Piezoelectricity

The piezoelectric effect is described by a rank 3 tensor which relates stress with the electrostatic polarization.

(a) Write down the tensor equations for the piezoelectric effect and for the inverse piezoelectric effect.

(b) Explain how you would determine the independent components of the piezoelectric tensor for the tetragonal point group 4.
