Systems and methods for monitoring implantable devices for detection of implant failure utilizing wireless in vivo micro sensors

摘要

An implantable position detecting system is configured to detect a position of an implantable device with respect to a body structure. The system includes at least one proximity measuring transducer configured to be implanted on the body structure a distance from the implantable device, the at least one proximity measuring transducer being configured to receive energy from an external electromagnetic field generated by an external sensing interface, wherein the at least one proximity sensor is configured to emit an emitted signal responsive to the electromagnetic energy and to receive distance information comprising a sensing signal that is responsive to the distance from the implantable device.
