    摘要: A MEMS thermal actuator device is provided that is capable of providing linear displacement in a plane generally parallel to the surface of a substrate. Additionally, the MEMS thermal actuator of the present invention may provide for a self-contained heating mechanism that allows for the thermal actuator to be actuated using lower power consumption and lower operating temperatures. The MEMS thermal actuator includes a microelectronic substrate having a first surface and at least one anchor structure affixed to the first surface. A composite beam extends from the anchor(s) and overlies the first surface of the substrate. The composite beam is adapted for thermal actuation, such that it will controllably deflect along a predetermined path that extends substantially parallel to the first surface of the microelectronic substrate. In one embodiment the composite beam comprises two or layers having materials that have correspondingly different thermal coefficients of expansion. As such, the layers will respond differently when thermal energy is supplied to the composite. An electrically conductive path may extend throughout the composite beam to effectuate thermal actuation. In one embodiment of the invention a two layer composite beam comprises a first layer of a semiconductor material and a second layer of a metallic material. The semiconductor material may be selectively doped during fabrication so as to create a self-contained heating mechanism within the composite beam. The invention also comprises a MEMS thermal actuator that includes two or more composite beams. The two or more composite beams may be disposed in an array or a ganged fashion, such that the multiple composite beams benefit from overall force multiplication and are therefore capable of greater and more linear displacement distances. The invention is also embodied in a method for fabricating the MEMS thermal actuators of the present invention.

The inventive actuator comprises at least two amagnetic supports (1, 2) arranged on the different planes, whereby forming a space (3) therebetween. The fixed magnetic part (5) is connected at least to one of the supports (1, 2). Each support (1, 2) is provided with a stop area (10, 20) for the mobile magnetic part (4) which is separated from the fixed magnetic part (5). The mobile magnetic part (4) is in levitation in the space (3) between two supports (1,2) as a result of a magnetic guidance produced by the fixed magnetic part (5) when it is not abutted against the stop area (10,20) of the supports (1, 2). The mobile magnetic part (4) is enable to take several stable magnetic positions when it is abutted against the supports (1, 2).

    摘要: The present invention is a thermally controlled switch with high thermal or electrical conductivity. Microsystems Technology manufacturing methods are fundamental for the switch that comprises a sealed cavity 213 formed within a stack of bonded wafers 201 , 202, wherein the upper wafer 202 comprises a membrane assembly 205 adapted to be arranged with a gap 21 1 to a receiving structure 210. A thermal actuator material 215, which preferably is a phase change material, e.g. paraffin, adapted to change volume with temperature, fills a portion of the cavity 213. A conductor material, providing a high conductivity transfer structure 216 between the lower wafer 201 and the rigid part 208 of the membrane assembly 205, fills another portion of the cavity 213. Upon a temperature change, the membrane assembly 205 is displaced and bridges the gap 21 1 , providing a high conductivity contact from the lower wafer 201 to the receiving structure 210.
