iming to optimize piezoelectric energy harvesting from strongly colored fat-tailed fluctuations, 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 (interpolatingbetween 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.
