<p>A locator device (10) having a transponder (12) 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 (12) has a battery (26) that is rechargeable by using the potential electrical energy generated by the body of the host organism. The preferred embodiment of the rechargeable transponder (12) uses a piezoelectric battery (26) that is to be implanted in an appropriate manner that would permit a large muscle (30) to act upon a piezoelectric element thereby converting the mechanical energy into electrical energy to provide a recharge to the battery (26).</p> |
