Abstract

The paper deals with the performances of rainfall energy harvesting by means of piezoelectric transducers. Different studies agree on the level of suitable generated voltage on the electrodes of a piezoelectric transducer subjected to rainfall, but a complete characterization on the supplied power is still missing. This work, in order to limit optimistic forecasts, takes into account the behaviour of the transducers subjected to real and artificial rainfall, condition that has shown promising behaviour in laboratory. In order to increase the energy harvesting and define its limits different loads have been taken into account. Two commercial transducers have been considered: a lead zirconate titanate and polyvinylidene difluoride transducer.
