Abstract

Devices, systems, and methods for selectively activating medical devices are disclosed. A medical device in accordance with an illustrative embodiment includes an energy storage device, an acoustic transducer configured to convert an acoustic signal into an electrical signal, a signal detector configured to generate a trigger signal when the electrical signal exceeds a specific threshold established by a biasing element, a control circuit, and an activation/deactivation switch configured to switch the medical device between an inactive state and an active state in response to the trigger signal.
