Triboresistive Touch Sensing In article number 2108586, Jeong-Yun Sun and co-workers report a novel type of touch sensing, termed triboresistive touch sensing, which is developed for self-powered gridless touch recognition. An ionic poly(dimethylsiloxane) exhibiting high transmittance (96.5%), stretchability (539.1%), resilience (99.0%), and ionic conductivity (0.25 mS m−1) is designed to generate power based on the electric field generated by touch. The generated voltages ensure recognition of the touch positions without electrode grid layers and external power sources.
