Outline of Final Research Achievements

Two types of vibrational power generators were developed that increase output power by moving a pendulum in high speed. The first type rotates pendulum by a motor and gives rotational vibration to it. Its amplifying mechanism is the same as that of spinning gyroscopes. The generator works under any vibration and produced 0.2W at most. The second type gives a beam a bending and a twisting vibrations. Its amplifying mechanism is the same as that of vibrational gyroscopes. The generator produced vibrational amplitude of 1.5 times larger than that without bending vibration.
