ENERGY HARVESTER

摘要

An energy harvester according to the present invention comprises a housing and a mass part installed on the housing to vibrate in response to external vibration at a multi-degree of freedom. The mass part includes a core with a coil. The housing has a magnetic part. Therefore, the energy harvester harvests energy by relatively moving the core with the magnetic part to generate an induced current on the coil inside the core as the mass part vibrates at a multi-degree of freedom.
