Electric vehicle (EV, HEV, PHEV, FCEV) needs to use high voltage relay. The function is system protection from over current and short circuit by safety switch. The mechanism is that the electric current conduct on coil and generates magnetic field. It makes moving core and fixed core become a magnetic. After that, both of them pull each other by magnetic force. Finally, Relay switch from off to on...
and mode microelectromechanical systems piezoelectric energy harvesters (PEHs) were fabricated and compared to investigate their output powers converted from vibration. Both types of devices have the same dimensions in a cantilever structure and aim to effectively couple vibration from ambient conditions. The resonant frequencies of the cantilevers are 243 Hz. Two types of devices were...
