Ferroelectric polarization can have an important role to increase output power of energy harvesters by enhancing internal potential. Strong ferroelectric polarization produces high piezoelectric potential and surface potential.

What is the use for ferroelectric materials?

The principal use of ferroelectric ceramics has been in the regions such as dielectric ceramics for capacitor applications (132) ferroelectric thin films for nonvolatile memories, piezoelectric materials for medical ultrasound imaging and actuators, and electro-optic materials for data storage and displays (68).

What is ferroelectricity in chemistry?

Ferroelectricity is a property of certain materials to have a spontaneous polarization which can be reversed by the application of an external electric field. From: Progress in Solid State Chemistry, 2015.
