Abstract
A method of electromagnetic energy harvester is presented
of which both magnetic iron layer and coil layer are able to vibrate. The design is a sandwich structure composed of a magnet
a coil and a support layer. The modal
static and harmonic response are simulated by COMSOL. Through simulating
this structure can realize vibration energy acquisition in 6 vibration modes and 5 vibration directions at frequency of 400 Hz. Lay a good foundation for further process production.
