Structural Engineering of Reversible Hydrogel Nanocomposites for Dehydration‐Free and Highly Durable Wearable Sensing Arrays
Hydrogels consist of crosslinked polymer chains that can hold substantial water within their 3D architectures. Nevertheless, most of this water exists in an unbound state, rendering progressive dehydration an inherent limitation that undermines fracture toughness and long‐term fatigue durability. Although PVA/glycerol...
