Abstract
Techniques are disclosed for detecting a functionality of a medical device implanted within the human body. A testing method includes delivering power to and measuring an electrical response of ion exchange polymer metal composite (IPMC) material that is part of the implant device in a first testing interval. Power can be transmitted at radio frequencies which penetrate tissue such that direct contact with the implant device is not required. Following the first testing interval, the implant can be powered continuously for a predetermined time. The implant can be powered in a second testing interval and the electrical response can again be measured. A functionality of the implant device can be detected based on the electrical response in the first and second testing intervals. The testing method can be practiced in connection with a handheld device, a retainer, or other suitable apparatus.
