Elie Lefeuvre has been a Professor with the University of Paris-Sud since 2010. From 2001 to 2007, he was an Associate Professor with the National Institute for Applied Sciences (Lyon, France), where he conducted research on energy harvesting, vibration control, and structural health monitoring systems for aerospace applications. Then, he oriented his work in the field of MEMS, when he was hired by University of Paris-Sud in 2007. He currently heads the Energy Harvesting research team at the Center for Nanoscience and Nanotechnology, a joint research unit of the CNRS and University of Paris-Sud. He has authored more than 160 research papers and patents on piezoelectric and electrostatic transducers, MEMS and interface circuits for energy harvesting. His current research focuses in particular on the topic of biomechanical energy harvesting for medical implant applications.
