Electric dipole moment induced we can examine how induced polarization behaves as a function of an applied electric field, ( , by considering the induced electric dipole moment (cf. The strength of the induced electric field produced by a piezoelectric material in response to an applied physical stress is the product of the value for the applied stress and the value for gij. The potential energy of the dipole is given by ue = − pe cos θ, or in vector notation ue = − p · e.

What kind of electric field do they produce? The induced dipole moment is then the product of the polarizability and the electric field. The dipole moment of an array of charges,
determines the degree of polarity of the array, but for a neutral array it is simply a vector property of the array with no information about the array's absolute location.
