摘要： An apparatus for a liquid drop emitter, especially for use in an ink jet printhead, is disclosed. A chamber filled with a liquid, a nozzle and a thermo-mechanical actuator (15), extending into the chamber from at least one wall of the chamber is disclosed. A movable element (20) of the thermo-mechanical actuator is configured with a bending portion which bends when heated, the bending portion having at least one actuator opening (32) for passage of the liquid. Apparatus is adapted to apply heat pulses to the bending portion resulting in rapid deflection of the movable element, ejection of a liquid drop, and passage of liquid through the at least one actuator opening.

摘要： A thermal actuator for a micro-electromechanical device, especially a liquid drop emitter for ink jet printing, comprises a base element (10) and a movable element (10). The movable element includes a barrier layer (22) having low thermal conductivity material, bonded between first and second layers (24, 26). The first layer is constructed of a first material having a high coefficient of thermal expansion. The second layer has high thermal conductivity and Young's modulus. An apparatus is provided adapted to apply a heat pulse directly to the first layer, causing a thermal expansion of the first layer and deflection of the movable element from a first to a second position, followed by relaxation of the movable element towards the first position as heat diffuses through the barrier layer to the second layer.
