Energy harvesting capabilities and bandgaps of locally resonant piezoelectric metamaterial panels with self-extraction synchronized circuit

Abstract

In this paper, we present an investigation into the unique energy harvesting and bandgap features of a piezoelectric locally resonant metamaterial conical panel fitted with a self-extraction synchronized circuit. In this paper, the energy harvesting and bandgap of the structure employ a selfextraction synchronized circuit. An elastic-electromechanical model will be developed using firstorder conical panel theory (FSDT) for investigation. Herein, the dynamic behavior of the metamaterial conical panels and the bandgap properties created by the locally resonant modes are explored, while research based on the differential cubature method and integral quadrature method is underway. Energy harvesting capability will also be examined, and numerical results will be validated with the help of available experimental data. The conclusion from this article showed that the bandwidth can nearly be doubled from 46.9 to 96.8 with the inclusion of the high-capacity capacitor, hence proving that it has an important effect on bandwidth, while the introduction of an inductor extended it from 449.5 Hz to 513 Hz, elaborating a 35 % raise against the setup without an inductor. Moreover, for the 10 mm long piezoelectric patch, the thickness impacts quite a little on the output voltage, with a minimum of 15.17 v at a thickness of 0.0375 mm. Then, for the 32.1 mm Blaze length, there is a critical turn in the trend for the output voltage from the rise to fall back.
