Electromechanical analogy for d33 piezoelectric harvester power calculations

This paper combines both the well-known power transfer and electromechanical coupling analogy theories for calculating the electrical power output of d₃₃-based piezoelectric harvesters. The proposed methodology utilized the direct mechanical-to-electrical analogy, electromagnetic and power system theories to develop analytical models to compute the power output taking into account the dimensions and material properties of the piezoelectric generator. The developed method has been experimentally validated and it was found that the current technique provides significant additional information that crucial for enhancing the device design and operation in a straightforward manner when compared to other conventional reported methods.
