When subjected to an electric field applied across its thickness, the piezo ceramic layer expands or contracts due to the converse piezoelectric effect. The passive layer constrains this motion, causing the unimorph to bend concavely or convexly. This bending displacement can be harnessed in sensing or actuation applications. Unimorphs exhibit much larger bending deformations compared to traditional piezo stack actuators.
