Direct-Ink Writing Processing of High-k Poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene) and Its Integration into an All-Printed Capacitive Touch-Sensing Device
Source abstract
Abstract
Direct-ink writing (DIW) printing technology represents a suitable and efficient additive manufacturing technique for producing intricate designs and structures directly on the application surface. This work has demonstrated the potential of combining DIW and screen printing to fabricate an all-printed 7 × 7 capacitive touch sensor based on high dielectric constant (high- k ) poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene)─P(VDF-TrFE-CFE). The printed device allows a maximum detection signal-to-noise ratio (SNR) of 20 dB, a large touch sensitivity that demonstrates the touch sensor’s ability to detect and respond precisely to user input. Furthermore, by demonstrating the processability of P(VDF-TrFE-CFE) with DIW printing, this research also opens the way for the low-cost fabrication and integration of sensing devices based on this high dielectric constant polymer.
