Piezoelectric energy harvesting from colored fat-tailed uctuations: an electronic analogy

Abstract

Aiming to optimize piezoelectric energy harvesting from strongly colored fat-tailed uctuations, we have recently studied the performance of a monostable inertial device under a noise whose statistics depends on a parameter q (bounded for q < 1, Gaussian for q = 1, fat-tailed for q > 1). We have studied the interplay between the potential shape (interpolating between square-well and harmonic-like behaviors) and the noise’s statistics and spectrum, and showed that its output power grows as q increases above 1. We now report a real experiment on an electronic analog of the proposed system, which sheds light on its operating principle.
