A piezoelectric multiplexer includes an actuator and multiple piezo-morph beams. The actuator includes an actuator conducting head and an actuator stem, and each piezo-morph beam includes a conducting beam contact head and a beam stem manufactured out of piezo-morph material. A control voltage is selectively applied to electrical contacts coupled to the beam stems to create a piezoelectric effect that bends the selected piezo-morph beam and creates an electrical connection between its contact head and the conducting head of the actuator. A control circuit with a controller signals which piezo-morph beam to connect to the actuator. This multi-piezo-morph-beam piezoelectric multiplexer can be affixed to the electrical terminals of different electrical components (e.g., a transistor) to create an electrical cell that can be manufactured on a semiconductor chip or in a microelectromechanical system (MEMS) device.
