Stretchable Full‐Color Phosphorescent PVA‐Based Ionogels for Multimodal Sensing‐Visual Integration Applications

), and ultralong afterglow lifetime (112.4 ms). This strategy is applicable to chromophores with color-tunable phosphorescence. By leveraging observable full-color RTP and real-time electrical signals in response to diverse stimuli (i.e., stretching and pressing), an intelligent grasping strategy is developed for robust hand pose reconstruction. In addition, a tactile-visual fusion recognition keyboard is created with dual functionality of information encryption and signal transmission. The ease of fabrication, wide tunability, and multifunctionality will help expand the scope of ionogels for smart devices.
