Nature-inspired dual self-catalytic system enabled by urushiol-iron: A green strategy toward tough, conductive, and anti-swelling hydrogels for wearable sensors.
Soft wearable electronics require hydrogels that are mechanically robust, electrically conductive, and easy to fabricate, yet these properties rarely coexist. Here, we solve this dilemma by taking inspiration from natural lacquer, a material used for millennia to create durable coatings. Its key component, urushiol, be...
