    Abstract: A haptic actuator device includes a surface with a mechanical property responsive to localized temperature changes. The surface can include a layer or sheet comprising a shape-memory material. The haptic actuator device can further include an actuator configured to selectively deform a plurality of regions in the sheet; and a temperature controller adapted to control the temperatures of the plurality of regions. A method of localized actuation includes selectively controlling the temperatures of the plurality of regions to be above a shape-memory transition temperature of the shape-memory material; selectively deforming at least one of the regions; while maintaining the deformation of the at least one region, lowering the temperature of the at least one region to below the shape-memory transition temperature; subsequently withdrawing the applied stress; and thereafter heating the at least one region to above the shape-memory transition temperature, causing the region to return to its pre-deformation shape.

    Abstract: The present invention relates to a design and microfabrication method for microgrippers that are capable of grasping micro and nano objects of a large range of sizes and two-axis force sensing capabilities. Gripping motion is produced by one or more electrothermal actuators. Integrated force sensors along x and y directions enable the measurement of gripping forces as well as the forces applied at the end of microgripper arms along the normal direction, both with a resolution down to nanoNewton. The microfabrication method enables monolithic integration of the actuators and the force sensors.

    Abstract: The invention relates to the preparation of multilayer microcomponents which comprise one or more films, each consisting of a material M selected from metals, metal alloys, glasses, ceramics and glass-ceramics.The method consists in depositing on a substrate one or more films of an ink P, and one or more films of an ink M, each film being deposited in a predefined pattern selected according to the structure of the microcomponent, each film of ink P and each film of ink M being at least partially consolidated before deposition of the next film; effecting a total consolidation of the films of ink M partially consolidated after their deposition, to convert them to films of material M; totally or partially removing the material of each of the films of ink P. An ink P consists of a thermoset resin containing a mineral filler or a mixture comprising a mineral filler and an organic binder. An ink M consists of a mineral material precursor of the material M and an organic binder. The inks are deposited by pouring or by extrusion.

    Abstract: A representative embodiment of the invention provides a thermal actuator for a MEMS-based relay switch. The thermal actuator has an “active” arm that is movably mounted on a substrate. The “active” arm has (i) a thermal expansion layer and (ii) a resistive heater that is electrically isolated from the thermal expansion layer. The thermal expansion layer is adapted to expand in response to a temperature change induced by a control current flowing through the resistive heater, thereby bending the “active” arm and moving that arm with respect to the substrate. Due to the fact that mechanical and electrical characteristics of the “active” arm are primarily controlled by the thermal expansion layer and the resistive heater, respectively, those characteristics can be optimized independently to obtain better operating characteristics for MEMS-based relay switches of the invention compared to those attained in the prior art.

    Abstract: The present invention provides a bi-directional microelectromechanical element, a microelectromechanical switch including the bi-directional element, and a method to reduce mechanical creep in the bi-directional element. In one embodiment, the bi-directional microelectromechanical element includes a cold beam having a free end and a first end connected to a cold beam anchor. The cold beam anchor is attached to a substrate. A first beam pair is coupled to the cold beam by a free end tether and is configured to elongate when heated thereby to a greater temperature than a temperature of the cold beam. A second beam pair is located on an opposing side of the cold beam from the first beam pair and is coupled to the first beam pair and the cold beam by the free end tether. The second beam pair is configured to elongate when heated thereby to the greater temperature.
