Description

  The present invention relates to an electronic fiber or electronic yarn in which various electronic devices or electronic circuits are mounted on the fiber or yarn itself, and a textile product such as an electronic cloth or electronic clothing using the same.

  In conventional electronic devices, a printed wiring board on which a wiring pattern is printed by plating or the like is prepared on a printed board made of glass or plastic sheet, and various electronic components are mounted on the printed wiring board. Those composed of electronic circuits were used. Recently, printable electronics technology has been established in which electronic devices such as transistors and electronic circuits are directly formed on a very thin and flexible plastic film, and a display, electronic paper, etc. using the device are formed.

  For example, a transistor formed by printing on the surface of a plastic sheet, and a conductive ink on a flexible plastic sheet so that it has almost the same function as a conventional silicon substrate. An electronic device such as a transistor having flexibility is manufactured, or an electronic circuit composed of these electronic devices is being realized. As a result, a more compact electronic device can be realized by arranging a flexible plastic sheet printed board on which such electronic circuits are printed in a case (housing) (for example, Non-patent document 1).

  However, it is difficult to incorporate an electronic device having a three-dimensional structure housed in such a case into clothing such as clothes that require flexibility and flexibility. The electronic device is carried around by wearing clothes having a special storage pocket, or is taken out from the storage pocket and used during movement (for example, see Patent Document 1).

  As represented by mobile phones, mobile electronic devices with functions such as computers, audio devices, and information terminal devices are becoming more and more miniaturized, and they can be placed on the body by storing them in clothes pockets. An environment that can be worn and used “anytime” and “anywhere” is being realized.

  The miniaturization of a semiconductor chip is a basic technology necessary for further downsizing the above-mentioned mobile electronic device, and further development of the downsizing technology will be accelerated in the future. Attempts have also been made to put a semiconductor chip typified by RFID (wireless tag) into practical use by attaching it to a cloth, paper, plastic or the like.

  In a biological information monitoring system, for example, a mobile device such as a wristwatch is used, and a sensor for detecting body temperature, blood pressure, pulse, and the like, and a circuit for processing these sensor signals are built in the mobile device. A method has been proposed in which the health condition is constantly monitored and an emergency call is made to a predetermined contact when the health condition deteriorates (see, for example, Patent Document 2).

  Conventional general clothing has no electronic function for acquiring or transmitting information, and is used in a state in which a shape and performance necessary for clothing worn by a person are maintained. For this reason, if an individual needs to acquire or send information at a destination or any other place where they are moving, for example, a portable electronic device must be stored in a bag or a pocket of clothes and held. There were problems such as having to take out and perform necessary operations.

  Functions frequently used by individuals include viewing, listening, speaking, and measuring, but in order to memorize and transmit these information, cameras, speakers, microphones, measuring instruments that have these basic functions It is more desirable to incorporate a plurality of electronic devices, etc., in an optimal place for clothing and always integrate them as part of the individual's body, rather than using them separately. However, since such a conventional electronic device has a three-dimensional shape of a certain size, there is a problem that it is difficult to integrate it with clothes or the like. For this reason, it must be stored and used in clothes pockets and portable bags.

  Regarding a light-emitting device using a light-emitting diode (LED), which is a typical example of a light-emitting device, a method of mounting a panel having a plurality of LEDs on a cloth surface has been proposed. It was accompanied (for example, refer patent document 3). For this reason, it has been difficult to achieve clothing that incorporates multiple LED light-emitting devices and has a rich and unique expressiveness, or clothing that emits unique light and attracts the line of sight from the periphery or from a distance. .

  Since metal foil yarns such as gold and silver can have a unique luster, it is possible to provide colorful fabrics and fashionable clothing. However, since it does not have an electrical function such as a light emitting effect, cloth and clothing made of foil yarn cannot be controlled from the outside, such as external control of color and dynamic change of color information.

  When mobile devices are used, such as mobile devices such as mobile phones and watches, and biological monitors such as heart rate monitors and thermometers for checking the health of individuals, users must collect these information collection devices. You can wear it on your body or store it in a pocket of your clothes, but you are still satisfied with the fact that you can use it "anytime" or "wherever" because it is cumbersome, annoying, or misplaced. It wasn't possible.

  Proposals have been made to attach small wireless IC tags, which have recently been attracting attention, to clothing, etc., but this method also requires tasks such as pasting and removing, and there are cases where it is lost or misplaced. was there.

  Recently, there have been proposed woven fabrics and woven fabrics in which such problems are improved and the woven fabric itself has an electrical function. That is, an electronic yarn named a functional yarn is used for a warp or weft of a woven fabric or woven fabric, and this functional yarn has an elongated substrate, and a conductor, an electronic device, and the conductor and the electronic on the substrate. An electrical contact portion (or connecting means) for connecting the devices is formed (for example, see Patent Document 4). However, since the electronic device is arranged on the substrate formed on this functional yarn, it has a three-dimensional three-dimensional structure having irregularities, and these electronic devices are extremely inflexible, so that weaving, knitting There has been a problem that the function as a normal thread such as embedding and sewing, and the performance of the resulting textile product cannot be fully exhibited. Furthermore, there is a big problem that a joining means such as a conductive adhesive or soldering is required to connect the wiring composed of the conductor on the substrate and the electronic device.

Further, in a textile product such as a woven fabric or a woven fabric, in order to provide an image display function such as a display using a large number of light emitting elements such as LEDs, the light emitting elements are arranged in a matrix and the address of each light emitting element is assigned Must be specified. For this purpose, a means is required in which a large number of conductive yarns are woven or knitted in both the longitudinal and transverse directions of the woven fabric or woven fabric, and used to connect to each light emitting element to supply power and signals. There were issues such as.
JP 2003-13317 A JP 2002-74542 A Japanese National Patent Publication No. 8-511354 JP-T-2005-524783 Nikkei Electronics, December 16, 2004, 94-102

BEST MODE FOR CARRYING OUT THE INVENTION

  The electronic fiber or the electronic yarn of the present invention is obtained by forming one of an electronic device, an electrical wiring, an electronic circuit, or a combination thereof by a fine processing method on the surface of a fiber or yarn made of synthetic fiber or recycled fiber. . Further, the textile product of the present invention is produced by knitting using the electronic fiber or electronic yarn of the present invention as a part of its constituent fibers. An electronic cloth or an electronic garment provided with an electronic device such as As an electronic cloth, for example, a flag, a banner, a bib, a headband, a towel, a tapestry, a wall hanging, a screen, a warm bath, a string made by knitting and weaving using the electronic fiber or electronic thread of the present invention to which an LED is attached. Etc.

The synthetic fiber or recycled fiber used in the present invention is an electrically non-conductive fiber having a smooth surface capable of forming an electronic device, electrical wiring, electronic circuit, or a combination thereof on the surface. I just need it. Using current microfabrication technology, electronic devices, electrical wiring, electronic circuits, etc. can be formed in an extremely small area. Specifically, the fiber surface has a smooth surface of at least 10 μm × 500 μm. If it is.
Examples of the material of such synthetic fiber or recycled fiber include polyester, nylon, rayon, polyethylene, polypropylene, and polyimide. Moreover, the flat foil thread | yarn which is the foil of the fibrous film sheet with the long shape is preferable.

In the present invention, a material in which an electronic device, an electric wiring, an electronic circuit, or the like is formed on the surface of a fiber by a fine processing method is used.
As the fine processing method, a printing method such as an ink jet method, a screen printing method, an offset printing method, a gravure printing method, or the like can also be used. In addition to the printing method, a coating method, an imprinting method, a plating method, a coating method, a discharge method, a sputtering method, a vapor deposition method, a lithography method, etc., or an optimum combination of these methods may be selectively or additionally combined. Similarly, wiring, electronic devices, electronic circuits, and the like can be formed. In this microfabrication, it is preferable that an electronic device, an electric wiring, an electronic circuit, or the like is directly drawn and formed on the surface of a fiber serving as a substrate by the above method.

Taking a long film sheet-like flat foil yarn as an example, a part or all of the surface of this flat foil yarn is regarded as a substrate, and an electronic device, electric wiring, electronic circuit, etc. are formed on the ink jet as follows. Form by law.
FIG. 1 shows an example of an electronic fiber in which an electronic circuit is formed by an ink jet method. In FIG. 1, on the surface of the flat foil yarn 10, the material of the nano fine particles discharged from the fine nozzles is changed by a method of changing the color with a commercially available color printer. Ink jets containing metal ink containing fine metal particles, inks containing metal oxide materials when making passive devices such as resistors 23, and semiconductor inks and insulating inks such as organic materials when making semiconductor devices such as transistors 11. To make an electronic circuit. However, the ink material to be ejected may be selectively changed according to the type of electronic device, and the same place may be printed multiple times to form a multilayer structure. After each electronic device is formed by the above method, a predetermined electronic circuit may be formed or repaired by additionally printing a wiring pattern or the like. In addition, a pretreatment for improving the characteristics as a substrate, such as printing a plurality of times using insulating ink on the flat foil yarn 10 substrate to form a multilayer film structure, is also possible. In some cases, it is necessary to cover the periphery of the printed electronic circuit with a noise removing material in order to remove the influence of the electrical noise that the manufactured electronic circuit receives from the outside. Moreover, you may use the material for electrical noise removal as a flat foil thread material.

In some cases, after printing an electronic circuit on a flat foil yarn, it is necessary to protect the printed surface by coating the printed portion with an insulating paint or water-repellent resin or laminating it.
In addition, parts of electronic device structures and electronic circuits that are difficult to manufacture only by the inkjet printing method described above must include a step that is combined with an optimal method such as coating, plating, coating, imprinting, vapor deposition, or lithography. There is.

  FIG. 2 is an example of an electronic yarn in which LED elements, electrical wiring, and the like are mounted on a flat foil yarn by a printing method or the like. A large number of LEDs 21 are connected in parallel. Electrical wiring for applying a driving voltage of about 3 volts to both ends is printed. The LEDs do not need to be the same. For this reason, when the driving voltage is different, it is possible to additionally print resistance or the like in series with the LED and control the voltage to adjust the emission color, brightness, or the like. As a power source, a solar battery 24, a rechargeable secondary battery 23, a backflow preventing rectifier diode 25 in the direction of the solar battery, and the like are formed by printing. As a result, an external power supply is not required, and the LED can be operated for a long time. Alternatively, power may be supplied from the outside via a connector printed on the tip of the electronic yarn.

The electronic fiber or electronic yarn of the present invention forms an electronic device, electrical wiring, or electronic circuit directly on the surface of the fiber or yarn by a fine processing method.
Such electronic devices include light emitting diodes (LEDs), electroluminescence (EL), semiconductor lasers (LD), phosphors and other light emitting elements, liquid crystals, batteries, temperature sensors, pressure sensors, heart rate sensors, pulse sensors, There are blood pressure sensors, sound sensors, image sensors, position sensors, acceleration sensors, optical sensors, memories, resistors, capacitors, transistors, coils, connectors, switches, etc. Examples of the electronic circuit include a tag integrated circuit, a transmission / reception wireless integrated circuit, and various device drive circuits.

  So far, yarns made of plain yarns such as rayon and nylon as core yarns and covered with twisted gold and silver cutting foils (films) have been commercialized and used for fabrics and embroidery. That is, a round twist, a bellows twist or a garment twisted gold silver thread in which a flat foil thread is wound around a core thread made of a normal thread, an entangled twist or a braided twisted gold silver thread in which a thin thread is entangled with a foil thread. FIG. 3 shows an example of an LED light-emitting yarn constructed by twisting an electronic yarn having an LED that emits light with a conventional fiber material such as nylon or polyester as a core yarn without any gaps in the same manner. Shown in A twisted yarn in which an electronic yarn 30 having an LED 32 is wound around a normal fiber material or core yarn 31 for covering. You may use EL (especially organic EL) which is the same light emitting device as LED. Textile products such as electronic fabrics and electronic clothing produced by weaving the electronic fibers or electronic yarns of the present invention, which are LED light-emitting yarns or organic EL light-emitting yarns manufactured in this way, have the same feeling as conventional fabrics and clothing. Because it can be used in a conventional manner, an effect not seen in the past is exhibited.

  In addition, in an electronic fiber or electronic yarn of the present invention, or a textile product such as an electronic cloth or an electronic garment, a wireless circuit with ID is turned on and off from the outside to each electronic device such as an LED attached thereto. By incorporating or adding a wireless switch that can be used, each electronic device can be arranged independently. Here, the electronic device having the wireless circuit with ID has an electronic circuit for recognizing a unique wireless signal (ID) given to each electronic device, and is recognized by the electronic circuit. The electronic device is turned on and off by a wireless signal from the outside. As a result, not only multiple electronic devices mounted on the same electronic thread from the outside, but also all electronic devices mounted on the same electronic fabric and textiles such as electronic clothing can be operated independently. Remote control. That is, in a textile product constituted by electronic yarns having various electronic devices, the operations of a plurality of electronic devices arranged at arbitrary positions can be freely controlled from outside by radio.

  As such an electronic device, an electronic device having various functions can be used, and a light emitting element such as a light emitting diode (LED) or electroluminescence (EL) is used to emit light in these various states. This is particularly useful in practice.

  As a result, for example, in order to form an image (including a moving image) in a textile product such as a cloth or clothing made of an electronic thread to which a large number of LEDs are attached, the LED is formed on a functional thread as in Patent Document 4. There is no need for a method in which a plurality of conductors are connected to form a matrix. Further, according to the present invention, it is not necessary to electrically connect the LEDs by weaving conductive yarns in the vertical direction perpendicular to the functional yarns in order to designate the addresses of the LEDs arranged in a matrix. That is, according to the present invention, by weaving electronic yarns in only one vertical or horizontal direction and connecting an electronic device such as an LED to this, textile products such as electronic cloth and electronic clothing that can control light emission in various states can be configured. Therefore, a textile product such as an electronic cloth and an electronic garment can be obtained with a relatively simple structure, and the flexibility of a conventional ordinary textile product can be maintained.

  FIG. 4 shows an electronic cloth (screen) 40 in which the electronic yarns of the present invention are woven in the lateral direction and LEDs are formed thereon by a printing method or the like and arranged in a matrix. In FIG. 4, the LED 43 corresponding to the numeral 6 is turned on, but by remotely operating with a computer-controlled wireless device, any LED that constitutes other characters, figures, etc. can be blinked, It goes without saying that a dynamic image can also be obtained by controlling the blinking time between the LEDs.

  FIG. 4 shows an example of an electronic cloth composed of only electronic yarns as weft yarns. However, in order to maintain insulation between adjacent electronic yarns, one or more insulating yarns may be woven between the electronic yarns. desirable.

FIG. 5 shows a schematic diagram of an electronic cloth 51 in which a pattern (mark) that emits light from an LED is arranged at the center, and this is connected to an external power source 52 with a conductive thread. FIG. 6 shows a connection state of the conductive yarn 55 connected to the external power source of the electronic cloth 51 and the electronic devices 57 and 58 such as LEDs.
As shown in FIGS. 5 and 6, a conductive thread 55 or a lead wire connected to the external power source 52 is arranged around the electronic cloth 51 and electrically connected to the connector 56 printed in the middle of the electronic thread 55. Further, electronic devices 57 and 58 such as LEDs can be attached to the tip.

  As shown in FIGS. 7 and 8, by using an electronic cloth with an LED attached as shown in FIG. 4, the electronic thread with the LED attached is only in one of the horizontal and vertical directions. The present invention is characterized in that it can be used clothing or clothes, and various display operations can be realized by freely controlling these many LEDs by wirelessly controlling from the outside.

The above example is an example in which the LED has a wireless function, but other electronic devices such as various sensors also have a wireless function, and it is possible to remotely control each electronic device or obtain a signal. There is no good.
In addition, an antenna or the like necessary for a wireless circuit for performing between the electronic device and the outside may be printed and wired so as to be common to each thread.

  Furthermore, the textile product of the present invention such as an electronic cloth or an electronic garment is not only a woven fabric obtained by weaving or knitting such an electronic fiber or electronic yarn, but also a normal fiber or yarn and these electronic fibers or It may be an electronic non-woven fabric entangled with an electronic yarn, an electronic non-woven fabric in which an assembly of electronic fibers or electronic yarns is bonded by various methods, or a textile product such as electronic clothing composed of these electronic non-woven fabrics.

By using the electronic fibers and electronic yarns of the present invention in which LEDs are incorporated in clothing such as cloth and clothing, these clothing is more attractive and can attract attention from a distance.
As an example, FIGS. 7 and 8 show an example of a T-shirt with a display made by incorporating an LED luminous yarn. In this example, numbers are displayed and can also function as a number tag. The LED is smaller than the electronic yarn diameter and is usually difficult to identify with the naked eye, and is visualized by emitting light.

  The bib number and spine number used by athletes during the match are important landmarks for spectators, referees, and other players watching from a distance. Conventionally, it has been printed on a cloth with magic ink and pasted on the front and back of the player, so it is difficult to identify a player who is agile from a distance. Luminous yarns formed by combining LEDs to form numbers and the like have high numbers and can easily identify the numbers from a distance. In addition, the position of the player can be tracked in real time by incorporating a position sensor such as GPS.

  Similarly to the flag, by making a figure such as a symbol, a picture, or a sign using the LED, the characteristics of the flag can be further increased.

  In addition, it is expected that the effect of being able to be clearly identified even from a distant place is expected by displaying the name tag cloth or number tag cloth to be affixed to the uniforms of the security guards and employees by the character display composed of LEDs. The effect is particularly enhanced at night and in dark places.

  In addition, by combining the LED's dynamic characteristics such as color display and blinking, clothing with a display (Japanese clothes, clothes, etc. and stuffed toys) with a fashionable number, symbol, pattern, etc. that are displayed on the LED. Etc.) can be made.

  Also, when incorporating electronic yarns with LEDs or sensors into clothing such as carpets or curtains where the placement location is fixed, the coil (or antenna) is also printed on the electronic yarn to operate the LEDs and sensors for a long time. It is convenient to make it implemented with. Electromagnetic waves generated from an electromagnetic wave generating device arranged in the vicinity can supply energy to the LEDs and the sensors in a non-contact manner through a coil connected to the LEDs and the sensors by electromagnetic induction. This eliminates the need for batteries in carpets and curtains.

  In addition, by adding light emitting elements such as LEDs with built-in wireless circuits with IDs to conventional cloths such as light-emitting climbers, light-emitting wall hangings, light-emitting goodwill, and light-emitting advertising cloths, the display function can be added, thereby adding more impact. Can be created. In this case, an external power source is not necessary by using the electronic yarn on which the solar cell is printed.

  Recently, a tag having a wireless integrated circuit (IC) has attracted attention. By using the electronic fiber or the electronic yarn of the present invention, an electronic fiber tag or an electronic yarn tag having a wireless IC, an FRID IC, a memory, or the like can be obtained. As a result, the electronic fiber tag or the electronic thread can be wound around or sewn on the object, instead of being attached to the object as in the prior art. The conventional tag was often damaged by appearance or peeled off, but the electronic fiber tag or electronic yarn of the present invention makes it difficult to recognize the presence of the tag from the outside, and it is difficult to wrap around or stick it to clothes. It can be attached more easily by sewing or wrapping around flexible rubber or leather.

  By incorporating a biological sensor such as a temperature sensor or a heart rate sensor and an electronic thread having a wireless circuit into an underwear or underwear that is usually worn, the underwear or underwear can have a security function. FIG. 8 shows a conceptual diagram of security wear in which electronic yarns with various biological sensors are incorporated. Although an electronic device such as a biosensor is smaller than the thread diameter and cannot be identified with the naked eye, only the electronic device is enlarged in FIG. 8 for easy understanding.

  In FIG. 8, the security wear 70 is based on a conventionally used fiber material, and includes various body sensors such as a body temperature sensor 71, a heart rate sensor 72, a pulse sensor 73, a blood pressure sensor 74, a sound sensor 75, and a position sensor 76. A plurality of electronic yarns mounted by a printing method or the like are incorporated into underwear or underwear, or partially replaced with a general fiber material. Furthermore, an electronic device such as a wireless device 77 for transmitting these sensor information wirelessly and a battery 78 are also mounted on the electronic thread. As a result, it is fused and integrated with the conventional fiber material, and when worn, the electronic device such as a sensor is not visible from the outside, and the body does not feel uncomfortable.

  Wearers of security wear with such advanced IT functions can ask for help from outside, such as family and police, at any time in the event of an emergency such as high fever or heart rate abnormalities. You can live a daily life.

  The electronic fiber, the electronic yarn, the electronic cloth, and the electronic garment of the present invention can transmit and receive various information while being worn as clothes, for example, by various electronic devices and electronic circuits incorporated therein. . Therefore, as clothing that incorporates information transmission media such as publishing cloth, bib, and streamers incorporating LEDs, biological sensors such as body temperature sensors, pulse sensors, blood pressure sensors, image sensors such as CCD and CMOS, position sensors, etc. It can be used for security wear that constantly transmits various information about a person.
