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.
摘要(中):
用于微机电装置的热致动器,特别是用于喷墨打印的液滴发射器,包括基座元件(10)和可移动元件(10)。 可移动元件包括具有低导热材料的阻挡层(22),其结合在第一和第二层(24,26)之间。 第一层由具有高热膨胀系数的第一材料构成。 第二层具有高导热率和杨氏模量。 提供了一种适于将热脉冲直接施加到第一层的装置,引起第一层的热膨胀和可动元件从第一位置到第二位置的偏转,随后将可移动元件朝向第一位置松弛,作为 散热通过阻挡层扩散到第二层。
