Development of Gyroscopic Power Generator

In order to solve the energy supply problem for ubiquitous equipments, a gyroscopic power generator is proposed which utilizes kinetic energy of human movement. In the generator, a rotor increases spinning velocity by the precession and friction caused by input vibration. In this paper, first, the structure and the power generation principle of the generator are explained. Next, an analytical method of the rotor movement is presented and validity of the analysis is verified by the experiment using a prototype generator. Finally, the amount of the maximum power generation is forecasted to show the potential ability of the generator.
