A module that performs sensing among the plurality of modules 3 is also referred to as a sensor module. A module that performs actuation among the plurality of modules 3 is also referred to as an actuator module. The fabric 1 is, for example, a cloth.

In the present embodiment, the common electrode 2 includes a surface electrode 2A provided on the front surface side of the fabric 1 and a back electrode 2B provided on the back surface side of the fabric 1.
Here, the front electrode 2A and the back electrode 2B as the common electrode 2 may be provided, for example, in a lattice shape on the entire surface, or may be provided in a layer shape on the entire surface, but are provided on the front surface side. The front electrodes are all connected, and the back electrodes provided on the back side are all connected. The common electrode 2 functions as a power supply wiring for sending a power supply signal from the power supply module 4 to the plurality of modules 3. For this reason, the common electrode 2 is also referred to as a common power supply wiring.

The fabric 1 having such a common electrode 2 is, for example, a film-like conductive material represented by “COCOMI” (registered trademark) manufactured by Toyobo Co., Ltd., or conductive fibers represented by “AGposs” (registered trademark) manufactured by Mitsufuji. It can be easily formed by using a conductive cloth represented by “hitoe” (registered trademark) manufactured by Toray Industries, Inc.
In the cloth 1 having such a common electrode 2, since the common electrode 2 is provided over the entire surface of the cloth 1, the plurality of modules 3 and the power supply module 4 can be installed anywhere on the cloth 1. is there. For this reason, the plurality of modules 3 and the power supply module 4 can be respectively arranged at optimum locations without being affected by the difference in the body shape of the user.

  For example, the sensor modules included in the plurality of modules 3 can be arranged at an optimum location according to necessary information (data to be acquired). In addition, the actuator modules included in the plurality of modules 3 can be arranged at an optimum place for actuation. This makes it possible to acquire and actuate sensing data with high accuracy. Moreover, the power supply module 4 can be arrange | positioned in the optimal places, such as a place near a waist | hip | lumbar, for example.

The plurality of modules 3 and the power supply module 4 are attached so as to be connected to the electrodes 2A and 2B on the cloth 1 in which two kinds of electrodes 2A and 2B are formed on the front and back as described above.

A plurality of modules 3 and a power supply module 4 are attached to the fabric 1 so as to be connected to the two types of electrodes 2A and 2B on the front and back sides by fixing with a surface extraction electrode 6 as a fastener from the opposite side across 1 You can do that.

It should be noted that an insulating layer 7 is provided around the portion of the pin-shaped back surface extraction electrode 5 that pierces the cloth 1 so that the pin-shaped back surface extraction electrode 5 is not electrically connected to the front surface electrode 2A or the front surface extraction electrode 6. preferable.
As described above, the plurality of modules 3 and the power supply module 4 can be easily attached to the fabric 1.

For this reason, it is possible to arbitrarily attach only the sensor module or actuator module required by the user. In addition, the user can attach to an optimal place (or a favorite place) according to his / her body shape.
Therefore, the degree of freedom of the installation positions of the plurality of modules 3 and the power supply modules 4 is high, and it is possible to cope with a difference in the body shape of the user, and highly accurate sensing data can be acquired and actuated.

In the present embodiment, as shown in FIG. 2, the sensor module 3A included in the plurality of modules 3 includes a sensor 8, a control unit 9, and a communication module 10 (communication unit; for example, BLE, Wi-Fi, ZigBee And a filter (frequency filter) 11. The communication module 10 can communicate with the external terminal 18.
Here, the sensor 8 is, for example, a heart rate sensor, a sweat sensor, an acceleration sensor, a temperature / humidity sensor, a bending sensor, or the like. These sensors are attached to a place as shown in FIG. 4, for example.

The actuator module 3B included in the plurality of modules 3 includes an actuator 12, a control unit 13, and a filter (frequency filter) 14 (see, for example, FIG. 6).
Here, the actuator 12 is, for example, a vibrator, an indicator [for example, an LED (light emitting diode) or the like], etc., and by using these, navigation is performed or a pace distribution at the time of running is instructed. It becomes possible. These actuators 12 are attached to a place as shown in FIG. 4, for example.

In the present embodiment, as shown in FIG. 2, the power supply module 4 includes a battery (or generator) 15, a control unit 16, and an oscillation circuit 17.
Here, the power supply module 4 may be mounted only with a battery, may be mounted only with a generator (power generation device), or may be mounted with both a battery and a generator. It doesn't matter what kind or quantity it does. For example, only one power supply module 4 or a plurality of power supply modules 4 may be provided.

  Further, for example, the power supply module 4 is provided with a vibration power generation device, and can be attached to, for example, a foot to increase power generation efficiency (see, for example, FIG. 4). Further, for example, the power supply module 4 is provided with a solar power generation device, and can be attached to, for example, the head to increase the power generation efficiency (see, for example, FIG. 4). Further, for example, the power supply module 4 is provided with a power generation device using a temperature difference, and can be attached to, for example, a shoulder or the like to increase power generation efficiency (see, for example, FIG. 4).

  Here, the plurality of modules 3 are described by taking as an example a case where one sensor or one actuator is mounted, but the present invention is not limited to this. For example, a plurality of sensors 3 Alternatively, a plurality of actuators may be mounted, and, for example, a sensor and an actuator may be mounted together. Further, by mounting a capacitor or a small secondary power source between the filter and the control unit in the plurality of modules 3, more stable sensing and actuation can be performed.

  The front electrode 2A and the back electrode 2B as the common electrode 2 are connected to the oscillation circuit 17 provided in the power supply module 4 and the filter 11 (14) provided in each module 3 (3A, 3B). Under the control of the control unit 16 provided in the power supply module 4, a power supply signal (with an arbitrary frequency or waveform) is sent from the power supply module 4 to each module 3 (3A, 3B) via the front electrode 2A and the back electrode 2B as the common electrode 2. Power signal) is sent. In each module 3 (3A, 3B), the received power signal is transmitted to the control unit 9 (13) via the frequency filter 11 (14), so that power is supplied to the control unit 9 (13). It has become so.

Here, in order to send a power signal from the power supply module 4 to each module 3 (3A, 3B) via the surface electrode 2A and the back electrode 2B as the common electrode 2, the surface electrode 2A as the common electrode 2 is set to + V (or −V), and the back electrode 2B is set to the ground (GND). Note that the present invention is not limited to this, and for example, a differential may be used instead of the GND standard.
In this case, the power supply module 4 may send the same power supply signal to the plurality of modules 3 (3A, 3B). For example, the power supply module 4 may send power supply signals having the same frequency or waveform to the plurality of modules 3 (3A, 3B). Further, for example, a power signal may be sent to all of the plurality of modules 3 (3A, 3B) at a certain time interval or when it is desired to perform sensing or actuation. The plurality of modules 3 (3A, 3B) may be provided with a frequency filter 11 (14) that allows power supply signals having the same frequency to pass therethrough.

  Here, the plurality of modules 3 (3A, 3B) are each provided with the filter 11 (14), and the power supply module 4 is provided with the oscillation circuit 17. However, the present invention is not limited to this. For example, the plurality of modules 3 (3A, 3B) may be configured not to include the filter 11 (14), and the power supply module 4 may be configured not to include the oscillation circuit 17. Further, in the case where the plurality of modules 3 (3A, 3B) are not provided with the filter 11 (14), the control unit 9 (13) may be configured to be able to identify power supply signals having the same waveform.

The configuration is not limited to the configuration of the above-described embodiment. For example, the plurality of modules 3 (3A, 3B) each include a frequency filter 11 (14) that allows power supply signals having different frequencies to pass therethrough. Sensing or actuation may be performed according to the power supply signal that has passed (14).
That is, the plurality of modules 3 (3A, 3B) are each provided with an arbitrary frequency filter 11 (14) specific to each module 3 (3A, 3B), and the received power supply signal passes through the frequency filter 11 (14). When the received power signal passes through the frequency filter 11 (14), power is supplied to the control unit 9 (13), and the control unit 9 (13) supplies the sensor 8 or actuator. 12 may be controlled to perform sensing or actuation. In this case, the power supply module 4 may send any one of power signals having different frequencies that pass through the frequency filter 11 (14) to the plurality of modules 3 (3A, 3B).

  For example, as shown in FIG. 5, one sensor module 3A (reception module 1 in FIG. 5) on which a filter 11 (filter f1 in FIG. 5) that passes a power signal of frequency f1 is mounted, and a power source of frequency f2. A power signal of the frequency f1 from the power module 4 (in FIG. 5, the power source) is sent to both of the other sensor modules 3A (receiving module 2 in FIG. 5) equipped with the filter 11 (filter f2 in FIG. 5) that passes the signal. Signal 1) is transmitted simultaneously.

  In this case, power is supplied to the control unit 9 of one sensor module 3A (reception module 1 in FIG. 5), and sensing data is acquired by the sensor 8 (sensor 1 in FIG. 5). On the other hand, since no power is supplied to the control unit 9 of the other sensor module 3A (reception module 2 in FIG. 5), sensing data is not performed by the sensor 8 (sensor 2 in FIG. 5).

As described above, the filter 11 (filter f1, filter f2 in FIG. 5) peculiar to each sensor module 3A is mounted, and a power supply signal having a frequency corresponding to the filter characteristic is supplied from the power supply module 4, thereby providing a plurality of Even if the sensor module 3A is connected, it is possible to acquire target sensing data.
For example, as shown in FIG. 6, one actuator module 3 </ b> B equipped with a filter 14 (filter f <b> 1 in FIG. 6) that passes a power signal having a frequency f <b> 1 and a filter 14 that passes a power signal having a frequency f <b> 2 ( In FIG. 6, the power supply signal (frequency signal 1 in FIG. 6) is simultaneously transmitted from the power supply module 4 to both of the other actuator modules 3B equipped with the filter f2).

  In this case, electric power is supplied to the control unit 13 of one actuator module 3B (actuator module 1 in FIG. 6), and actuation is performed by the actuator 12 (actuator 1 in FIG. 6). On the other hand, since no power is supplied to the control unit 13 of the other actuation module 3B (actuator module 2 in FIG. 6), the actuator 12 (actuator 2 in FIG. 6) does not actuate.

In this way, a filter 14 (filter f1, filter f2 in FIG. 6) peculiar to each actuator module 3B is mounted, and a power supply signal having a frequency corresponding to the filter characteristics is supplied from the power supply module 4. Even if the actuator module 3B is connected, the target actuation can be performed.
For example, the power supply module 4 sends the modulated power supply signal to the plurality of modules 3 (3A, 3B), and each of the plurality of modules 3 (3A, 3B) demodulates the received power supply signal. Then, sensing or actuation may be performed according to the demodulated waveform of the power signal. As described above, a modulated wave may be used as the power supply signal.

In this case, it is assumed that the plurality of modules 3 (3A, 3B) do not include the filter 11 (14), the control unit 9 (13) demodulates the power signal, identifies the waveform of the demodulated power signal, and the module. Sensing or actuation may be performed when the waveform is peculiar to, and sensing or actuation should not be performed otherwise.
Further, for example, the power supply module 4 is configured to send a modulated power supply signal to the plurality of modules 3 (3A, 3B), and each of the plurality of modules 3 (3A, 3B) transmits power supply signals having different frequencies. A frequency filter 11 (14) to be passed may be provided, the power signal that has passed through the frequency filter 11 (14) may be demodulated, and sensing or actuation may be performed according to the frequency or waveform of the demodulated power signal. . As described above, a modulated wave may be used as the power supply signal.

For example, when an AM modulated wave is used as a power supply signal and filtering is performed using the frequency of the carrier wave and the frequency of the signal wave, the processing is performed in the plurality of modules 3 (3A, 3B) according to the procedure shown in FIG. You can do it.
Here, it is assumed that an AM modulated wave composed of a carrier wave of frequency f1 and a signal wave of frequency f2 is sent from the power supply module 4 to the plurality of modules 3 (3A, 3B) as a power supply signal.

The plurality of modules 3 (3A, 3B) include, as the frequency filter 11 (14), a first frequency filter (carrier frequency filter) that passes a power signal (carrier wave) having a frequency fa1 and a power signal (frequency filter for fa2). And a second frequency filter (signal wave frequency filter) that passes the signal wave).
First, the plurality of modules 3 (3A, 3B) receive an AM modulated wave composed of a carrier wave having a frequency f1 and a signal wave having a frequency f2 as a power supply signal, and the frequency f1 of the carrier wave of the power supply signal passes through the first frequency filter. If the frequency fa1 can pass, the process proceeds to the YES route in step S1, the power signal passes through the first frequency filter, the power signal is supplied to the control unit 9 (13), and the control unit 9 (13) It is activated (step S2).

On the other hand, if the frequency f1 of the carrier wave of the power supply signal is not the frequency fa1 that can pass through the first frequency filter, the process proceeds to the NO route in step S1, and the power supply signal does not pass through the first frequency filter. 13) does not start.
Next, when the control unit 9 (13) is activated in step S2, the control unit 9 (13) demodulates the received power signal (modulated wave) (step S3).

Next, when the frequency f2 of the demodulated power supply signal (signal wave) is the frequency fa2 that can pass through the second frequency filter, the process proceeds to the YES route in step S4, and the power supply signal passes through the second frequency filter and is controlled. The sensor 8 or the actuator 12 is controlled by the unit 9 (13), and sensing or actuation is performed (step S5).
And sensing data is transmitted to the external terminal 18 by the communication module 10 (step S6), and the control part (for example, microcomputer) 9 (13) is stopped (step S7).

On the other hand, when the frequency f2 of the demodulated signal wave is not the frequency fa2 that can pass through the second frequency filter, the process proceeds to the NO route in step S4, and the signal wave does not pass through the second frequency filter. (13) is stopped (step S7).
Thus, by performing a plurality of stages of determination processing, it becomes possible to distinguish and drive a larger number of sensor modules 3A and actuator (indicator) modules 3B than in the case of performing one-stage determination processing.

  In addition, although the case where the first and second frequency filters are used is described as an example here, the present invention is not limited to this. For example, only the first frequency filter is used and the second frequency filter is used. Thus, the control unit 9 (13) may perform sensing or actuation according to the demodulated waveform of the power signal. That is, the control unit 9 (13) identifies the waveform of the demodulated power supply signal, and performs sensing or actuation when the waveform is unique to the module, and does not perform sensing or actuation otherwise. May be.

In addition, for example, it is possible to acquire sensing data from a plurality of modules 3 (3A, 3B) by changing the power signal (frequency or waveform of the power signal) in time series. For example, sensing data can be acquired at different time intervals for each sensor.
By the way, in this embodiment, when each of the plurality of modules 3 (3A, 3B) receives a power signal sent from the power module 4 via the common electrode 2 and is supplied with power, the control unit 9 (13) controls the sensor 8 or the actuator 12 to perform sensing or actuation (for example, indication).

  Then, the plurality of modules 3 (3A, 3B) send the sensing data (sensor information) obtained by the sensor 8 to an external device such as a smartphone, a wearable terminal (eg, a wristwatch type), a data logger, etc. Data processing such as processing for storing data, processing for displaying data, or other processing is performed at the terminal (external terminal; management terminal) 18.

In this case, it is assumed that the electronic device 19 configured as described above (see, for example, FIG. 1, FIG. 2, FIG. 5 and FIG. 6) and the terminal 18 configured to be communicable with the electronic device 19 The system is configured, and the terminal 18 is provided with a data processing unit that receives and processes data obtained by the plurality of modules 3 (3A, 3B).
Alternatively, the sensing data may be processed in the module and the result may be transmitted to the external management terminal 18. For example, this corresponds to a case where the number of steps is converted based on acceleration information and transmitted.

For example, the power supply module 4 also includes a communication module, and sensing data obtained by the sensor 8 is sent to the power supply module 4 by the communication module, and the power supply module 4 stores the data. Processing or other processing may be performed.
In this case, the information system is configured to include the electronic device 19 configured as described above, and the plurality of modules 3 (3A, 3B) and the power supply module 4 are configured to be able to communicate with each other. The power supply module 4 is provided with a data processing unit that receives and processes the data obtained in 3B). Note that data may be sent from the power supply module 4 to the external terminal 18 and further processed by the terminal 18. In this case, the information system includes a terminal 18 configured to be able to communicate with the power supply module 4.

  A command or information (for example, information related to navigation) is sent from the terminal 18 to the power supply module 4, and based on this, the power supply signal as described above is sent from the power supply module 4 to the plurality of modules 3 (3A, 3B). May be. Further, the power signal as described above may be sent from the power module 4 to the actuator module 3B based on information (for example, pace distribution) obtained as a result of processing the sensing data by the terminal 18 or the power module 4. .

  Furthermore, for example, as shown in FIG. 2, data may be sent from the terminal 18 to the server 21 via the network 20 and the server 21 may perform data processing. In this case, the information system includes a server 21 that is connected to the terminal 18 via the network 20 and processes data transmitted from the electronic device 19. As a result, for example, it is possible to provide various services as cloud services, such as collecting and accumulating sensing data, building a database, analyzing these data, and feeding back the results. Become.

Therefore, the electronic apparatus and information system according to the present embodiment eliminates the influence of the difference in the body shape of the user, enables various sensors and actuators to be installed at optimal locations, and acquires highly accurate sensing data.
