Abstract

The wireless mouse device free of a battery of the present invention is integrated to have a power processing circuit and a sensing coil. A receiver unit for receiving the signals of the mouse is integrated to have therein an alternative signal circuit and an emitting/receiving coil, so that the receiver unit can generate high frequency signals emitted via an emitting/receiving coil; the mouse can receive harmonic vibrations of the high frequency signals through the sensing coil, and the power processing circuit will make pressure-multiplication processing for the harmonic vibrations received to make the latter an electric power for driving the mouse.
