Abstract

An embodiment is a device including a substrate, the substrate being flexible. The device further comprises an electrode configured to be in contact with a living body, a circuit connected to the electrode via an electric wiring, a wireless transceiver connected to the circuit and configured to transmit and receive signals, a power supply configured to supply electric power to the circuit and the wireless transceiver, and a battery connected to the power supply, where the electrode, the circuit, the wireless transceiver, the power supply and the battery are mounted on the substrate, and the substrate is configured to be deformed to make the wireless transceiver arranged away from the living body when attached to the living body.

Claims (35)

1 . A wearable device comprising:

a substrate, the substrate being flexible;

an electrode configured to be in contact with a living body;

a circuit connected to the electrode via an electric wiring;

a wireless transceiver connected to the circuit and configured to transmit and receive signals;

a power supply configured to supply electric power to the circuit and the wireless transceiver; and

a battery connected to the power supply, wherein:

the electrode, the circuit, the wireless transceiver, the power supply and the battery are mounted on the substrate, and

the substrate is configured to be deformed such that a first portion of the substrate is in contact with the living body and a second portion of the substrate is spaced apart from the living body, the wireless transceiver being arranged on the second portion of the substrate.

2 . The wearable device of claim 1 , wherein the circuit, the wireless transceiver, the power supply, and the battery are arranged on one surface of the substrate, and wherein the electrode is arranged on another surface of the substrate.

3 . The wearable device of claim 1 , wherein the substrate includes a base, an extension, and a connection that connects the base and the extension, wherein the electrode, the circuit, the wireless transceiver, the power supply, and the battery are arranged on one surface of the substrate, wherein another surface of the base is configured to be in contact with the living body, wherein the electrode is included in an end portion of the extension, and wherein the substrate is configured to be deformed at the connection to bring the electrode into contact with the living body.

4 . The wearable device of claim 3 , wherein the circuit, the wireless transceiver, the power supply, and the battery are not arranged on the base.

5 . The wearable device of claim 4 , wherein the electric wiring is arranged in a portion of the substrate that is not configured to be in contact with the living body.

6 . The wearable device of claim 5 , wherein the wearable device includes an opening in the portion where the electric wiring is arranged in the substrate.

7 . The wearable device of claim 1 , further comprising:

a sensor, the sensor comprising an acceleration sensor, a bending detection sensor, or a magnetic proximity sensor.

8 . The wearable device of claim 7 , further comprising a magnetic switch.

9 . The wearable device of claim 1 , wherein the electrode is formed by the electric wiring.

10 . A device comprising:

a substrate;

an electrode configured to be in contact with a living body;

a circuit connected to the electrode via an electric wiring;

a wireless transceiver connected to the circuit and configured to transmit and receive signals;

a power supply configured to supply electric power to the circuit and the wireless transceiver; and

a battery connected to the power supply, the electrode, the circuit, the wireless transceiver, the power supply and the battery being mounted on the substrate, the substrate being configured to be deformed such that a first portion of the substrate is in contact with the living body and a second portion of the substrate is spaced apart from the living body, the wireless transceiver being arranged on the second portion of the substrate, the circuit, the wireless transceiver, the power supply, and the battery being arranged on one surface of the substrate, and the electrode being arranged on another surface of the substrate.

11 . The device of claim 10 , wherein the substrate includes a base, an extension, and a connection that connects the base and the extension, wherein the electrode is arranged at an end portion of the extension, and wherein the substrate is configured to be deformed at the connection to bring the electrode into contact with the living body.

12 . The device of claim 11 , wherein the circuit, the wireless transceiver, the power supply, and the battery are not arranged on the base.

13 . The device of claim 10 , wherein the electrode is formed by the electric wiring.

14 . The device of claim 11 , wherein the substrate is configured to be deformed such that the wireless transceiver is arranged away from the living body when attached to the living body.

15 . The wearable device of claim 3 , wherein the substrate is configured to be deformed such that the wireless transceiver is arranged away from the living body when attached to the living body.

16 . The wearable device of claim 1 , wherein, when the substrate is deformed, the circuit, the power supply, and the battery are positioned between opposing portions of the substrate.

17 . The wearable device of claim 16 , wherein component parts on respective opposing inner faces of the substrate do not spatially overlap each other when the substrate is deformed.

18 . The wearable device of claim 1 , wherein a distance between the wireless transceiver and the living body is between 1 mm and 10 mm when the first portion of the substrate is in contact with the living body.

19 . The device of claim 10 , wherein, when the substrate is deformed, the circuit, the power supply, and the battery are positioned between opposing portions of the substrate.

20 . The device of claim 19 , wherein component parts on respective opposing inner faces of the substrate do not spatially overlap each other when the substrate is deformed.
