ABSTRACT:
A snap-through thermal actuator for a micro-electromechanical device is provided. The snap-through actuator includes a base element formed with a depression having opposing anchor edges which define a central plane. A deformable element, attached to the base element at the opposing anchor edges, is constructed as a planar lamination including a first layer of a first material having a low coefficient of thermal expansion and a second layer of a second material having a high coefficient of thermal expansion. The deformable element is formed to have a residual shape bowing outward from the central plane in a first direction away from the second layer. The snap-through thermal actuator further includes apparatus adapted to apply a heat pulse to the deformable element which causes a sudden rise in the temperature of the deformable element.
