An electronic device is disclosed, including a housing having a front plate, a back plate facing the front plate, and a side frame surrounding a space defined between the front and back plates, a circuit board disposed within the housing, a module assembly disposed between the circuit board and the back plate, and electrically connected with the circuit board, wherein the module assembly includes: an optical sensor module including a flexible printed circuit board (FPCB) including a first surface and a second surface facing away from the first surface, a light emitting part disposed on the first surface of the FPCB, and a light receiving part disposed on the first surface spaced apart from the light emitting part, and a wireless charging module surrounding the FPCB of the optical sensor module, and at least partially coupled to the FPCB so as to be integrated with the FPCB.

Provided is a watch, including: an exterior case having electroconductivity; an operating member having electroconductivity, which is inserted into the exterior case through an opening formed through the exterior case, and which is configured to accept an operation performed by a user; and an electrostatic motor including: an electret substrate having an electret surface on which electret films being electrically charged are provided; a counter substrate, on which electrodes to be arranged so as to be opposed to the electret films are provided; and a rotary shaft configured to rotate the electret substrate and the counter substrate relative to each other, wherein the operating member and the exterior case are electrically continuous with each other via a conduction path formed so as to avoid overlapping with the electret surface in plan view.

The present disclosure provides wearable electronic devices with thermoelectric devices. The wearable electronic device may comprise a user interface for displaying information to a user. The thermoelectric device may comprise a heat collecting unit, a thermoelectric element, and a heat expelling unit. During use, the thermoelectric element may generate power upon the flow of thermal energy from the heat collecting unit, across the thermoelectric element, and to the heat expelling unit.

A kinetically-powered wrist-worn electronic device is apparatus that includes a portable computing device, a wrist strap, a weight, and a generator. The portable computing device runs an operating system responsible for managing and distributes computing resources to various application software on the present invention. A wireless communication module accesses a wireless local area network (WLAN) or a wide area network (WAN) and enables the portable computing device to communicate with external computing devices. The wrist strap secures the portable computing device onto the wrist of the wearer. The weight uses a swinging mass which is designed to oscillate whenever the wearer moves his or her wrist. The generator harnesses and transforms the kinetic energy generated by the oscillating weight into usable electrical energy to power the portable computing device. The electrical energy is stored in a portable power which transfers the electrical energy to the portable computing device.

A variety of improvements to portable electronic devices are disclosed, particularly electronic devices designed for use in and around water. The improvements include a more secure interface jack, improved waterproofing techniques, improved battery stability, and improved device functionality. One or more of the disclosed improvements may be incorporated into a variety of portable electronic devices.
