Abstract

We introduce the use of a 55° chamfered nozzle in an electrohydrodynamic (EHD) system to control single-jet mode’s stability and enhance the product’s quality. This nozzle can reduce the critical voltage, broaden stable mode’s voltage range, and promote homogeneity in fabricated fibers. The findings demonstrated in generating highly uniform poly(vinylidene fluoride-cotrifluoroethylene) (PVDF-TrFE) fibers for a flexible piezoelectric sensor. Owing to the fibers’ excellent quality, the sensor shows high sensitivity and ability to detect the drops of a metal bead, or a water droplet from 20 cm height. This shows potential use of modified chamfered nozzle in practical EHD fabrication processes.
