Abstract
A micromechanical device capable of providing out-of-plane motion and force generation in response to an in-plane strain applied to the device is provided. Embodiments of the present invention comprise one or more islands that are operatively coupled with one or more hinges. The hinges are operative for inducing rotation of the islands when a lateral strain is applied to the structure. In some embodiments, the hinges are also electrically conductive such that they enable electrical communication between the one or more islands and devices external to the structure. Some embodiments of the present invention are particularly well suited for use in biological applications. Some devices in accordance with the present invention are fabricated using conventional planar processes, such as flex-circuit fabrication techniques.
