  Aiming 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 (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.
