Dr. Yanfei Liu

Dr. Yanfei Liu received a BS (1996) in Electrical Engineering from Shandong Institute of Architecture and Engineering, Jinan, China, a MS (1999) in Electrical Engineering from the Institute of Automation, Chinese Academy of Sciences, Beijing, China, and a PhD (2004) in Electrical Engineering from Clemson University in South Carolina. In 2005 she joined the Department of Engineering at Indiana University – Purdue University Fort Wayne (IPFW) as an assistant professor. Dr. Liu’s Ph.D. work was on vision guided dynamic manipulation for industrial robots. Her current research focuses on autonomous mobile robots and distributed sensing. Dr. Liu’s group works with various types of robots for different applications. She is also particularly interested in distributed sensing using low-cost, low-power consumption smart cameras with wireless capabilities.

Energy Scavenging from Vibrations

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.
