Title:
LONGITUDINAL PIEZOELECTRIC LATCHING RELAY
Document Type and Number:
Japanese Patent JP2003217422
Kind Code:
A
Abstract:

To provide a piezoelectrically actuated relay having latch capability.

This piezoelectricaly actuated relay 100 which switches and latches by means of a liquid metal 170 is disclosed. The relay 100 displaces a liquid metal drop 170 by a longitudinal displacement of a piezoelectric element 150 in extension mode and causes the liquid metal drop 170 to wet between at least one contact pad 160 on the piezoelectric element 150 or a substrate and at least one other fixed pad to close the switch contact. This motion of the piezoelectric element 150 is rapid and causes the imparted momentum of the liquid metal drop 170 to overcome the surface tension forces that would hold the bulk of the liquid metal drop 170 in contact with the contact pad 160 near the actuating piezoelectric element 150. The switch 100 latches by means of surface tension and the liquid metal 170 wetting to the contact pad 160.
