Abstract Triboelectric nanogenerators (TENGs) represent an effective approach for transforming mechanical energy into electrical power, making them suitable wearable electronic applications. Hydrogels as TENGs electrodes are common, but their use direct triboelectric layers remains insufficiently explored. Here, a novel zwitterionic monomer 3‐{1‐[6‐(hydroxymethyl)‐2‐methyl‐3,8‐dioxo‐9‐aza‐4,7‐dioxadodec‐1‐en‐12‐yl]imidazol‐3‐ium‐3‐yl}propane‐1‐sulfonate (VNIPS) is synthesized in combination with acrylic acid (AA) and sulfobetaine methacrylate (SBMA) to create double‐network hydrogel. The hydrogel developed using solvent‐exchange process that facilitated the creation of microphase‐separated domains, notablely increasing its strength (211.9 kPa, 472.3%), conductivity (0.6 mS cm −1 ), anti‐freezing capability (−18.3 °C). In addition, hydrogel's hydrophilic groups interacted water molecules, reducing charge loss humid conditions. When employed positive layer, hydrogel‐based achieved substantial density 456 µC m − 2 output power 464 mW , while maintaining steady open‐circuit voltage (V oc ) 97 V, 92% retention under 80% relative humidity. Moreover, strong adhesion biocompatibility make it applications, such motion sensing Morse code communication. This work demonstrates feasibility hydrogels materials, providing new strategy creating efficient, humidity‐resistant harvesters.
