Harvesting Energy Using a Lightweight Piezo-Composite Actuator (LIPCA)

Nam Seo Goo

Abstract


Energy can be reclaimed and stored for later use to recharge a battery or power a device through a process called energy harvesting. Piezoelectric actuators are being widely investigated for use in harvesting energy from motion such as body movement and machine vibration. Along with bare PZT, RAINBOW and THUNDERTM, LIPCA has been developed for high performance actuators suitable for control surface and active vibration control of aerospace and submarine structures. This paper introduces an experiment for using LIPCA on harvesting energy to investigate its ability to convert oscillatory mechanical energy into electrical energy. LIPCA consists of layers of carbon/epoxy, PZT ceramic and glass/epoxy. Through this investigation, the potential of using LIPCA and PZT for harvesting energy from the vibration excitation was studied.
