Abstract

The Interdisciplinary Consulting Corporation proposes a technological advancement of current state-of-the-art acoustic energy harvester for harsh environment applications. Due to the advancement of propulsion systems and increasing power requirements, the development of a renewable energy source is ideal to overcome the related issues seen in systems powered by batteries (limited lifespan, recharge issues, accessibility and replacement).We propose the innovation of a mesoscale, acoustic energy harvester with a Helmholtz resonator and a piezoelectric composite backplate using high temperature materials. Additionally, a high temperature power rectifying circuitry will be developed to convert the output of the time-varying output of the energy harvester into a useable form. The target application is to power feedback or embedded sensor systems to enable self-sustaining functionality to the devices.
