Modeling and Experimental Characterization of Flexible Touch Sensor Panels

For the first time, we present a comprehensive framework for the analysis and design of deformable capacitive touch sensor panels. A fast quasielectrostatic simulation is used to build equivalent circuit models of touch sensor panels under bending and stretching. We validate these models with a set...

description For the first time, we present a comprehensive framework for the analysis and design of deformable capacitive touch sensor panels. A fast quasielectrostatic simulation is used to build equivalent circuit models of touch sensor panels under bending and stretching. We validate these models with a set of measurements performed on a polymide touch sensor. Leveraging this modeling capability, we propose an electrode pattern that is promising for fully deformable touch sensor panels.
