Abstract
ABSTRACTPiezoelectric energy harvesters are capable of sensing mechanical vibrations and converting them into usable energy to empower low-power microsystems. In this work, a novel seesaw cantilever structure-based broadband piezoelectric energy harvester has been designed using both lead-based and lead-free piezoelectric material. It has been observed that along with its structure dimensions and piezo material properties, a harvester’s load also determines its performance. An optimum load would yield maximum harvester power. The optimum value of a resistor generating peak power has been described in this work. The harvester is capable of producing a peak power of around 23 mW across a 0.14 MΩ load.
