    Abstract: Briefly, in accordance with one embodiment of the invention, a switch structure or the like such as a valve, motor, or optical switch, may be constructed based on a thermoresponsive polymer. At a first temperature the thermoresponsive polymer may be in a first volume state, and at a second temperate the thermoresponsive polymer may be in a second volume state. The change in volume of the thermoresponsive polymer may be operative to push or pull the mechanical structures of the switch, valve, motor, optical switch, and so on, to effectuate operation of the structures.

    Abstract: A method for producing a corrosion-resistant channel in a wetted path of a silicon device enables such device to be used with corrosive compounds, such as fluorine. A wetted path of a MEMS device is coated with either (1) an organic compound resistant to attack by atomic fluorine or (2) a material capable of being passivated by atomic fluorine. The device is then exposed to a gas that decomposes into active fluorine compounds when activated by a plasma discharge. One example of such a gas is CF4, an inert gas that is easier and safer to work with than volatile gases like ClF3. The gas will passivate the material (if applicable) and corrode any exposed silicon. The device is tested in such a manner that any unacceptable corrosion of the wetted path will cause the device to fail. If the device operates properly, the wetted path is deemed to be resistant to corrosion by fluorine or other corrosive compounds, as applicable.

    Abstract: An actuator assembly and method for making and using an actuator assembly. In one embodiment, the assembly includes an actuator body having an actuator channel with a first region and a second region. An actuator is disposed in the actuator channel and is movable when in a flowable state between a first position and a second position. A heater is position proximate to the actuator channel to heat the actuator from a solid state to a flowable state. A source of gas or other propellant is positioned proximate to the actuator channel to drive the actuator from the first position to the second position. The actuator has a higher surface tension when engaged with the second region of the channel than when engaged with the first region. Accordingly, the actuator can halt upon reaching the second region of the channel due to the increased surface tension between the actuator and the second region of the channel.
