Abstract
We consider the planform of a cantilever piezoelectric vibrating energy harvester (PVEH), that has an edge block which is patterned only in the device layer. We derive an analytic expression of the planform, which ensures an optimal performance of the cantilever PVEH. The contours of the optimal planform are described by Bessel functions, and the predictive capabilities of our new model are demonstrated by the good agreement with finite elements simulations.
