A Wireless Battery-Less Computer Mouse with Super Capacitor Energy Buffer
This paper proposes a novel wireless computer mouse power supply system which runs off a standard USB port and eliminates the use of batteries completely. The system uses a soft switched current-fed push-pull converter for DC to AC conversion. The AC current, which flows through a disk coil embedded into a mouse-pad, provides a time varying magnetic field that transfer power to a power pick-up coil located within the mouse, through magnetic induction. This power, which was tuned-up and regulated by an advanced voltage control method- dynamic detuning control, has proven to be able to provide sufficient power to drive a wireless mouse. Furthermore, an energy buffer system is added which backs up and allocates the induced power to allow mouse operation and energy storage to occur in a coordinated way. This system allows the mouse to sustain in operation even when it is moved away from the mouse-pad. A minimum duration of 2 minutes was achieved when the mouse was constantly active.
