Abstract
A Micro-Electro Mechanical device includes a movable mechanical structure and a bias mechanism. A bubble confinement region is defined by at least a portion of the movable mechanical structure. A bubble generation mechanism produces a bubble within the bubble confinement region. The bubble displaces the movable structure and alters the configuration of the bias mechanism, thereby producing useful work.
