Abstract

Power supply is a bottle-neck problem of wireless micro-sensors, especially where the replacement of batteries is impossible or inconvenient. Now PIEZOELECTRIC material is being used to harvest vibration energy for self-powered sensors. However, the geometry of a PIEZOELECTRIC cantilever beam will greatly affect its vibration energy harvesting ability. This paper deduces a remarkably precise analytical formula for calculating the fundamental RESONANT FREQUENCY of V-SHAPED CANTILEVERs using Rayleigh-Ritz method. This analytical formula, which is very convenient for MECHANICAL ENERGY HARVESTER design based on PIEZOELECTRIC effect, is then validated by ABAQUS simulation. This formula raises a new perspective that, among all the V-SHAPED CANTILEVERs and in comparison with rectangular one, the simplest tapered cantilever can lead to maximum RESONANT FREQUENCY and highest sensitivity.
