Ferroelectricity:
Ferroelectricity is a feature of certain materials with automatic electrical separation that can be altered by the use of an external electric field. All ferroelectric are pyroelectric, with additional properties where their separation of the electrical environment can be reversed.
Piezoelectricity:
Piezoelectricity is the electrical charge that accumulates in certain solids - such as certain ceramics, crystals, and living organisms such as bone, various proteins, and DNA in response to mechanical stress applied. The term piezoelectricity refers to the electricity generated by subtle pressure and heat.
