Resistive Short-Circuit (RSC) strategy for wideband piezoelectric energy harvesting

Résumé

This paper introduces a new energy harvesting technique dedicated to highly coupled piezoelectric energy harvesters (PEH). This harvesting technique is useful to compensate for the mismatch between the input frequency and the resonant frequency of the PEH, enabling impedance matching. The proposed extraction technique, called "Resistive Short-Circuit" technique (RSC) is similar to the "Resistive Capacitive" technique (RC) in terms of bandwidth and power performances when applied to highly coupled PEHs. In this paper, we validate the implementation of the RSC technique. The power output of the RSC technique matches the RC one. However, the space requirement is greatly reduced, as only two NMOS are needed versus a full capacitor bank. Optimal parameters of the RSC model match the experimental ones in term of short circuit duration and optimal load.
