Modelling of Output Power Response for Switched Damping Electromagnetic Energy Harvester

The scavenging of electrical energy from surrounding environment has a number of attractions, and vibration energy is seen as one of the most potential sources. Switched damping is a method to improve the operational bandwidth of an electromagnetic energy harvester by alternatively switching the val...
