    Abstract: A method of forming a surface of micrometer dimensions conforming to a desired contour for a MEMS device, the method comprising providing a crystalline silicon substrate with a recess in an upper surface, providing a thinner layer of crystalline silicon over the upper surface of the substrate, fusion bonding the layer to the substrate under vacuum conditions, and applying heat to the layer and applying atmospheric pressure on the layer, such as to plastically deform the diaphragm within the recess to the desired contour. The substrate may form the fixed electrode of an electrostatic MEMS actuator, operating on the zip principle.

    Abstract: In embodiments of the present invention, a microelectromechanical actuator includes a beam having respective first and second ends attached to a substrate and a body disposed between the first and second ends having a sinuous shape. The body includes a portion operative to engage a object of actuation and apply a force thereto in a direction perpendicular to the beam responsive to at least one of a compressive force and a tensile force on the beam. The sinuous shape may be sinusoidal, e.g., a shape approximating a single period of a cosine curve or a single period of a sine curve. The beam may be thermally actuated or driven by another actuator. In other embodiments, a rotary actuator includes first and second beams, a respective one of which has first and second ends attached to a substrate and a body disposed between the first and second ends. Each body includes first and second oppositely inflected portions. The bodies of the first and second beams intersect one another at points at which the first and second oppositely inflected portions of the first and second bodies meet. The bodies of the first and second beams are operative to engage the object of actuation and rotate the object of actuation around the point of intersection responsive to at least one of compressive force and tensile force on the first and second beams. Related methods are also described.
