Electronic device comprising sensor module

1 . A wearable electronic device configured to be wearable around a user's wrist, the wearable electronic device comprising:

a housing comprising a front surface, a rear surface opposite to the front surface, and a side surface surrounding at least a part between the front surface and the rear surface and formed by a side bezel structure, wherein the side bezel structure comprises a recess structure;

a battery disposed in the housing;

a main printed circuit board disposed in the housing; and

a sensor module at least partially disposed in the recess structure,

wherein the sensor module comprises:

a board;

a biometric recognition sensor disposed on the board, wherein the biometric recognition sensor is configured to detect fingerprint information;

a sealing member on at least a part of the board encapsulating the biometric recognition sensor together with the board;

a biosignal sensing electrode spaced apart from the biometric recognition sensor and configured to detect a bioelectrical signal, wherein the biosignal sensing electrode is electrically connected to the board and at least partially exposed outside of the housing; and

a flexible printed circuit board electrically connected to the board and configured to electrically connect the board to the main printed circuit board, and

wherein the biosignal sensing electrode covers and contacts with the sealing member.

2 . The wearable electronic device of claim 1 , wherein the sensor module further comprises a connector mounted on the flexible printed circuit board.

3 . The wearable electronic device of claim 1 , wherein the biosignal sensing electrode forms at least a part of a first surface of the sensor module, a third surface of the sensor module opposite to the first surface, and a second surface of the sensor module around at least a part between the first surface and the third surface.

4 . The wearable electronic device of claim 1 , wherein the sensor module further comprises a fingerprint sensing circuit.

5 . The wearable electronic device of claim 1 , wherein the sensor module further comprises a first area overlapping with the biometric recognition sensor and a second area in which the biosignal sensing electrode is disposed.

6 . The wearable electronic device of claim 1 , wherein the sensor module further comprises an ultrasonic transceiver configured to transmit or receive ultrasonic waves.

7 . The wearable electronic device of claim 6 , wherein the sensor module further comprises a shielding member disposed under the board, wherein the shielding member is configured to reduce propagation, into the wearable electronic device, of ultrasonic waves generated by the ultrasonic transceiver.
