generator system succeeded in generating the output power more than four times larger
than conventional products of the same size. This is nearly electromagnetic generator is
suitable for lower frequency and long stroke. As the resonant system is created by the
coil-springs, it is possible to design for specific resonant frequency depending on the usage.
Applications:
Power source for remote control, Electric charger for a mobile equipment, Flash light for
emergency, Power source for active RFID and Power source for ocean buoy.
Product lineup:
φ14mm×L50mm (Size AA)
