▎ 摘　　要

NOVELTY - Thin film epidermal electronic device comprises polymer film having one or more holes, where polymer film comprises conductive nanomaterials embedded at or just below surface of polymer film; conductive nanomaterials are connected to form network of nanomaterials, for causing at least portion of polymer film to act as electrode, where polymer film is insoluble in water, and soluble in organic solvent. USE - Thin film epidermal electronic device used for skin-mountable biopotential sensing for healthcare and textile-integrated touch sensing for human-machine interfaces. ADVANTAGE - The thin film epidermal electronic device enables to achieve long-term wearing; develop gas-permeable and ultrathin materials in simple and scalable fashion; has low skin-electrode impedance and high-quality biopotential signals. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a garment, which comprises thin film epidermal electronic device; (2) a method for making thin film epidermal electronic device, which involves: (a) creating polymer layer by adding solution of polymer and organic solvent on substrate; (b) evaporating organic solvent from polymer layer; (c) forming holes in polymer layer by evaporating water droplets, where space occupied by particular water droplet becomes hole after evaporation of particular water droplet; (d) removing polymer layer from substrate; (e) embedding conductive nanomaterials in polymer layer by dip-coating polymer layer in solution comprising conductive nanomaterials; and (f) using heat-press to adhere conductive nanomaterials to polymer layer.
