The piezoelectric effect is understood as the linear electromechanical interaction between the mechanical and the electrical state in crystalline materials with no inversion symmetry.
Fundamental Construction of USM
Ultrasonic motor by barth
Standing Wave USM
U(x ,p)= A cos(k x) cos(wt) + A cos(k x - 90)
Hence the ultrasonic motors, which is a new step in the miniaturized electrical technology has got many applications in small appliances because of its high torque at low density.
