There is growing interest in pressure sensors based on piezoelectric thin films. Most currently used piezoelectric materials are inorganic materials with inflexibility and have limited application on body surfaces. In contrast, poly-L-lactic acid (PLLA), an organic piezoelectric material with flexibility, is expected to replace inorganic piezoelectric materials. Although the d14 direction is generally known as the piezoelectric property of PLLA, it has recently been reported that PLLA nanofibers prepared by the electrospinning method also exhibit piezoelectric properties in the d33 direction. However, its piezoelectric mechanism has not been fully clarified. In this study, piezoelectric nanofiber films were prepared by electrospinning to develop a sensor that can constantly monitor a patient. The influence of electrospinning parameters on the nanofiber diameter and the piezoelectric properties of the nanofiber film were investigated.
