Piezoelectric polymers are polymers that can generate electric charges on the surface under pressure/strain and thus convert mechanical energy into electrical energy.
Stretched and polarized polyvinylidene fluoride (PVDF) is one of the representative piezoelectric polymers commonly used.
In practice, piezoelectric polymers are classified based on the topology and dipole moment. They are divided into bulk polymers, polymer composites, and voided charged polymers.
