This paper presents an enhanced piezoelectricity based sensor for touch and temperature sensing. The sensor is realized over flexible polyimide film, making it suitable for application like e-skin. The sensing material is composed of Polyvinylidene Fluoride-Trifluoroethylene (PVDF-TrFE) and Barium Titanate (BaTiO3) nanoparticles. While, the piezoelectric polymer PVDF-TrFE ensures the flexibilit...

Position and/or force feedback is critical in ensuring precise and safe operation of ionic polymer–metal composite (IPMC) actuators in io/micromanipulation. In this paper the design of an integrated sensory actuator is presented, where polyvinylidene fluoride (PVDF) films re used to provide simultaneous feedback of bending and force outputs of the IPMC actuator. The design adopts differential c...

Recently, intelligent sports monitor devices based on self-powered sensor technology have received widespread attention. Here, we designed a triboelectric nanogenerator poly(vinylidene fluoride-vinyl chloride) PV(DF-A) film and polydimethylsiloxane (PDMS) (PP-TENG) to harvest bio-mechanical energy serve as the basketball training sensor. After experimental testing, electron loss ability of is g...

Piezoactive porous polyvinylidene fluoride films prepared in the process based on melt extrusion with subsequent isometric annealing, uniaxial extension and thermal fixation have been studied. It was shown that two competing orientation processes -polymorphous transition of non-polar α-phase into polar piezoactive β-phase formation structure - occur during annealed films. has established degree...

In this work, a comprehensive study of the effect graphite and bronze particles on structure thermal conductivity polyvinylidene fluoride (PVDF) was carried out. Based experiments out, it found that at limit relatively small concentration bronze, melting point PVDF exceeds, confirmed by an increase in longitudinal dimensions crystallites. With amounts fillers contained polymer composite materia...
