Abstract: A self-powered switching device is provided. In embodiments, the device uses a prestressed flextensional electroactive member to generate a signal for activation of a latching relay. The electroactive member has a piezoelectric element with a convex face and a concave face that may be compressed to generate an electrical pulse. The flextensional electroactive member and associated signal generation circuitry can be hardwired directly to the latching relay or may be coupled to a transmitter for sending an RF signal to a receiver which actuates the latching relay.
