Ultrahigh-transparency and pressure-sensitive iontronic device for tactile intelligence

Abstract Emerging tactile sensing devices mimic biological functions of human mechanoreception. By introducing the feature optical transparency, it can lead to a combined capacities and visual intelligence into single system. Yet, is difficult realize ultrahigh level transparency device sensitivity in structure, for widely used methods improvement, such as elevating interfacial roughness, may further reduce transparency. utilizing transparent ionic material with tunable surface topologies, well strategy refractive index matching, we have proposed iontronic (TIS) based on mechanism, simultaneously offering high (83.9 kPa −1 ), (96.9%), highest reported value literature. Benefiting from its comprehensive performance characteristics, TIS hold enormous potential human-machine interfaces industrial medical applications.
