  We describe the phenomenon of generation of an external field of forces from
piezoelectric materials subjected to the application of electric fields or
mechanical stress. The piezoelectric materials are shown as being capable of
producing induction forces in external objects and we conclude that the nature
of the forces generated are not originated from the traditional interactions.
Further we specifically assert that the generation of forces by the
piezoelectric materials is ruled by the hypothesis of preexisting condition of
generalized quantum entanglement between the molecular structure of the
material bulk and the surrounding environment. In addition the widely spread
coupling of the molecules with the environment can be manifested from the
so-called direct effect or the converse effect in piezoelectric materials and
this coupling is not intermediated by acoustic waves or electromagnetic fields.
We show that the novel effect has a theoretical explanation consistent with the
generalized quantum entanglements and the direction of the induced forces
depends on either the direction of the mechanical force or the electric field
applied in these materials.
