Research on the Piezoelectric Touch Panel Based on PVDF

With the development of information and automation technology, the touch panel integrated with the display device, which is more intuitive at human-computer interaction, is constantly in-depth people's daily lives. Piezoelectric touch screen is based on the piezoelectric effect of the piezoelectric materials. It has many advantages relative to traditional capacitive, resistive touch screen and so on. In this paper, a new kind of PVDF-based piezoelectric touch panel is put forward originally and fabricated. The basic functions of the touch panel were achieved by the entire piezoelectric touch screen system design and production as well as external test environment. The accuracy of the piezoelectric touch panel can reach 0.5 mm. For the 50 mmx50 mm panel, the resolution is 100 x 100, which can meet the demands of the human-computer interaction.
