Piezoelectric Effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress. Also, it can be defined as the conversion of electrical energy to mechanical energy. The inverse piezoelectric effect refers to a deformation of the materials that results from the application of an electric field.
Ultrasound is produced and detected using an ultrasound transducer. Which are capable of sending an ultrasound and then the same transducer can detect the sound and convert it to an electrical signal to be diagnosed. To produce an ultrasound, a piezoelectric crystal has an alternating current applied across it. The piezoelectric crystal grows and shrinks depending on the voltage run through it.
