ECR can also support driving such as machine / vehicle driving (driver behavior, driver performance, surrounding traffic, road type, weather conditions), flight, sailing or other operations and / or above Provide feedback on driving.

  Finally, garments with or without ECR can be useful for safety actions: a) emergency calls: 911, physicians, GPS tracking, family monitoring / tracking, coaching; b) types of dangers, Providing relevant information such as location, user physiological data, user medical and related data, user emotion data, health insurance, financial profile, etc. Clothes (with or without ECR) may also be more interactive and provide health suggestions, including activity levels, diet, etc., or emotional health.

  As described in FIGS. 10A-10E, ECR is: physiological information (measured by sensors), gestures (eg wrist IMU and accelerometer), posture (eg modules, each shoulder, mid-vertebral, lower spine) IMU), motor behavior (eg IMUs for each ankle and wrist), speech evaluation (eg voice recording), facial expressions (eg ear, forehead and neck sensors for self, video for others) Measurement and evaluation based on one or more of (camera), odor or odor (eg chemical sensor), EMG and / or EEG sensor, and / or environmental assessment (eg temperature sensor, contamination sensor, etc.) Can be implemented.

  For example, FIG. 9 is a schematic diagram of a pair of users each capable of interacting with clothing adapted for emotion detection, interpretation, transformation, communication and perception. Each of these regions (labeled A to D) is shown in FIG. 10A (detectors, including sensing devices), 10B (interpretation of sensor data to determine emotional value), 10C (actuator and user or Further details are shown in 10D (Feedback), as well as 10D (Feedback).

  Such devices can be used by populations, including people interested in monitoring their health during daily regular activities (walking, eating, working, sitting in front of a computer ...) Applications may also be found for athletes who want to monitor their fitness level during training or specific sports. Participants (users) may need to fill in a list similar to what is registered and filled in at the hospital or similar to what professional athletes fill out. The more people involved answer more questions, the more accurate the assessment.

  FIG. 10E illustrates one method that can determine emotional values for a particular user based on various sensor inputs and can also include feedback specific to a particular user. Further, FIGS. 11 and 12 show an illustration of how ECR can determine an actual emotional value or an overall estimate of “being healthy” from a subject (FIG. 11). Similarly, the sensor can be used to provide the user with an overall fitness indicator (FIG. 12). These charts can provide an assessment that can be presented as a diagram as shown in FIGS. 11 and 12 and provide a snapshot of an individual's health or athlete fitness level. The assessment may be based on a number of parameters (eg, this can vary from 8-20 or more depending on the number of sensors in a given device). Each illustration can provide: (1) a value that combines the user's health or fitness level based on an adjusted synthesis of all parameters; (2) whether it is above or below the average (3) Individuals, which is a composite of the health status or fitness level of the entire set (given as an absolute number and% of the number) (the accuracy of this value increases with the number of users) You can adjust the above values for your specific needs. For example, because 70% of people over the age of 65 are lit and injured due to lack of balance, the balance of 70-year-old individuals may be given a higher relevance than a 40-year-old. Similarly, weightlifting player strengths that are self-evident may be given a higher degree of relevance than tennis players, or durability may be given a higher degree of relevance for super triathlon athletes than slalom skiers. Thus, the user can use this type of graphical output to see his value and the entire set of values for each parameter. The user can further proceed to details regarding each parameter. For example, efficiency score compared to the efficiency score of the set; method of calculating efficiency: biometrics involved in the calculation; accuracy of calculations taking into account the current state of the art; medical accuracy, etc.

  A user who chooses to improve a given parameter (e.g., balance feeling for 70 years of age) may be given a list of exercises (jumping rope, standing on one leg, etc.) to do this. Using haptic feedback, users can be informed of their balance feeling below or above average and / or an indication of improvement and / or a contrast between the session performance and the individual's best performance .

  Numerous sensors and haptic actuators in the device allow one user to interact with other users to maximize their efficiency during their movement and improve their achievement (e.g. through voice, haptics or visual messages) ) May be adapted to allow communication. For example: a) The athlete is not warming up at the start of exercise; b) The temperature is too low at the end of the exercise; c) The posture or position is not appropriate when performing the exercise; d) The user has his muscles E) Communicate if the athlete is not fully loaded during the training session.

Stretchable conductive ink pattern Any of the devices described herein may include a stretchable conductive ink pattern. In general, the stretchable conductive ink may have a stretchability in the range of 5% to 200%, and can be stretched without breakage, for example, more than twice (200%) the length of the stationary state. In some examples, the stretch conductive ink can stretch to more than 3 times (300%), 4 times (400%) or 5 times (500%) its neutral, standing length. . The stretchable conductive ink pattern is conductive and has a low resistance. For example, the bulk resistance may be 0.2-20 Ω * cm (and the sheet resistance may be about 100-10000 Ω / □). The conductivity can depend on the stretch, but can remain within the above range (eg, 0.2-20 Ω * cm).

  Structurally, any of the stretchable conductive ink patterns described herein are typically made from a specific combination of insulating adhesive and conductive ink. In general, a stretchable conductive ink pattern includes a first (or base) layer of insulating and elastic adhesive and a layer of conductive ink, the conductive ink being about 40% to about 60%. Conductive particles (e.g., carbon black, graphene, graphite, silver metal powder, copper metal powder, or iron metal powder) and a gradient region between the insulating elastic adhesive and the conductive ink layer. The gradient region is a combination of conductive ink (eg, conductive particles of conductive ink) and an adhesive, and the concentration of ink (eg, conductive particles) can vary with depth. In general, the gradient region may be a mixture of conductive ink (eg, conductive particles) and an adhesive, and the concentration of the conductive ink in the gradient region is less than the concentration of the conductive ink in the conductive ink layer. It's okay. The gradient region may be a continuous gradient of conductive ink (particles), for example, the gradient region may be non-uniform or a stepped gradient.

  Typical conductive inks, such as those used for printed circuits and also for flexible circuits, are sufficiently stretchable for use for garments, especially for compression garments. Rather, it may break during use or form a discontinuity. Surprisingly, the combination of conductive ink, gradient area and insulating adhesive provides a conductive and highly stretchable / expandable conductive ink composite. The composition of conductive inks that can be used as described herein generally includes: about 40-60% conductive particles; about 30-50% binder; about 3-7% solvent; and about 3 Contains ~ 7% thickener. Furthermore, the use of an intermediate “gradient” region between the insulating adhesive and one or more conductive ink layers has also been found to be important.

  Conductive inks used to form conductive ink patterns and used in conjunction with adhesives typically have low toxicity and low allergenicity (eg, less than 100 ppm formaldehyde concentration) and resistance to damage from laundry And the resistance includes preservation of electrical and elastic properties after repeated washing cycles.

  FIG. 39C shows a modification of the conductive ink pattern (conductive ink composite) having a high degree of extensibility or stretchability. In this example, the conductive ink pattern is applied onto a substrate 1039 (which may be a compressed garment or a fabric comprising a compressed fabric that forms a transfer substrate) and a first layer 1021 of electrically insulating elastic adhesive. including. The outer layer 1025 of conductive ink is separated from the adhesive layer 1021 by an intermediate gradient region 1023 that is a mixture of conductive ink and adhesive, and the concentration of the conductive ink is a region close to the layer 1025 of conductive ink. To the elastic adhesive layer 1021. This gradient region may be referred to as an intermediate layer and may have a non-uniform mixing / distribution of conductive ink and adhesive. An optional outer insulator (eg, an insulating resin not shown) may also be included to cover the conductive ink layer. The outer conductive ink can be formed from multiple layers of conductive ink.

  For example, FIGS. 39A and 39B show electron micrographs (scanning electron micrographs, SEM) of a sample of a conductive ink pattern placed between two aluminum supports. In FIG. 39A, the lowermost layer 2805 is an adhesive, the layer adjacent to the upper side of the layer 2805 is the gradient region 2803, and the layer adjacent to the upper side of the layer 2803 is the conductive ink 2801. In this example, an additional insulating layer (resin 2811) is disposed on the conductive ink. In general, conductive ink can be formed of multiple layers of applied conductive ink. In FIG. 39A, the conductive ink layer was formed by sequentially applying five layers. These layers are not visible in the micrograph.

  In FIG. 39B, the layer thickness was quantified using electron micrographs. In this example, the thickness of the conductive ink layer 2801 (region) is about 50 μm, the thickness of the gradient (transition) region 2803 is about 40 to 80 μm, and the thickness of the bonding agent 2805 is about 150 μm.

  The gradient region can perform both functions of enhancing the stretchability of the conductive ink and enhancing the stability of the conductivity. Conductivity is enabled by the upper region, while the high degree of mechanical stretch enabled (by the adhesive) is enhanced by the lower layer. Incomplete mixing of the conductive ink and adhesive found in the gradient region is believed to result in a structure and composition that can be repeatedly stretched and released while retaining conductivity. Note that the resistance of this complex can vary with stretch (generally resistance increases with stretch) and this property can be used to detect stretch.

  In general, the gradient region can be formed by combining the conductive ink and the adhesive before either one is completely dried to form a transition region of appropriate thickness. The composition of the ink (eg, about 40-60% conductive particles; about 30-50% binder; about 3-7% solvent; and about 3-7% thickener) Formation parameters can be determined. 40A to 40D show examples of composition distributions of examples of stretch conductive ink patterns (composites). In FIG. 40A, carbon is shown, which is ubiquitous throughout the layer, as expected for organic materials. In FIG. 40C, the distribution of silicon is concentrated on the surface of the base material (plastic base material on which the conductive ink pattern is produced) and diffuses in the conductive ink pattern. Similarly, in FIG. 40D, oxygen is diffusing everywhere. In contrast, as shown in FIG. 40B, sulfur is concentrated in the ink but not in the binder. Thus, the sulfur gradient shows a gradual transition from ink to binder in regions that are morphologically similar to binder. This region is a gradient region where non-uniform mixing occurs.

  In FIGS. 39A-39B and 40A-40C, the stretch conductive ink pattern is formed on a polyester paper substrate, and the ink and adhesive are printed on the substrate (along with the outer insulating resin). This pattern may then be applied to the garment so that it adheres to the garment and the substrate (paper) can be peeled away so that the ink remains. The adhesive has high elasticity and is stretchable. The conductive ink alone may have some stretch properties, but probably not as stretchable as adhesive due to the rigid metal particles. The middle region (where the adhesive and conductive ink overlap) is important. By thoroughly mixing in this region, this region becomes uniform and the conductivity may decrease (because the adhesive is insulating). When the mixing is partial, the stretchability can be maintained while the conductivity is maintained.

  An outer protective layer that insulates the conductive ink may be included where it is desired, e.g., when forming conductive traces, or when patterning a sensor or electrode, but the contact area of the electrode is It may be left without a layer. The resin (“primer”) may be one or more layers of insulating material that does not link or mix with the conductive ink. For example, the resin material may be insulative and may assist in protection from detergents and fluids (water) used for washing, as well as protection from scratches and the like. In some variations, the resin is an acrylate (eg, an acrylic resin). Aldehydes or acrylics (synthetic resins) may also be used. Any of the components (eg, conductive ink, adhesive, and resin) may be applied by printing. For example, FIG. 41 shows an example of a method used to print a stretchable conductive ink pattern on a substrate. In FIG. 41, a first mask (“screen”) 3001 is used to form a pattern of an adhesive (conductive bonding agent) applied to the substrate on the lower side (not shown) of the screen 3001. For example, when applied directly onto a fabric, the adhesive is pulled by pulling the adhesive 3005 across the screen so that the “wet” adhesive 3005 forms the pattern shown in the screen printing process. May be applied. The adhesive may be applied multiple times, or the thickness may be adjusted in other ways (eg, by application force, viscosity, and / or screen opening size). Thereafter, a conductive ink pattern may be applied using a second screen (or the same screen). By applying the conductive ink multiple times, the desired thickness (typically less than the thickness of the adhesive) can be achieved. The second screen may have slightly smaller openings than the pattern used for the adhesive, or may be the same size (or larger in some variations). The adhesive and the conductive ink may be in the same range. When applying to the transfer substrate, the above order may be reversed, and the conductive ink may be applied to the substrate before the adhesive. As described above, the insulating resin (eg, protective layer) may be applied adjacent to the conductive ink layer.

  In some variations of the conductive ink structures described herein (eg, traces, sensors, etc. formed with conductive inks, eg, by direct printing and / or transfer to a fabric), the conductive ink is , Carbon black, coated mica (eg, mica coated with antimony-doped tin dioxide), graphene, graphite and other conductive particles. The material may also include a base / bonding material that functions to permanently bond all solid components contained in the ink to the fabric. This binding material (binder) may be acrylic-water based, for example water based polyurethane. The conductive ink material may also include a primer, which increases adhesion and compatibility between the various products applied and increases resistance to the laundry process. The conductive ink may include an adhesive (eg, an adhesive such as acrylic or polyamide) that ensures transfer of the conductive product to the fabric. Any of these conductive inks may also include a defoamer to eliminate air and bubbles contained in the product, and a catalyst that can completely crosslink the binder. Additional additives may be included to increase the printability and stability of the product. A thickener that increases the viscosity of the liquid component contained in the product may also be included. The transfer of the resulting ink material can be obtained by a silk screen printing process as exemplified above. For example, a silk screen printing process may include a serigraphy frame type (24-120 wires) and transfer support films such as paper, cardboard, polyester, acetate, reflectors and the like. The number of screen printed / applied layers may be 1-50 or more. The order of the applied layers can be continuous (and can be reversed as the material is transferred). For example, a primer may be applied next to the last layer and the adhesive is the last layer formed. The conductive ink may be dried by, for example, an IR oven, a hot air blower, or a cold air blower. As mentioned above, this ink material (including adhesive base) can be any suitable material including, for example, cotton, wool, nylon, polyester, polyamide, lycra, leather (natural or synthetic), plastic film, ESD fabric, etc. You may apply to.

  The ink can be applied by transferring it to a fabric using a thermocompression bonding machine by applying a coating pressure of 2 bar to 90 bar over a coating time of 5 seconds to 50 seconds at a coating temperature of 100 ° C. to 250 ° C., for example. . The final polymerization can be carried out in an IR oven at a temperature of 50 ° C. to 180 ° C. (for example using a conveyor belt speed of 0.1 m / sec to 5 m / sec).

  As described above, the conductive ink patterns described herein can be traces (eg, connecting various elements on a garment), sensors (eg, touch point sensors, stretch / breathing sensors) or electrodes (EEG sensors, ECGs). Any suitable pattern including sensors, EMG sensors, etc.). When used as a connector, the conductive ink pattern may include additional conductive, including but not limited to conductive threads, stitched zigzag connectors, conductive traces formed on a substrate such as Kapton, and the like. May be used in combination with a flexible connector element. Such a combination of a conductive ink pattern and an additional highly conductive material can be particularly useful at relatively long lengths. In some variations, the stretch conductive ink material may be used as a trace or connector in an area that would cause the garment to stretch significantly.

  For example, FIGS. 42A-42C show examples of conductive threads sewn into a garment forming fabric, which is formed of a stretchable conductive ink pattern (with adhesive, gradient area and conductive ink). It can also be used as an electrode, sensor or trace to a power supply and / or sensing module.

  For example, in FIGS. 1A-1F, 2A-2B, 3A-3B, etc., the touch points and the traces connecting them to the sensor module (sensor manager) include an adhesive layer, an intermediate gradient region and a layer of conductive ink. It may be formed of a stretchable conductive ink composite that includes it, and the trace portion may be insulated using, for example, a protective resin. The electrodes forming the touch point portion can be relatively large and the connecting traces are relatively small. The trace need only extend a short distance. Touch point sensors are also somewhat insensitive to clothing / trace stretches that can change the resistance of the trace because the signal from the sensor is a binary signal (eg, touch or no touch). Similarly, stretch conductive ink traces (composites formed into traces) may be used to connect to the EKG electrodes. Typically, the conductive ink pattern used as the trace may extend to less than 30 cm (eg, less than 25 cm), but longer traces may be used. Thus, for example, a conductive trace formed with a stretchable conductive ink pattern may be as long as 25 cm or longer, with a width of 2 mm to 10 mm (average of about 0.6 to 0.5 mm). The length can be extended while maintaining the targeted conductivity / resistance range by increasing the thickness of the conductive ink pattern. In some variations, it may be desirable to keep the length short. However, the respiration sensor can be substantially longer, for example the width can be up to 22 mm.

  In some variations, it may be useful to use conductive threads or other highly conductive connectors, such as those shown in FIGS. As described above, this can be used to form a sewn zigzag connector (also referred to herein as a wire ribbon material). In this example, the conductive threads are sewn to the garment in a wavy (eg, zigzag, sinusoidal, etc.) pattern, which allows some stretch in the net direction of sewing. As described above, a breath (sensor) trace can be formed with a stretchable conductive ink pattern to take advantage of a change in conductivity due to a change in resistance due to stretching of the conductive ink pattern. In this example, the stitched thread pattern includes a roughly 35-40 ° zigzag pattern that allows the seam to stretch slightly with the fabric. In some examples, the conductive thread is a metal conductive thread. The angle formed at each inflection point (of the wavy pattern) and the width of the pattern can depend on the textile used. In general, the higher the textile stretch properties, the smaller the angle. The number of threads may vary, and in general any number of threads may be used, for example depending on the number of sensors and the number of pins of the sensor that need to be connected. The thread is typically sewn directly into the garment. The electrical insulation of the thread can be obtained by an outer coating on the thread (eg silicone, polyester, cotton, etc.) and / or by a layer of insulating adhesive as described above. The thread connector may also be used as part of the transfer substrate as described above. For example, the conductive thread may be sewn to a band made on the same fabric as the garment and then transferred by a thermal process on the garment, for example using a layer of adhesive.

  One or more conductive threads can be applied directly to a fabric (such as a compressed garment) or to a transfer substrate (eg, a patch of fabric or other material that is subsequently attached to the garment). The conductive thread may be insulated (eg, enameled) prior to stitching. In some variations, the conductive threads may be grouped prior to sewing to the fabric or other substrate. For example, a plurality of threads (for example, 2, 3, 4, 5, etc.) may be insulated and wound together and then sewn on a base material such as a compressed fabric. For example, in one variation, the device includes a garment having an IMU included on the sensor module / manager and two EMGs with inputs supplied to circuitry (eg, a microchip) on the device. These components can operate on the same electrical “line”, which is a plurality of conductive threads combined together for sewing to a substrate. In one example, two microchips can be operated by the same “line” of four wires, where each wire is electrically isolated from each other. In the sewing of material, as understood with respect to mechanical sewing devices, the seam may be formed of two sets of wires, one on the top of the substrate and the other on the underside of the substrate. In a variation, the seam formed of conductive threads may include an upper conductive thread (or group of conductive threads) and a lower conductive thread (or group of conductive threads), where In which one or more upper conductive threads are initially on the upper surface and one or more lower conductive threads are initially on the lower surface (although one or both of these engage the other) In order to penetrate the substrate).

  For example, a conductive thread consists of four twisted, enamel-coated (and thus electrically insulated from each other) wires coated with a binding solution (silicon or water-based) or protected with a jacket , Which may include very thin (eg, 0.7 millimeter gauge / thick) “wires” having a total diameter of about 0.9 millimeters. The conductive wires may be sewn directly to the fabric or substrate in a wavy (eg, zigzag) pattern, such as a pattern having an angle of 45-90 ° between the zigzag legs. In some examples, the pattern is formed on a substrate of material (eg, a fabric) and attached to a garment. For example, the substrate may be a self-adhesive strip of 1 cm to 3 cm woven fabric.

Sensor Manager / Module Any of the devices described herein (eg, garments) may include a sensor manager (SM or SMS) as schematically illustrated in FIG. 43A, which includes electrodes (including electrodes etc.) ) Connect the sensor to a processor, which in some variations includes a smartphone or other mobile device. The sensor manager is part of a compression garment with a sensor (eg a shirt) and is placed on the back of the shirt, eg just below the neck as shown in FIGS. 1B, 2B, 3B and 4B (as shown in FIG. 43B). It may be a printed circuit board (PCB) that can be embedded in a rigid case. This mainly serves to collect and scrutinize data coming from sensors located throughout the shirt.

  As shown in FIG. 43A, the PCB that forms the sensor module 3201 includes different elements disposed on the PCB, such as a microcontroller 3203 (eg, CY8C5 microcontroller (68 pins)), and a telephone module 3205 (metal coating). Drills), tights 3211 (exposed solderable metal area) and sensors 3207, 3209 (connection with sleds).

  For example, an electrical signal coming from a sensor can be carried by a conductive thread that is sewn to a fabric of a shirt or to a tape (eg, a patch) made of the same material. These threads can all lead to the SM PCB and can be connected to the SM PCB using a connector or can be sutured / soldered around a metal coated drill. In contrast to the SMS illustrated here, the SM architecture with sensors connected directly to the telephone module involves a relatively large number of pins 3205 (eg, one for each trace / thread coming from the sensor). This may limit the number and type of sensors and may compromise on system stability. With the architecture described herein, traces (eg, threads) coming from the sensor can be directly connected to the microcontroller using different types of connections (eg, 3207, 3209) that can be placed on the SM PCB. In this way, all sensor signals can be collected (collected) by the microcontroller, which then processes the processed data using only two pins 3205 for holding digital UART communication, It will communicate to the mobile processor (eg smart phone) module. This solution does not limit the type or number of sensors.

  As shown in FIG. 43A above, this schematic shows a female connector for a usable mobile processor (eg, a smartphone). In this example, a sensor management system (SMS) can be placed in the garment rather than on the module / phone. Therefore, even if the number of sensors differs between clothes or accessories, the number of pins remains constant. For example, the number of pins can remain constant (eg, 10-15) by adapting a particular SMS to comprehensively cooperate with different mobile processors (telephones).

Experimental Data A garment configured to monitor physiological parameters including 12-lead ECG detection and respiration was made as described above. The body of the garment is a compressed fabric (formed of compressed fabric material) with 10 ECG electrodes (6 on the chest, 1 on each arm and 1 on each leg), as shown in FIG. 2A or 3A. Arranged as shown. In addition, a respiration sensor was included that was formed of a conductive particle impregnated elastic material and placed near the diaphragm when worn. The subject wore the garment, and the subject also wore a standard electrode for measuring the 12-lead ECG during the activity (stress) test and a mask for measuring respiration through the mouth and nose plugs. In order to help maintain the electrodes in place with respect to the skin even during physical activity, the patient can support the center of the chest (inflatable) and supporting clothing (harness on the shirt) ) Was also worn.

  The patient was required to pedal a resistant bicycle pedal and measured using a standard 12-lead ECG and plethysmography, which was performed using the garment with an integrated sensor as described above. Compared to simultaneous reading. Despite potential interference between standard leads of a (standard) ECG machine worn under the garment, the physiological monitoring garment described herein is a standard (control) device and Works equally well or better.

  For example, FIG. 48A (left side) shows ECG results for six leads (I, II, III, aVR, aVL, aVF) of a standard 12 lead ECG, and FIG. Six leads recorded using are shown. There was an excellent correspondence between the control (reference) device and the garment.

  As shown in FIG. 47A, respiration was also measured from the clothes using a respiration sensor. The garment detected perceptible changes in breathing patterns between baseline, work load (pedaling against increasing resistance), and return from two areas measured by the garment (abdomen and thorax). . A comparison was made between standard plethysmography and the garment and is shown in FIG. 47B. Both techniques measured approximately the same respiration per minute during each section examined.
