- Abstract
In this report, we present a closed-loop motor control for a cylindrical collector to obtain continuous and uniform polyvinylidene fluoride (PVDF) piezoelectric nanofibers using near-field electrospinning (NFES) to fabricate PVDF fibers with piezoelectric properties. The fibers were applied to make a force sensor packaged in a smart patch. The analysis of the PVDF process includes determination of concentration, viscosity, electrical conductance, and contact angle. The optimal parameters were determined to make continuous PVDF fibers. The fibers were packaged in polydimethylsiloxane (PDMS) with interdigitated electrode (IED) structures. The molds of IED 1 mm thick with a 0.2 to 1 mm pitch were fabricated by electrical discharge machining (EDM). A conductive silver gel was coated on the IED by soft contact lithography. The fibers on the IED were repolarized at temperature of 65 °C and an electrical field of 7 V/μm. This patch was measured with a voltage signal from 42 to 280 mV under beating forces of 0.05 to 0.5 N. In addition, the average voltage was 104 mV when the work temperature was 25 to 100 °C.
