Abstract
A MEMS piezoelectric power harvesting device, a unimorph PZT cantilever and arrays with an integrated Si proof mass was designed. Pt/PZT/Pt/Ti/SiO2 multilayered films were deposited on Si or SOI substrates and then the cantilevers were patterned and released by inductively coupled plasma (ICP) reactive ion etching (RIE). The fabricated devices demonstrate that the monolithic device (mono-cantilever beam) can produce around 2 – 4 μ W at 1-g condition corresponding to 1000 – 4000 μ W/cm3. The typical current generated from such device ranges around 5 – 10 μ A. The array consisting of 10 cantilever beams was able to demonstrate about 12 μ W power generation comprising of 120 μ A and 100 mV.
