Effect of Phase Change in Piezoelectric Ceramic-Polymer Composites and their Applicationspdf Gowdhaman P INTRODUCTIONDevelopment and investigation of smart materials become the centre of attraction among the most of the researchers around the globe due to its wide range of applications. Numerous classes of piezoelectric polymers such as polyvinylidene fluoride polylactic acid cellulose polyamides polyurea polyurethanes and their composites used for energy harvesting applications as a productive alternative of leadbased piezoceramics are extensively addressed and explored. It is produced in large thin clear sheets which are then stretched and poled to give it the piezoelectric properties.

There are mono and polycrystals piezoceramics polymers and composites in the group of piezoelectric materials. Piezoelectric polymer PVDF is a very good candidate for biomedical and for acoustic sensors due to unique properties such as lightweight flexible and one more important property is acoustic. These organic materials thus have an interesting place in applications such as transducers for example in comparison with a piezoelectric ceramic the lead zirconate titanate PZT which is also widely used.

PVDF is chains of CH2CF2 and is a semi crystalline polymer. For implantable applications polymer-based piezoelectric devices are commonly used because of their mechanical flexibility. Piezoelectric polymers can be classified by bulk polymers voided charged polymers piezoelectrets and polymer composites.
