Shaped like a battery on the outside, the energy harvester is equipped with an electromagnetic induction generator and a 500-mF capacitor for storage. It generates about 100-mW of power which is suitable for small devices; the remote control, for instance, only needs between 40-mW and 100-mW of power to operate. The output of the AA-size generator is 10 to 180-mW, providing power at 1.6- and 3.2-volts, while an AAA unit that generates 2.7-V has also been produced. There is no need to keep replacing AA and AAA batteries with this environmentally-friendly kinesthetic or vibration electricity generator.
