Abstract
In at least one illustrative embodiment, a microelectromechanical system (MEMS) includes a composable piezoelectric actuator electrically coupled to a terminal. In response to a voltage applied across electrodes of the actuator, a piezoelectric rod moves from an initial position to a displaced position. In an embodiment, the MEMS includes two terminals, a resistive element is coupled between the terminals, and when in the displaced position the rod contacts one of the terminals. In an embodiment, the MEMS includes three terminals, and when a threshold voltage is applied to one of the terminals, the rod moves to the displaced position and allows current to flow between the other two terminals. In an embodiment, the MEMS includes a primary set of actuators that are mechanically but not electrically connected to a secondary set of actuators. An output terminal is coupled to the second set of actuators. Other embodiments are described and claimed.
