Abstract (en)
[origin: WO2011022750A1] A thermal bend actuator comprises an active beam for connection to drive circuitry and a passive beam mechanically cooperating with the active beam. When a current is passed through the active beam, the active beam expands relative to the passive beam resulting in bending of the actuator. The passive beam comprises a first layer comprised of silicon nitride and a second layer comprised of silicon dioxide. The second layer is sandwiched between the first layer and the active beam to provide thermal insulation for the first layer.
