Weiwei Xu is a postdoctoral researcher at the University of Washington in Seattle, where she works on the research and development of sensor systems for measuring dental implant stability. She earned her Ph.D. in Mechanical Engineering from the University of Washington in 2019, with a focus on the fabrication, characterization, and application of PZT thin-film sensors and actuators. With over a decade of experience in mechanical engineering, Weiwei has worked extensively in sensor technology, particularly in dental implant stability measurement. Her research expertise also includes piezoelectric thin film sensors and actuators, printable flexible electrodes, microelectromechanical systems (MEMS) and microfabrication, structural health monitoring (SHM), vibration analysis, and finite element simulations.
