Recently, fairly large numbers of studies have been reported on piezoe
lectric relaxations of polymers. The piezoelectric constants of polyme
r and ferroelectric composites also show such relaxations. It has been
found that both polymer and polymer and ferroelectric composities exh
ibit typical Debye-type piezoelectric dispersion. Cole-Cole diagrams f
or the piezoelectric properties of these materials have been drawn and
an attempt has been made to interpret the results.
