Electronically droplet energy harvesting using piezoelectric cantilevers
Abstract:
A report is presented on free falling droplet energy harvesting using piezoelectric cantilevers. The harvester incorporates a multimorph clamped-free cantilever which is composed of five layers of lead zirconate titanate piezoelectric thick films. During the impact, the droplet kinetic energy is transferred into the form of mechanical stress forcing the piezoelectric structure to vibrate. Experimental results show energy of 0.3 J per droplet. The scenario of moderate falling drop intensity, i.e. 230 drops per second, yields a total energy of 400 J.
