    Abstract: A radio frequency (RF) micro electromechanical system (MEMS) switch formed on a substrate (e.g., a CMOS substrate). The RF MEMS switch includes a micromechanical member including a flexible switch membrane configured to move between an on state and an off state of the RF MEMS switch. The flexible switch membrane includes a first set of fingers on a sidewall thereof to be vertically coupled with a second set of fingers formed at an output of the RF MEMS switch on the substrate, and an actuation member in operable communication with the micromechanical member and configured to thermally actuate the micromechanical member such that the first set of fingers electrically couple with the second set of fingers upon thermal actuation of the micromechanical member to enable transmission of an RF signal.

    Abstract: A micromechanical actuator includes a movable first spring element having metal and/or silicon. The first spring element is fitted at a first point and can move freely at a second point. A second spring element connected to the first spring element has silicon and is partially arranged on an electrically insulating material which is applied to a substrate. The second spring element is arranged at a distance from the substrate above the substrate on a first plane, and the first spring element is arranged above the second spring element on a second plane which is at a distance from the first plane such that the first and second spring elements can move with respect to the substrate. The actuator has a third spring element which is mechanically coupled to the first spring element. The elastic deformation of the second spring element can be induced by a length change of the third spring element.

    Abstract: A lithographically structured device has an actuation layer and a control layer operatively connected to the actuation layer. The actuation layer includes a stress layer and a neutral layer that is constructed of materials and with a structure such that it stores torsional energy upon being constructed. The control layer is constructed to maintain the actuation layer substantially in a first configuration in a local environmental condition and is responsive to a change in the local environmental condition such that it permits a release of stored torsional energy to cause a change in a structural configuration of the lithographically structured device to a second configuration, the control layer thereby providing a trigger mechanism. The lithographically structured device has a maximum dimension that is less than about 10 mm when it is in the second configuration.

    Abstract: A microactuator (10) providing an output force and displacement in response to an increase in thermal energy is disposed. The microactuator (10) may have a substantially straight expansion member (20, 22) with a first and a second end. The first end may be coupled to a base (12, 16) and a second end may be coupled to a shuttle (24). The expansion member is capable of elongating in a elongation direction. Elongation of the expansion member may urge the shuttle to translate in an output than the elongation direction. In certain embodiments, multiple expansion members are arrayed along one side of the shuttle to drive the shuttle against a surface. Alternatively, expansion members may be disposed on both sides of the shuttle to provide balanced output force. If desired, multiple microactuators may be linked together to multiply the output displacement and/or output force.
