We have developed an electret-type MEMS environmental vibration energy harvester that does not require electret charging processing. This is the result of joint research between Ritsumeikan University and Chiba University.

Ritsumeikan University made a joint press release with Chiba University and JST (Japan Science and Technology Agency) on the research results of MEMS vibration energy harvester published in Applied Physics Letters.
