An Implantable Wireless Inductive Sensor System Designed To Monitor Prosthesis Motion in Total Joint Replacement Surgery.

Currently, the most common method for detecting prosthetic implant loosening is imaging. Unfortunately, imaging methods are imprecise in detecting the early signs of implant loosening. This paper describes a new wireless inductive proximity sensor system for detecting early implant loosening. The loosening of the implant is accurately detected by analyzing the electromagnetic field generated by th...
