Abstract Scope Semi-crystalline polymer, poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] copolymer is a flexible piezoelectric material. Using the electrospinning method and controlling the parameter such as annealing temperature and molecular chain orientation to design smart skin. In this study, we investigated the mechanical and piezoelectric properties of P(VDF-TrFE) by in-situ X-ray diffraction experiment, d33 meter and ferroelectric properties measuring instrument. Hence, to a large extent, the change of the strain response with load observed here can be understood by linking it to the polarization and electric field with strain change. By using the derived relationship between a and b lattice constants, the lattice strain were calculated respectively. Moreover, we find that the b-lattice strain has a similar increasing trend like macro piezoelectric coefficient(d33) upon increasing applied voltage. Our research finding provides evidences that macroscopic properties can be estimated by evaluating its microstructural responses.
