Abstract

The development of a poly(vinyldifluoride) (PVdF)-based dynamic pressure sensor for low-pressure application is reported. β-phase PVdF film of thickness 10 m is fabricated using the spin coating method with thermally evaporated Al electrodes (200 nm) on both sides of the film. The film is polled and packaged in a poly(dimethyl siloxane) block. The exposed area of the pressure sensor is 500 m in diameter. A signal conditioning circuit is designed to amplify the signal and a NI DAQ card with LabVIEW software is used to acquire the signal on a PC. The dynamic pressure response of the sensor is recorded which shows linearity in detection. Pressure measured by the sensor is in the range of 10-150 kPa.
