Chinese Nian Gao Inspired Textured Janus Hydrogel for Body Signal Sensing and Human Machine Interaction.

ABSTRACT: Inspired by Chinese Nian Gao, a traditional food in China, a skin-like bio-hydrogel with asymmetric Janus adhesion and textured structures on its surface is fabricated via a one-pot strategy and is evaluated as electronic skin for sensing and human-machine interaction. The e-skin is constructed through hydrogen bonding and metal-ligand coordination with favorable toughness and stretchability (tensile strength of 173 kPa, strain of 1593%). The bottom surface of the e-skin reached an adhesion strength of 66.7 kPa, and the upper surface shows no adhesion on different substrates, which ensures the stable signal collection on the bottom and avoids interference from incidental contact with clothing or external objects on the upper side. The skin-mimic textures are created in drying, which endows
