Title:
PIEZOELECTRIC FILM WITH TRANSPARENT ELECTRODE, AND PRESSURE SENSOR
Document Type and Number:
WIPO Patent Application WO/2017/209081
Kind Code:
A1
Abstract:
This piezoelectric film 1 with a transparent electrode is provided with: a piezoelectric film 13 which comprises a laminate of a first base film 11 and a piezoelectric coating layer 12; and a first transparent electrode 14 which is laminated on the piezoelectric coating layer 12. The piezoelectric coating layer 12 contains a fluororesin. The fluororesin is a polymer of vinylidene fluoride or a copolymer of two or more compounds selected from among vinylidene fluoride, trifluoroethylene and chlorotrifluoroethylene. The piezoelectric coating layer 12 is able to be obtained by applying a solution of the fluororesin to the first base film 11 and subsequently drying the solution thereon. A piezoelectric film according to the present invention enables the achievement of a piezoelectric film with a transparent electrode, which has low haze value and high total light transmittance.
