The piezoelectric actuators are the device or transducers that use the electrical energy and then convert it into mechanical stress or displacement, and all these things depend on the piezoelectric effects. These are the material used to produce the electric current, which is why they are referred to them as motors.
It can even compressor stretched so that it can generate the electrical output. The piezoelectric material is used in several devices or application that helps in many things.
It helps in generating the force, response speed and even offers energy efficiently. It helps in controlling. It harnesses the motion and helps in providing the short strokes with fast response and high frequency.
