1. A wearable electronic device comprising:
a display;
at least one processor operatively connected to the display;
a cover facing the display and comprising a light-transmitting material;
a flexible printed circuit board having a first surface facing the cover, and a second surface corresponding to an opposite surface of the first surface;
a wireless charging coil disposed to surround the flexible printed circuit board;
a first bio-signal sensing unit comprising a light receiver and a light emitter mounted on the first surface of the flexible printed circuit board;
a second bio-signal sensing unit comprising an internal electrode formed inside the cover, corresponding to a portion facing the flexible printed circuit board, and an external electrode electrically connected to the internal electrode and formed outside the cover;
a contact having one end contacting the first surface of the flexible printed circuit board, extending to the cover so that the opposite end thereof is connected to the internal electrode of the second bio-signal sensing unit; and
a signal processor mounted on the second surface of the flexible printed circuit board comprising circuitry configured to process a first bio-signal sensed by the first bio-signal sensing unit and a second bio-signal sensed by the second bio-signal sensing unit.
