Pro‐Healing Zwitterionic Skin Sensor Enables Multi‐Indicator Distinction and Continuous Real‐Time Monitoring

In both artificial electronic and ionic skins, the distinction of multi‐stimuli response in a single sensing unit is challenging, due to unavoidable mutual signal interference. Here, a zwitterionic skin sensor system that can continuously monitor and differentiate three‐stimuli‐responsive information in real‐time is designed. This sandwich‐structured sensor system is based on a zwitterionic thermo–glucose‐sensitive skin‐like hydrogel at its...
