Energy Scavenging from Vibrations

Author: Dr. Yanfei Liu

In this project, students learn that energy can be harvested or scavenged from the surrounding environment, in sufficient quantities for use in powering embedded systems. In the laboratory, students design and build a system using Lego pieces and a piezoelectric buzzer that harvests energy from vibrations and uses the energy to charge a battery. Along the way, the students learn about dc motors, cams and gears, piezoelectric material, and circuits for charging.
