Optionally, the actuator includes a monolithic crystal actuator. Preferably, the monolithic crystal actuator includes a crystal having zero grain boundaries. The monolithic crystal actuator also includes a plurality of thin flexure structures. The monolithic crystal actuator further includes a plurality of metallic electrodes disposed on inside or outside surfaces, or a combination thereof, of the plurality of thin flexure structures.

Abstract: A plain bearing slide system has a carriage mounted on a slide by use of bearing pads. Each bearing pad is coated with a layer of polymeric material having a convex surface, and is arranged to ride on a counterface. The combined thickness of the layer and a layer providing the counterface is such that the difference between the static and dynamic coefficients of friction is substantially less than the difference associated with the material when used in bulk bearings. A slide system using PTFE, and with a combined thickness of the layers of 2 to 3 micrometers, operated as a measuring instrument under ambient conditions such that the PTFE is substantially non-eroding, has proved capable of providing measurements to an accuracy of 0.05 nanometers.

Abstract: A small-scale positioning device employing a platform, a levering mechanism and a floating actuator device. The platform is movably attached to a fixed frame by a lever, a pair of levers, or more. The floating actuator device is coupled between at least one lever and the platform. When the actuator device is activated, it generates a force on the platform and an equal but opposite force on the levering mechanism, causing one or more levers to rotate around their respective fulcrums, thereby controlling the position of the movable platform relative to the fixed frame. The amount of displacement of the platform is dependent upon the effective expansion or contraction of the actuator device and the lever ratio. If the pair of levers are symmetrical, then motion is created in only a single degree of motion. Flexures may be included to prevent motion in unwanted directions.
