Detection of high sensitive acoustic region for sensible applications of electrospinning based PVDF-TrFE nanofiber sensor

Abstract Cardinal amount of assessment has been vested on using Polyvinylidene Fluoride-co-Trifluoroethylene (PVDF-TrFE) electrospinning based nanofibers for subtle applications as acoustic sensor. In the current course of experiment, utilizing electron, proton and ionic conductive properties of the PVDF-TrFE co-polymers in conjunction with aluminum (Al) and copper (Cu) as electrodes, demonstrates strong acoustic to electric conversion ability within the audible frequency range of 30 Hz to 15 KHz and fortuitously, sensitive acoustic region has been commended for intricate medical applications. Furthermore, enhanced sensitivity was observed due to advance charge polarization by using Polydimethylsiloxane (PDMS) wrapped on the fabricated device. The standard β -Phasic Perovskite polymer sensor with a sensing congregation can relay convergent sound directly to the nanofiber layer and the resultant sensitivity shows as high as 11 VPa −1 at 40 Hz to 60 Hz incident frequency of normal conversation, which can be efficacious for developing high-performance acoustic based biomedical sensors.
