A locator device having a transponder subcutaneously implanted in a person or animal that is to be periodically monitored in the event of emergency, abduction and other such situations. The transponder has a battery that is rechargeable by using the potential electrical energy generated by the body of the host organism. The preferred embodiment of the rechargeable transponder uses a piezoelectric battery that is to be implanted in an appropriate manner that would permit a large muscle to act upon a piezoelectric element thereby converting the mechanical energy into electrical energy to provide a recharge to the battery. |
