This piezo ceramic bi-morph element is a versatile low power electromechanical transducer capable of converting mechanical or acoustic energy to electrical energy. When the element is stressed or subjected to vibration, the minute movement causes one layer to be under tension while the other is under compression. Since the two layers are polarized in opposite directions the opposite stresses in each layer will produce an electrical output. Applications for this device would include vibration / stress sensors, acoustic pick-up sensors and micro-positioners.
