Constitutive equations of piezoelectricity in real
life environmental conditions are dependent upon change in
temperature, electric field, moisture etc. Piezoelectric
coefficient and dielectric constant of piezoelectric materials
appreciably change with change in DC bias, AC electric field
and temperature. This work discusses variation of piezoelectric
coefficient and dielectric constant with electric field and
temperature. Graphs have been reproduced from literature to
show this variation. Crisp tables showing variation have also
been created for ready use. |
