Abstract:
Piezoelectricity is the ability of certain crystalline materials to develop
an electric charge proportional to externally applied mechanical stress and
vice-versa. Nowadays, a large number of piezoelectric sensors and actuator
devices are used in automotive, aerospace, aircraft, medical imaging,
telecommunication and ultrasonic devices2-3. Most of the piezoelectric
ceramics are derived from ferroelectric ceramics by poling at high dc electric
field to introduce anisotropy and piezoelectricity.
