摘要：
We present the results concerning the fabrication and characterization of a piezoelectric transducer based on electrospun polyvinylidene difluoride (PVDF) nanofibers. The deposition process was optimized to obtain aligned nanofibers and to maximize the overall piezoelectric effect. The piezoelectric properties were investigated depositing the material on interdigitated metal electrodes implemented on a thin flexible substrate. In order to generate a suitable mechanical stimulation, the device was coupled to an acoustic actuator and its response was recorded at different vibration frequency and during the interaction with humidity and ethanol.
