TLDR
In this paper, a piezoelectric relay with less material than conventional P2P relays is described, where the contacts are touching with essentially no force applied between the contacts when no power is applied to the relay.Abstract:
A piezoelectric relay requiring less piezoelectric material than conventional piezoelectric relays is disclosed. The relay differs from conventional relays in that the contacts are touching with essentially no force applied between the contacts when no power is applied to the relay.read more
