ABSTRACT:
An apparatus for and method of operating a thermal actuator for a micromechanical device, especially a liquid drop emitter for use in an ink jet printhead, is disclosed. The disclosed thermal actuator includes a base element and a cantilevered element including a thermo-mechanical bender portion extending from the base element to a free end tip. The thermo-mechanical bender portion includes a barrier layer constructed of a dielectric material having low thermal conductivity, a first deflector layer constructed of a first electrically resistive material having a large coefficient of thermal expansion, and a second deflector layer constructed of a second electrically resistive material having a large coefficient of thermal expansion wherein the baffler layer is bonded between the first and second deflector layers.
