Piezoelectric polymers have attracted attention due to their flexibility and self-powered properties. In our laboratory, we have fabricated poly-L-lactic acid nanofiber membranes using electrospinning and investigated their potential applications as piezoelectric sensors. However, because nanofiber membranes have a structure that differs significantly from conventional homogeneous thin films, a comprehensive evaluation of their material properties is necessary. In this study, we conducted a theoretical investigation into the selection of equivalent circuit models for the analysis of electrochemical impedance measurements of nanofiber membranes.
