(a) Design strategy for the preparation of PDA-clay-PAM hydrogel. (b) A piece of hydrogel directly adhered to a human arm and a pedometer was attached to the hydrogel, then the pedometer was detached from the arm after a movement and the hydrogel was easily peeled off from the skin without causing any harm or allergies and no residue was observed.
