Flexible dielectric films with a high dielectric constant, utilizing P(VDF‐HFP)/salt composites, were manufactured through the solution casting method. In this work, we studied the impacts of three calcium chloride salts—CaCl2, CaCl2·2H2O, and CaCl2·6H2O—on the surface morphology, crystalline phase transformation, mechanical properties, and dielectric responses of the P(VDF‐HFP) copolymer. The detailed...
This study proposes a piezoelectric polyvinylidene fluoride (PVDF) patch for detecting the movement of the biceps brachii muscle. The polyurethane (PU) elastomer was chosen to perform as an artificial muscle. The PVDF patch rigidly glued onto the stretching PU strip could generate the charge linearly with its applied force. The large strain of 1–4 % of the PU at a low driving voltage has led to the...
