Hundred-Nanometer-Thick Stretchable Liquid Metal Films for Ultra-Conformal Bioelectrodes.

ABSTRACT: Epidermal electrodes have demonstrated promising potential for high-fidelity electrophysiological monitoring owing to their superior conformability. However, achieving conductive films that simultaneously possess ultrathin architectures and high conductivity to enable super conformal skin integration and enhanced signal-to-noise ratios under dynamic conditions remains a formidable challenge. Here, a ≈200 nm-thick liquid metal (LM) conductive film and fabricate an epidermal bioelectrode is reported with a total thickness of merely 1.1 µm. The key innovation lies in a thermal-low temperature synergistic deposition strategy that combines in situ substrate precooling with thermal evaporation, which fundamentally differs from conventional LM film techniques (e.g., printing or sputtering) by ena
