A study of the micro power generators with a coil and a magnet using vibration of low frequencies
초록
We have fabricated a micro power generator which changes vibrational energy into useful energy. With vibrating a magnet on the surface of a winding coil, the micro power generator produce alternating voltage. We have changed the vibrational frequency from 0.5Hz to 10Hz. AC voltage of
