Abstract

In order to power microcontrollers and low-power wireless communication hardware to monitor and control remotely located processes, a piezoelectric rotary energy harvester was designed. A ring shaped sheet of polyvinylidene fluoride (PVDF) separated into four poled quadrants is bonded to an elastic aluminum substrate. Spinning low-friction impingers deflect the stationary disk and cause the piezoelectric segments to slightly deflect and generate voltage. The design’s voltage responses are modeled using MAPLE and then verified through prototyping and proper data acquisition. The effect of the number and configuration of segments, the magnitude of the force applied, and the addition of alternating polarity within the PVDF segments to generate a traveling wave are additionally examined.
