Electromechanical coupling factors of the high energy electron irradiated poly(vinylidene fluoride-trifluoroethylene)(P(VDF-TrFE)) copolymer are characterized at the quasi-static (1Hz) and high frequency resonance states. It is found that the transverse electromechanical coupling factor k31 of this material can reach more than 0.45. Furthermore, the result obtained from the resonance method is comparable to that from the quasi-static method.
