The Use of Piezoelectric Ceramics for Electric Power Generation Within Orthopedic Implants
2005
IEEE/ASME transactions on mechatronics
This paper presents the results of tests that demonstrate the feasibility of using piezoelectric (PZT) ceramics to generate in vivo electrical energy for orthopedic implants. Sensors encapsulated within implants could provide in vivo diagnostic capabilities such as the monitoring of implant duty (i.e., walking) cycle, detecting abnormally asymmetric or high forces, sensing misalignment and early loosening, and early detection of wear. Early diagnosis of abnormalities or impending failure is
