Title:
SELF-POWERED TRAINABLE SWITCHING NETWORK
Document Type and Number:
WIPO Patent Application WO2002042873
Kind Code:
A3
Abstract:
A self-powered switching device using a prestressed flextensional electroactive member generates a signal for activation of a latching relay. The electroactive member has a piezoelectric element with a convex 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 of may be coupled to a transmitter for sending an RF signal to a receiver which actuates the latching relay.
