In order to solve energy supply problems in ubiquitous information systems, a new driving technique for the gyroscopic power generator has been developed. The generator was made to work as a motor, Which was started automatically by providing an initial velocity. The ability to generate 0.7 W of power from vibration, the frequency of which is as low as 1 Hz, as well as the ability to charge 5-cells of NiMH batteries were demonstrated.
