Solution-Processed Resistive Pressure Sensors Based on Sandwich Structures Using Silver Nanowires and Conductive Polymer

Highly sensitive resistive pressure sensors are fabricated by a direct spray coating of silver nanowires (AgNWs) on uncured polydimethylsiloxane (PDMS) and an additional coating of a conductive polymer, poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate) (PEDOT:PSS). We have fabricated non-sandwiched sensors (AgNW and AgNW/polymer sensors) and sandwich-structured sensors (sandwiched AgNW and...
