Comfort and mechanical stability are vital for epidermal electronics in daily use. In situ deposition of circuitry without the protection of substrates or encapsulation can produce imperceptible, conformal, and permeable epidermal electronics. However, they are easily destroyed by daily wear because the binding force between deposited materials and skin is usually weak. Here, we in situ deposited skin-adhesive liquid metal particles (ALMP) to fabricate epidermal electronics with robust wear resistance. It represents the most wear-resistant in situ deposited epidermal electronic materials. It can withstand 1600 cm, 175 g loaded paper tape wearing by a standard abrasion wear tester. Stretchability, conformality, permeability, and thinness of the ALMP coating provide an imperceptible and comfortable wearing experience. Without degradation of electrical property caused by solvent evaporation, the dry ALMP coating possesses natural advantages over gel electrodes. In situ deposited ALMP is an ideal material for fabricating comfortable epidermal electronics.
