Abstract

An intrinsically soft and stretchable multicolor display and touch interface is reported. Red, green, and blue pixels are formed separately by photopatterning transition-metal-doped ZnS embedded in silicone gels and transfer printing onto an elastomeric dielectric sheet. The device shows stable illumination while being stretched up to 200% area strain or under different deformation modalities. It also introduces capabilities for dynamic colorations and multipoint capacitive touch sensing.

Keywords: AC powder electroluminescence; stretchable capacitive touch sensors; stretchable displays.
