Enhanced Electrohydrodynamics for Electrospinning a Highly Sensitive Flexible Fiber-Based Piezoelectric Sensor

We present our work on enhancing electrohydrodynamic processes to fabricate highly uniform polymer nanofibers for flexible piezoelectric sensors. By optimising nozzle geometry in electrospinning, we achieved improved jet stability, reduced voltage requirements, and more consistent micro/nanofiber production. The resulting sensor, made from electrospun PVDF-TrFE fibers, demonstrates high sensitivity and the ability to detect and distinguish impacts from tiny objects like metal beads, water droplets, and oil droplets — showcasing the potential of our enhanced EHD system for next-generation flexible sensing technologies.
