Base-vibrated Parabolically Tapered Piezoelectric Vibration Energy Harvester: Electromechanical Modelling and Experimental Validation
This paper presents a parabolically tapered piezoelectric vibration energy harvester which aims to replace conventionally used batteries in low-power microelectronics and sensor applications. The presented design minimizes the sporadic stress distribution, common in the piezoelectric energy harvesters. The nonlinear be...
