Flexible temperature sensor containing PVDF material. a Schematic of transparent, flexible rGO/P(VDF-TrFE) nanocomposite FET. The schematic illustrates structural, optical (transparent) and electrical (response to temperature) properties of the transparent, flexible R-GO/P(VDF-TrFE) nanocomposite FET [113]. b The structure of physically responsive field-effect transistor (physi-FET) with the bottom-gated and top-contact structure, where the gate dielectric is comprised of nanocomposite of P(VDF-TrFE) and BaTiO3 nanoparticles and the channel is organic semiconductor of pentacene [112]. c Schematic diagram of the ZnO/PVDF composite film and rGO electrodes [110]. d Photograph of the flexible MFSOTE matrixes [23]
