摘要： An apparatus for and method of operating a thermal actuator for a micromechanical device, especially a liquid drop emitter such as an ink jet printhead, is disclosed. The disclosed thermal actuator comprises 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 barrier layer is bonded between the first and second deflector layers. The thermo-mechanical bender portion further has a base end and base end width, wb, adjacent the base element, and a free end and free end width, wf, adjacent the free end tip, wherein the base end width is substantially greater than the free end width. A first heater resistor is formed in the first deflector layer and adapted to apply heat energy having a first spatial thermal pattern which results in a first deflector layer base end temperature increase, ΔT1b, that is greater than a first deflector layer free end temperature increase, ΔT1f. A second heater resistor is formed in the second deflector layer and adapted to apply heat energy having a second spatial thermal pattern which results in a second deflector layer base end temperature increase, ΔT2b that is greater than a second deflector layer free end temperature increase, ΔT2f. Application of an electrical pulse to either the first or second heater resistors causes deflection of the cantilevered element, followed by restoration of the cantilevered element to an initial position as heat diffuses through the barrier layer and the cantilevered element reaches a uniform temperature. For liquid drop emitter embodiments, the thermal actuator resides in a liquid-filled chamber that includes a nozzle for ejecting liquid. Application of electrical pulses to the heater resistors is used to adjust the characteristics of liquid drop emission. The barrier layer exhibits a heat transfer time constant τB. The thermal actuator is activated by a heat pulses of duration τP wherein τP

摘要： A snap-through thermal actuator for a micro-electromechanical device such as a liquid drop emitter or a fluid control microvalve is disclosed. The snap-through actuator is comprised of 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 comprises apparatus adapted to apply a heat pulse to the deformable element which causes a sudden rise in the temperature of the deformable element. The deformable element initially bows farther outward in the first direction, then, due to thermomechanical torque's acting at the opposing anchor edges, reverses and snaps through the central plane to bow outward in a second direction toward the second layer, and then relaxes to the residual shape as the temperature decreases. The snap-through thermal actuator is configured with a liquid chamber having a nozzle, a fluid flow port to form a liquid drop emitter or a fluid control microvalve, or to activate an electrical microswitch. Heat pulses are applied to the deformable element by resistive heating or by light energy pulses.
