Conventional vibration generators have used simple pendulums. Their maximum generating power was less than several 10 mW. When a rotating body is given a pitching vibration, a gyro effect is caused and a large torque is obtained. The gyro generators use this effect and generate more than 1W. There are 2 types of gyro generators. The one spins a rotor by a motor and the other by a precession friction force. The motor driven type has an advantage oft working under arbitrary vibrations. The friction driven type has an advantage of a simple structure. This paper explains principles of gyro generators and our related research.
