ABSTRACT:
This invention relates to a method of manufacturing pyroelectricity and piezoelectricity elements consisting of a very thin film of polyvinylidene fluoride or a copolymer of polyvinylidene fluoride less than 7 micron thickness which is stretched while in close contact with a laminating resin which has a low adherence to said film so that said film can be stretched very thin as stated above.
