A piezoelectric polymeric material in the form of sheet or film, which comprises polymers of vinylidene fluoride (VDF) as principle components. The piezoelectric material is essentially a mixture of 100 parts by weight of a VDF base resin, which may be either poly(VDF) or a copolymer, and 1-100 parts by weight of a copolymer of a fluoroelastomer and either VDF monomer or a monomer mixture containing a major amount of VDF monomer. A sheet or film having a high piezoelectric modulus is obtained by stretching a sheet or film of said mixture at an adequately elevated temperature and polarizing the sheet or film after or during the stretching thereby making the stretching sheet or film an electret.
