Wearable device

1. A wearable device comprising:

a body member including a heartbeat sensor;

a first band member and a second band member including an accommodating portion respectively formed at a portion coupled to the body member;

a flexible battery having a predetermined length with a plate shape having a predetermined area;

a circuit board disposed inside the body member and disposed above the flexible battery;

a connecting member having one end coupled to the circuit board and other end disposed below the flexible battery and electrically connected to the heartbeat sensor, and wherein the connecting member includes a portion connected to the heartbeat sensor and protruded toward the flexible battery;

a power receiving antenna disposed at a surface of the connecting member to wirelessly receive power and supply power to the flexible battery, and wherein the power receiving antenna surrounds the portion connected to the heartbeat sensor; and

a shielding sheet disposed between the flexible battery and the power receiving antenna,

wherein the shielding sheet is adhered to the power receiving antenna, and the shielding sheet shields a magnetic field generated by a radio signal induced in the power receiving antenna,

wherein an intermediate portion of the flexible battery is accommodated in the body member and each remaining end of the flexible battery are respectively accommodated in the accommodating portion of the first band member and the second band member; and

wherein the flexible battery is embedded in the body member, the first band member and the second band member such that the flexible battery is simultaneously positioned inside the body member, the first band member and the second band member;

wherein the flexible battery includes:

an electrode assembly, and wherein the electrode assembly includes a positive electrode, a negative electrode and a separator disposed between the positive electrode and the negative electrode; and

a cover member having a plate shape area configured to seal the electrode assembly;

wherein the cover includes a upper cover member covering a upper surface of the negative electrode and a lower cover member covering a lower surface of the positive electrode;

wherein the cover member includes a first pattern for contraction and relaxation in a longitudinal direction when the flexible battery is bent;

wherein the electrode assembly includes a second pattern for contraction and relaxation in a longitudinal direction when the flexible battery is bent;

wherein each of the first pattern and the second pattern includes a plurality of crests and troughs alternately positioned in the longitudinal direction of the cover member and the electrode assembly, and each of the crests and troughs is formed in a direction parallel to a width direction of the cover member and the electrode assembly, and

wherein the crests of the first pattern are formed to correspond to the crests of the second pattern and the troughs of the first pattern are formed to correspond to the troughs of the second pattern; and

wherein the crest of the electrode assembly is arranged between the crest of the upper cover member and the crest of the lower cover member, and

wherein the trough of the electrode assembly is arranged between the trough of the upper cover member and the trough of the lower cover member;

wherein the first pattern and the second pattern have a same behavior.

2. The wearable device of claim 1 , wherein a seating portion that includes a portion of the heartbeat sensor is formed at a bottom surface of the body member.

3. The wearable device of claim 1 , wherein the power receiving antenna is disposed at the surface opposite a surface of the connecting member connected to the heartbeat sensor.

4. The wearable device of claim 1 , wherein the connecting member is a flexible printed circuit board.

5. The wearable device of claim 4 , wherein the connecting member is folded at least once such that a portion thereof is disposed between the flexible printed circuit board and the flexible battery.

6. The wearable device of claim 5 , wherein a length of the portion of the connecting member disposed between the flexible printed circuit board and the flexible battery is greater than twice a width of the circuit board.

7. The wearable device of claim 1 , wherein the power receiving antenna receives power in a magnetic resonance manner or a magnetic induction manner.

8. The wearable device of claim 1 , wherein the portion of the flexible battery in the accommodating portion of the first band member and the second band member is entirely or partially corrugated.

9. The wearable device of claim 1 , comprising a communication unit configured to transmit heartbeat information measured by the heartbeat sensor.
