Transparent and Mechanically Robust Single‐Network Hydrogels Enabled by Anionic‐Regulated Supramolecular Cross‐linking for Low‐Temperature Human‐Machine Interfaces
Hydrogel sensors are considered to be one of the promising electronic systems for human‐machine interfaces, but high transparency at the expense of mechanical performance has offset their advantages, which significantly limits their practical applications. Herein, we present one type of single‐network hydrogel cons...
