Hydrogel‐based sensors with excellent flexibility and stretchability have received extensive attention. However, fabricating anti‐freezing, high‐strength, and conductive hydrogel‐based sensors remains a significant challenge. A stretchable sensor with high strength and anti‐freezing herein is constructed using poly(vinyl alcohol)/urea (PVA/urea) ionic hydrogels. The PVA/urea ionic hydrogels were prepared...
