Abstract
Design of an efficient energy harvester is now feasible as technology develops and a viable approach to solve this
need is to exploit the concept and application of a nonlinear design. In this letter, we conducted a comparative
analysis of linear and nonlinear piezoelectric energy harvesting from random impulsive excitations modelled by
white Poisson noise. It is shown that the harvester performance depends on both nonlinearity and properties
of ambient energy, and nonlinearity should be optimized for a given type of ambient vibration in order to
achieve efficient harvesting.
