Temperature-sensing behavior of poly(vinylidene fluoride-trifluoroethylene) film.

In this work, we present the temperature-sensing responses of poly (vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)], a ferroelectric material. This P(VDF-TrFE) was used to investigate its response within the temperature range of 30 to 60 °C. The impedance and capacitance responses were recorded for different temperature values using an LCR meter at variable frequencies, and the resulting measurements proved the high sensitivity of the proposed device. A comparative study was performed to find the best responsive P(VDF-TrFE) weight-percent solution for different temperature ranges. The sensor responded continuously and linearly with high sensitivity. [ABSTRACT FROM AUTHOR]
