1 is a diagram for explaining an example in which a sensor device according to an embodiment operates.

Referring to FIG. 1 , the sensor device 100 may be embedded in the clothing 1 . Here, the sensor device 100 may be implemented as a tag attached to the clothing 1, but is not limited thereto. For example, the sensor device 100 may be implemented to be inserted into the clothing 1 .

Meanwhile, the clothing 1 may be underwear, but is not limited thereto. For example, the clothing 1 may include various types of clothing that the user can wear, such as tops, bottoms, or socks, including underwear.

The sensor device 100 detects whether the user wears it, and notifies this to the external device 200 . Specifically, the sensor device 100 may detect whether the user puts on or takes off the clothes 1 . For example, the sensor device 100 may detect whether the user puts on or takes off the clothing 1 based on the size of the capacitance. Also, the sensor device 100 may detect whether the user takes off the clothing 1 and does not put on the clothing 1 again for a predetermined period of time.

In addition, the sensor device 100 generates a notification signal indicating information on the fact that the user is wearing or undressing and information that a predetermined time has elapsed after the user has undressed, and transmits the notification signal to the external device 200 of a third party. do.

An example in which the sensor device 100 transmits a notification signal will be described later with reference to FIG. 2 .

Here, the third-party external device 200 means a digital device that can communicate with other devices by wire or wirelessly, for example, a smart phone, a desktop PC, a notebook PC, a laptop PC, a tablet PC, A wearable device may be included.

When the sensor device 100 transmits a notification signal to the third party's external device 200 , the third party can check in real time whether the user wears the clothing 1 .

Meanwhile, the sensor device 100 may not necessarily be embedded in the clothing 1 . In other words, the sensor device 100 is manufactured as a detachable device and may be attached to an object other than the clothing 1 . For example, the sensor device 100 may be attached to the body of the user, other items of the user (eg, the user's smart phone, etc.) or the body of a pet. In this case, when the distance between the sensor device 1 and the external device is more than a predetermined distance, the sensor device 1 may transmit a notification signal to the external device.

Hereinafter, an example of communication between the sensor device 100 and a third-party external device 200 will be described in detail with reference to FIG. 2 .

2 is a diagram for describing communication between a sensor device and an external device according to an exemplary embodiment.

Referring to FIG. 2 , the sensor device 100 may wirelessly communicate with the first external device 300 . Here, the first external device 300 is a device of a user wearing the clothing 1 , and the second external device 200 is a device of a third party other than the user. For example, the first external device 300 and the second external device 200 may be a smart phone, a desktop PC, a notebook PC, a laptop PC, a tablet PC, a wearable device, or the like.

The first external device 300 may communicate with the second external device 200 through the server 400 .

3 is a configuration diagram illustrating an example of a sensor device according to an embodiment.

Referring to FIG. 3 , the sensor device 100 includes a contact pad 111 , a conductive fiber 112 , a conductive rubber band 113 , a processor 120 , a Bluetooth module 130 , and a battery 140 .

When the user wears the clothing 1 , the contact pad 111 comes into contact with the user's body. For example, the contact pad 111 generates a signal according to the magnitude of the capacitance that is changed as the user's body comes into contact. Then, the contact pad 111 transmits the generated signal to the processor 120 . An example in which the contact pad 111 operates will be described later with reference to FIGS. 4A and 4B .

In particular, as the sensor device 100 according to the present invention is inserted into the clothing 1 , the sensor device 100 may be implemented as a tag attached to the clothing 1 . In this case, since the tag is made of a material different from that of a general tag, the tag may serve as the contact pad 111 for sensing a user's touch. For example, the contact pad 111 may include a substrate made of glass or polycarbonate.

In addition, the material of the tag may include nickel (Ni) or silver (Ag). Alternatively, the characters included in the tag may be printed with ink containing aluminum hydride (AlH3). Examples of tags manufactured to serve as the pad 120 will be described later with reference to FIGS. 5A and 5B .

The conductive fibers 112 refer to fibers constituting at least a portion of the clothing 1 . In other words, at least a portion of the garment 1 may be made of the electrically conductive fiber 112 . When the clothing 1 made of the electrically conductive fiber 112 is used, it is possible to check whether it is in contact with the user's body, so that the user's wearing or undressing can be sensed.

For example, the conductive fiber 112 may be manufactured by mixing a conductive material such as carbon or metal in the fiber. For example, the conductive fiber 112 may include a metal material such as nickel (Ni), gold (Au), or silver (Ag) or a carbon material such as carbon or graphite.

The conductive rubber band 113 means that as the user puts on the clothing 1 , the user's body comes into contact with the clothing 1 , and it can be sensed that a portion of the clothing 1 is stretched. For example, when the user does not wear the clothing 1, the conductive rubber band 113 has a constant resistance value (eg, about 350 Ω per inch) in an unstretched state, but when the user wears the clothing 1 When the conductive rubber band 113 is stretched according to the wear, the resistance value increases. Accordingly, when the conductive rubber band 113 is used, it is possible to check whether the user is wearing the clothing 1 .

For example, the conductive rubber band 113 may constitute a bend portion of the clothing 1, but is not limited thereto. In addition, the conductive rubber band 113 may be made of a carbon material, but is not limited thereto.

The above-described contact pad 111 , conductive fiber 112 , and conductive rubber band 113 may operate as one sensor module, and each may constitute a separate sensor module. In this specification, a separate configuration (eg, electrode, etc.) necessary for the contact pad 111 , the conductive fiber 112 , and the conductive rubber band 113 to detect whether the user's body is in contact is not described, but this is usually It can be easily derived by those skilled in the art.

The processor 120 controls the overall operation of the sensor device 100 .

In particular, the processor 120 detects whether the user's body is in contact with the sensor device 100 using signals transmitted from the contact pad 111 , the conductive fiber 112 , and the conductive rubber band 113 .

Specifically, when the sensor device 100 is inserted into the clothing 1 , as the user wears the clothing 1 , the user's body comes into contact with the contact pad 111 , the conductive fiber 112 , and the conductive rubber band 113 . do. Accordingly, it is possible to detect a change in the size of the capacitance according to the body contact of the processor 120 . Accordingly, the processor 120 may detect whether the user puts on or takes off the clothes 1 .

The processor 120 may be implemented as an array of a plurality of logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory in which a program executable in the microprocessor is stored. In addition, those skilled in the art can understand that the processor 120 may be implemented in other types of hardware.

The Bluetooth module 130 communicates with the first external device 300 . For example, the processor 120 determines whether the user puts on or takes off the clothing 1 by the operation of the contact pad 111 , the conductive fiber 112 , and the conductive rubber band 113 , or whether a predetermined time has elapsed after taking off the clothes 1 . generates a notification signal according to , and the Bluetooth module 130 transmits the notification signal to the first external device 300 .

The battery 140 supplies power required for the sensor device 100 to operate. Specifically, the battery 110 supplies power required to operate the contact pad 111 , the conductive fiber 112 , the conductive rubber band 113 , the Bluetooth module 130 , and the processor 120 . For example, the battery 140 may be a lithium ion battery, but is not limited thereto. For example, the battery 140 may be implemented as a lithium iron phosphate (LiFePO4) battery, a lithium cobalt oxide (LiCoO2) battery, a lithium titanate battery, or the like.

4A and 4B are diagrams for explaining an example in which a contact pad senses a user's body.

4A and 4B show the contact pad 111 and the electrodes 310 and 320 included in the sensor device 100 . Specifically, FIG. 4A illustrates an example in which the user's body does not come into contact with the contact pad 111 , and FIG. 4B illustrates an example in which the user's body comes into contact with the contact pad 111 .

The processor 120 based on the amount of change in capacitance in the first condition in which the object (eg, the user's body) does not contact the contact pad 111 and in the second condition in which the object is in contact with the contact pad 111 . Thus, it is possible to detect whether the object is in contact.

Referring to FIG. 4A , when the object is not in contact with the contact pad 111 , the processor 120 checks the amount of charge generated when the current output from the first electrode 310 is received by the second electrode 320 . do. As described above, a case in which the object does not contact the contact pad 111 is referred to as a first condition.

Meanwhile, referring to FIG. 4B , when the object comes into contact with the contact pad 111 , some of the current output from the first electrode 310 flows to the object. Accordingly, the current received by the second electrode 320 of FIG. 4B is different from the current received by the second electrode 320 of FIG. 3A . The processor 120 checks the amount of charge generated when the current output from the first electrode 310 is received by the second electrode 320 . As described above, the case in which the object contacts the contact pad 111 is referred to as a second condition.

The processor 120 may detect whether the object is in contact with the contact pad 111 according to a difference between the amount of charge under the first condition and the amount of charge under the second condition.

As an example, the processor 120 may detect whether the object is in contact through a method of comparing peaks. Specifically, the processor 120 may detect whether the object is in contact through the principle that the peak decreases when the amount of charge in the second condition is increased compared to the amount of charge in the first condition.

As another example, the processor 120 may detect whether the object is in contact through a frequency conversion method. Specifically, the processor 120 may detect whether the object is in contact through the principle that the frequency is lowered when the amount of charge in the second condition is increased compared to the amount of charge in the first condition.

5A and 5B are diagrams for explaining an example in which a sensor device is inserted into clothes.

5A and 5B illustrate examples in which the sensor device 100 is implemented as a tag attached to clothing.

As described above with reference to FIG. 3 , the sensor device 100 may be inserted into clothing (particularly, underwear). More preferably, the sensor device 100 may be implemented as a tag attached to clothing. In this case, the tag may be made of a material different from that of a tag attached to general clothing.

Referring to FIG. 5A , the sensor device 100 may be implemented as a tag 510 . Specifically, the tag 510 may be manufactured including nickel (Ni) or silver (Ag). Tags for general clothing are manufactured by weaving fibers of a non-conductive material. However, in the present invention, by adding nickel (Ni) or silver (Ag) as a material of the tag 510 , the tag 510 may perform the function of the sensor device 100 . Accordingly, the tag 510 may detect body contact as the user puts on clothes.

Referring to FIG. 5B , characters and other figures 521 included in the tag 520 may be printed with ink containing aluminum hydride (AlH3). Characters and other figures printed on tags of general clothing are printed with non-conductive ink. However, in the present invention, the tag 520 may perform the function of the sensor device 100 by printing characters and other figures 521 with ink containing aluminum hydride (AlH3). Accordingly, the tag 520 may detect body contact as the user puts on clothes.

Also, the examples described above with reference to FIGS. 5A and 5B may be combined. In other words, nickel (Ni) or silver (Ag) is added as a material of the tag, and characters and other figures included in the tag may be printed with ink containing aluminum hydride (AlH3).

According to the above description, the ultra-light sensor device 100 can be implemented as a tag for clothes, so that even when a user wears clothes, a feeling of foreignness or foreign body is not felt.

6 shows an example in which the band portion of the garment 1 is implemented as a conductive rubber band 113 .

When the user does not wear the clothing 1 , the conductive rubber band 113 has a constant resistance value in a non-stretched state. On the other hand, when the conductive rubber band 113 is stretched as the user wears the clothing 1, the resistance value increases. Accordingly, when the conductive rubber band 113 is used, it is possible to check whether the user is wearing the clothing 1 .

In operation 730 , the sensor device 100 determines whether a preset condition is satisfied after the user takes off the clothing 1 . For example, the sensor device 100 may determine whether a predetermined time has elapsed after the user takes off the clothing 1 .

For example, if the user does not put on the clothing 1 again after a predetermined time elapses after the user takes off the clothing 1 , the processor 120 determines that the user takes off the clothing 1 in order to solve the physiological phenomenon. It can be concluded that no

8 and 9 are flowcharts illustrating an example in which a notification signal is output from a second external device according to an operation of a sensor device according to an exemplary embodiment.

The flowcharts shown in FIGS. 8 and 9 are examples in which the sensor device 100 , the first external device 300 , the server 400 , and the second external device 200 described above with reference to FIGS. 1 to 7 operate it is about Accordingly, even if omitted below, the sensor device 100 , the first external device 300 , the server 400 , and the second external device 200 described above with reference to FIGS. 1 to 7 are illustrated in FIG. It can also be applied to the flowcharts of 8 and 9 .

Referring to FIG. 8 , in step 810 , the sensor device 100 and the first external device 300 are interconnected. Specifically, by pairing the Bluetooth module 130 included in the sensor device 100 and the Bluetooth module included in the first external device 300 , the sensor device 100 and the first external device 300 may be interconnected. there is.

In operation 820 , the sensor device 100 detects a human body contact. For example, when the sensor device 100 is inserted into clothing (particularly, underwear), the sensor device 100 may detect that the user's body is in contact by the user putting on the clothing. Here, the contact of the user's body may be sensed based on a change in capacitance.

In operation 830, the sensor device 100 generates a notification signal. Specifically, the processor 120 of the sensor device 100 may generate a notification signal after determining whether the above-described preset condition is satisfied with reference to FIG. 7 .

In steps 840 to 860 , the notification signal is transmitted in the order of the sensor device 100 → the first external device 300 → the server 400 → the second external device 200 . Here, the first external device 300 is a device of a user wearing clothes into which the sensor device 100 is inserted, and the second external device 200 is a device of a third party. Meanwhile, a process in which the notification signal is transmitted between devices is the same as that of a typical wireless communication process, and thus a detailed description thereof will be omitted.

In step 870 , the second external device 200 outputs a notification signal. For example, the second external device 200 may output a sound through a speaker, a vibration through a vibration motor, or an image through a display.

Comparing FIGS. 9 and 8 , the server 400 is omitted in the flowchart of FIG. 9 . In other words, the first external device 300 may be connected to the second external device 200 without the involvement of the server 400 . Accordingly, the notification signal may be directly transmitted from the first external device 300 to the second external device 200 .

In step 910 , the sensor device 100 and the first external device 300 are interconnected. Specifically, by pairing the Bluetooth module 130 included in the sensor device 100 and the Bluetooth module included in the first external device 300 , the sensor device 100 and the first external device 300 may be interconnected. there is.

In operation 920, the sensor device 100 detects a human body contact. For example, when the sensor device 100 is inserted into clothing (particularly, underwear), the sensor device 100 may detect that the user's body is in contact by the user putting on the clothing. Here, the contact of the user's body may be sensed based on a change in capacitance.

In operation 930 , the sensor device 100 generates a notification signal. Specifically, the processor 120 of the sensor device 100 may generate a notification signal after determining whether the above-described preset condition is satisfied with reference to FIG. 7 .

In steps 940 and 950 , the notification signal is transmitted in the order of the sensor device 100 → the first external device 300 → the second external device 200 . Here, the first external device 300 is a device of a user wearing clothes into which the sensor device 100 is inserted, and the second external device 200 is a device of a third party. Meanwhile, a process in which the notification signal is transmitted between devices is the same as that of a typical wireless communication process, and thus a detailed description thereof will be omitted.

Meanwhile, in addition to the above with reference to FIGS. 3 to 9 , the sensor device 100 may further include an additional sensor. As an additional sensor is further included in the sensor device 100 , a health risk of a user wearing the clothing 1 including the sensor device 100 may be detected. Also, when it is determined that an abnormality has occurred in the user's health, the sensor device 100 may notify a third party thereof. Therefore, when the user is in an emergency situation, a third party can quickly take measures to rescue the user.

Hereinafter, an example in which an additional sensor is included in the sensor device 100 will be described with reference to FIGS. 10 and 11 .

10 is a configuration diagram illustrating another example of a sensor device according to an embodiment.

Referring to FIG. 10 , the sensor device 101 includes a contact pad 111 , a conductive fiber 112 , a conductive rubber band 113 , a processor 120 , a Bluetooth module 130 , a battery 140 , and an additional sensor 150 . ) is included. The contact pad 111 , the conductive fiber 112 , the conductive rubber band 113 , the processor 120 , the Bluetooth module 130 and the battery 140 shown in FIG. 10 are the same as described above with reference to FIG. 3 . Accordingly, detailed descriptions thereof will be omitted.

The additional sensor 150 may monitor the health state of the user wearing the clothing 1 . Specifically, based on the value sensed by the additional sensor 150 , the processor 120 may check the user's health state.

As an example, when the processor 120 determines that the user's health is abnormal, the processor 120 may transmit an alarm to the first external device 300 and/or the second external device 200 . Therefore, the third party can confirm that there is an abnormality in the user's health, and can take relief measures accordingly. In this case, the processor 120 transmits information on the user's current location together, so that the relief action for the user can be efficiently carried out.

As another example, when the processor 120 determines that an abnormality has occurred in the user's health, the processor 120 may make an emergency contact to an emergency contact (eg, contact information such as a hospital or an ambulance). Specifically, the processor 120 may transmit an alarm to the first external device 300 through the Bluetooth module 130 , and the first external device 300 may make an emergency contact with the emergency contact. In this case, the processor 120 transmits information on the user's current location together, so that the relief action for the user can be efficiently carried out.

As an example, the additional sensor 150 may include an acceleration sensor and/or a gyro sensor. The acceleration sensor is a concept using the dynamic motion of a rotating object, and refers to a sensor that can measure the position and set the direction of an object. Meanwhile, the gyro sensor measures angular velocity, unlike an acceleration sensor that measures acceleration. A gyroscope is a device that measures angular velocity, and a chip-type gyro sensor to which MEMS technology is applied also measures angular velocity. Angular velocity refers to the angle of rotation per hour. The measurement principle of the gyro sensor is as follows.

For example, in a horizontal state (stationary state), the angular velocity is also 0 degrees/sec. If an object is tilted by 50 degrees while moving for 10 seconds, the average angular velocity over 10 seconds is 5 degrees/sec. If the inclination angle of 50 degrees is maintained in the stationary state, the angular velocity becomes 0 degrees/sec. Through this process, the angular velocity changed from 0 → 5 → 0, and the angle increased from 0 degrees to 50 degrees.

To find the angle from the angular velocity, you need to integrate it over the whole time. Since the gyro sensor measures the angular velocity in this way, the tilt angle can be calculated by integrating the angular velocity over the entire time. However, in the gyro sensor, an error occurs due to the influence of temperature, and the error is accumulated during the integration process so that the final value drifts. Therefore, the gyro sensor must compensate the error by using the temperature sensor as well.

From the point of view of a long time in a stationary state, the tilt angle calculated by the accelerometer shows a correct value, but the gyro sensor shows an incorrect value as time goes by. Conversely, the gyro sensor may show a correct value in terms of a short moving time, but the accelerometer sensor may have a different calculated value than the tilted angle. Therefore, the roll or pitch value is calculated by applying an algorithm that can compensate for each disadvantage using both the acceleration sensor and the gyro sensor. A Kalman filter is a widely applied compensation method and filtering.

When the additional sensor 150 is an acceleration sensor and/or a gyro sensor, a sudden collapse of the user may be detected through the additional sensor 150 . Specifically, through the value sensed by the additional sensor 150 , the processor 150 may determine whether the user's posture is suddenly changed. If the user's posture is abruptly changed, and more specifically, if a value corresponding to the user's body falling is sensed, the processor 150 performs the first external device 300 , the second external device 200 and/or Alternatively, an alarm or emergency call can be sent to an emergency contact.

As another example, the additional sensor 150 may include an electrocardiogram (ECG) sensor and/or a pulse wave (PPG) sensor. When the additional sensor 150 is an electrocardiogram sensor and/or a pulse wave sensor, it is possible to detect whether the user has a cardiovascular disease through the additional sensor 150 . Specifically, through the value sensed by the additional sensor 150 , the processor 150 may determine whether the user's ECG or pulse wave is out of a normal range. If a value of the user's ECG or pulse wave is sensed outside the normal range, the processor 150 transmits an alarm or emergency contact to the first external device 300 , the second external device 200 , and/or the emergency contact. can do.

As another example, the additional sensor 150 may include a sensor that detects the user's health condition through the user's skin. Specifically, the additional sensor 150 may be a sensor that monitors the dryness of the user's skin, the color of the skin, the temperature of the skin, and the like. When it is determined that there is an abnormality in the user's health through the value collected from the additional sensor 150 , the processor 150 sends an alarm to the first external device 300 , the second external device 200 and/or the emergency contact. Emergency communications can be sent.

The additional sensor 150 includes a first sensor group consisting of an acceleration sensor and/or a gyro sensor, a second sensor group consisting of an electrocardiogram sensor and/or a pulse wave sensor, and a sensor that detects the user's health condition through the user's skin. It may be any one of the three sensor groups, and two or more of the first sensor group to the third sensor group may be combined.

11 is a flowchart illustrating another example in which a sensor device according to an embodiment operates.

The flowchart shown in FIG. 11 is for an example in which the sensor device 101 described above with reference to FIG. 10 operates. Accordingly, even if omitted below, the contents of the sensor device 101 described above with reference to FIG. 10 may also be applied to the flowchart of FIG. 11 .

In operation 1110 , the sensor device 101 acquires a sensor value of the additional sensor 150 . For example, the additional sensor 150 may include a first sensor group composed of an acceleration sensor and/or a gyro sensor, a second sensor group composed of an electrocardiogram sensor and/or a pulse wave sensor, and the user's skin through the user's skin. It may be any one of the third sensor groups composed of sensors, or a combination of two or more of the first sensor group to the third sensor group.

In operation 1120 , the sensor device 101 determines whether a sensor value of the additional sensor 150 satisfies a preset condition. Here, the satisfaction of the preset condition may mean that the sensor value obtained from the additional sensor 150 exceeds the range of the sensor value that can be obtained according to the user's normal life. In other words, satisfying the preset condition may mean that an abnormality has occurred in the user's health.

For example, the sensor device 101 continuously collects sensor values from the additional sensors 150 and stores the collected sensor values, so that when the user leads a normal life (ie, the user lives in a healthy state) You can set the range of the sensor value of ). Accordingly, the sensor device 101 may determine whether an abnormality has occurred in the user's health through the sensor value of the additional sensor 150 .

In operation 1130, the sensor device 100 generates a notification signal. Specifically, the processor 120 may generate a notification signal and transmit it to an external device (eg, the first external device 300 and the second external device 200 ) through the Bluetooth module 130 . Alternatively, the processor 120 may make an emergency contact to the emergency contact through the first external device 300 .

12 is a diagram for explaining an example in which the sensor device is attached to a target other than clothing according to an embodiment. Referring to FIG. 12 , the sensor device 100 is attached to a target other than clothing 1 . it might be For example, the sensor device 100 may be manufactured as a detachable device, and the sensor device 100 may be manufactured to be freely attached to an article other than the body or clothing 1 of a person or an animal. 12 illustrates an example in which the sensor device 100 is attached to a user's body, a pet's body, or a user's article (eg, a user's other smart phone). However, an object to which the sensor device 100 can be attached is not limited to the example illustrated in FIG. 12 .

In this case, when the object to which the sensor device 100 is attached falls more than a predetermined distance from the user's smart phone 300, an alarm signal may be generated. Accordingly, a situation in which the user loses the object to which the sensor device 100 is attached can be prevented.

For example, the user's smart phone 300 may communicate with another smart phone 200 through the server 400 . Here, the other smart phone 200 may be a smart phone owned by a third party other than the user. Also, if necessary, the user's smart phone 300 may directly communicate with another smart phone 200 . That is, the user's smart phone 300 may transmit the notification signal received from the sensor device 100 to the server 400 , and the server 400 may transmit the notification signal to the other smart phone 200 . Alternatively, the user's smart phone 300 may directly transmit a notification signal received from the sensor device 100 to another smart phone 200 .

Here, the notification signal may be a sound output through a speaker, a vibration output through a vibration motor, or an image output through a display.
