Abstract

UNLABELLED: A novel transparent touch sensor was fabricated with a drop-on-demand inkjet printing technique on borosilicate glass and flexible polyethylene terephthalate (PET) substrates. Conductive poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (

PEDOT: PSS) and dielectric poly(methylsiloxane) were deposited on a desired area to form a capacitive touch sensor structure. The properties of the printed sensors (optical transparency, electrical resistance and touch sensing performance) were investigated with varying

PEDOT: PSS printing passes. A novel transparent touch sensor fabricated with an all-inkjet-printing method is demonstrated for the first time. This process holds industrially viable potential to fabricate transparent touch sensors with an inkjet printing technique on both rigid and flexible substrates for a wide range of applications.
