Abstract
Technologies for a microelectromechanical system (MEMS) made up of composable piezoelectric actuators is disclosed. An elongated piezoelectric rod is disposed between a top and a bottom electrode. The top electrode runs along one edge of the top of the piezoelectric rod for a first segment, then runs along the other edge of the top of the piezoelectric rod for the a second segment. When a voltage is applied across the electrodes, the piezoelectric rod bends in a first direction for the first segment and in a second direction opposite the first for the second segment, displacing the tip of the rod. Several such rods can be joined in parallel and/or series, allowing for large-scale systems to be composed.
