Abstract

A body-wearable electronic device and a method thereof are provided. The body-wearable device includes including a main body enclosure including a biometric signal sensor; a coupling member extending from the main body enclosure and coupling the main body enclosure to a user'"'"'s body; and a high-polymer actuator disposed in the coupling member, wherein, as the high-polymer actuator is driven, the biometric signal sensor closely contacts the user'"'"'s body.

Claims

1. A body-wearable electronic device comprising:

a main body enclosure comprising a biometric signal sensor;

a coupling member extending from the main body enclosure and coupling the main body enclosure to a user'"'"'s body; and

a high-polymer actuator disposed in the coupling member,

wherein, as the high-polymer actuator is driven, the biometric signal sensor closely contacts the user'"'"'s body.

2. The body-wearable electronic device of claim 1, wherein the coupling member comprises:

a first band extending from the main body enclosure and having an engagement member installed in an end portion thereof; and

a second band extending from the main body enclosure and having engagement holes formed corresponding to the engagement member,

wherein the first band and the second band are engaged with each other to form a ring shape together with the main body enclosure.

3. The body-wearable electronic device of claim 2, wherein the high-polymer actuator is disposed on the first band in a longitudinal direction of the first band.

4. The body-wearable electronic device of claim 3, wherein an end of the high-polymer actuator is fixed to a circuit board received in the main body enclosure and another end of the high-polymer actuator is fixed adjacent to the end portion of the first band, and the high-polymer actuator contracts the first band in the longitudinal direction when an electrical signal is applied to the high-polymer actuator.

5. The body-wearable electronic device of claim 4, wherein the first band comprises a bellows structure formed in at least a portion of the first band, and when the electric signal is applied to the high-polymer actuator, the high-polymer actuator contracts the portion of the first band where the bellows structure is formed.

6. The body-wearable electronic device of claim 5, wherein the portion of the first band where the bellows structure is formed is received in the main body enclosure.

7. The body-wearable electronic device of claim 4, further comprising a fixing member that passes through the first band in a position adjacent to the end portion of the first band and is coupled with the high-polymer actuator.

8. The body-wearable electronic device of claim 3, wherein the high-polymer actuator reduces a radius of curvature of the first band when an electrical signal is applied to the high-polymer actuator.

9. The body-wearable electronic device of claim 3, wherein the coupling member further comprises a plurality of band members that are arranged in a direction and are coupled displaceably with respect to each other to form the first band.

10. The body-wearable electronic device of claim 9, wherein the plurality of band members are coupled to at least one of:

move with respect to each other in an arranged direction, and

pivot with respect to each other.

11. The body-wearable electronic device of claim 9, wherein the coupling member further comprises:

receiving grooves formed in one respective surface of each of the plurality of band members,

wherein the receiving grooves are arranged continuously in adjacent to each other to receive the high-polymer actuator.

12. The body-wearable electronic device of claim 1, wherein the biometric signal sensor comprises at least one of a PhotoPlethysmoGraphy (PPG) sensor comprising a light source and a light-receiving sensor, a Galvanic Skin Reflex (GSR) sensor for detecting a sleep period, and a temperature sensor for measuring a change in a skin temperature.

13. The body-wearable electronic device of claim 1, further comprising a pressure sensor stacked on the biometric signal sensor,

wherein the pressure sensor detects whether the biometric signal sensor closely contacts the user'"'"'s body.

14. A method of detecting a biometric signal by a body-wearable device coupled to a user, the method comprising:

detecting, by a pressure sensor, a level of pressure applied by the body-wearable device to the user;

providing an electrical signal to a high-polymer actuator included a coupling member that couples the body-wearable device to the user such that the high-polymer actuator expands or contracts the coupling member; and

sensing, by the biometric signal sensor, when the high-polymer actuator expands or contracts the coupling member to a predetermined level of pressure, a biometric characteristic of the user.

15. The method of claim 14, wherein the coupling member includes a first band extending from the main body enclosure and having an engagement member installed in an end portion thereof, and further includes a second band extending from the main body enclosure and having engagement holes formed corresponding to the engagement member, and

wherein the first band and the second band are engaged with each other to form a ring shape together with the main body enclosure.

16. The method of claim 15, wherein the high-polymer actuator is disposed on the first band in a longitudinal direction of the first band.

17. The method of claim 16, wherein the first band includes a bellows structure formed in at least a portion of the coupling member, and wherein the high-polymer actuator expands or contracts the portion of the first band where the bellows structure is formed.

18. The method of claim 16, wherein the high-polymer actuator reduces a radius of curvature of the first band when an electrical signal is applied to the high-polymer actuator.

19. The method of claim 14, wherein the coupling member further includes a plurality of band members that are arranged in a direction and are coupled displaceably with respect to each other to form the first band, and

wherein the plurality of band members are coupled to at least one of:

move with respect to each other in an arranged direction, and

pivot with respect to each other.

20. The method of claim 14, wherein the biometric signal sensor includes at least one of a PhotoPlethysmoGraphy (PPG) sensor comprising a light source and a light-receiving sensor, a Galvanic Skin Reflex (GSR) sensor for detecting a sleep period, and a temperature sensor for measuring a change in a skin temperature.
