A multi-direction piezoelectric VEH based on circular arc structure
IEEE Sensors Journal（2019）
Abstract
In order to absorb the multi-directional vibration energy at the same resonance frequency, a novel multi-direction piezoelectric VEH is experimentally and theoretically investigated based on circular arc structure. The output voltage model and the output power model are established. Four different structures of this multi-direction piezoelectric VEH are designed and measured. The measured maximum ...
