    Abstract: A microvalve device includes a body, a valve element supported for movement relative to the body, and an actuator operatively coupled to the valve element for moving the valve element in a normal range of travel. A travel limiting structure operatively cooperates with at least one of the valve element and the actuator to effectively limit the magnitude of movement of the valve element or the actuator outside the normal range of travel to prevent failure of the body, the valve element, or the actuator due to exceeding failure stress limits. A method of forming a microvalve with such a travel limiting structure is also disclosed.

    Abstract: A MEMS hysteretic thermal actuator may have a plurality of beams disposed over a heating element formed on the surface of the substrate. The plurality of beams may be coupled to a passive beam which is not disposed over the heating element. One of the plurality of beams may be formed in a first plane parallel to the substrate, whereas another of the plurality of beams may be formed in a second plane closer to the surface of the substrate. When the heating element is activated, it heats the plurality of beams such that they move the passive beam in a trajectory that is neither parallel to nor perpendicular to the surface of the substrate. When the beams are cooled, they may move in a different trajectory, approaching the substrate before moving laterally across it to their initial positions. By providing one electrical contact on the distal end of the passive beam and another stationary electrical contact on the substrate surface, the MEMS hysteretic actuator may form a reliable electrical switch that is relatively simple to manufacture and operate.
