Accurate extraction of physiological and physical signals from human skin is crucial for health monitoring, disease prevention, and treatment. This research presents ultra-conformal, customizable, and deformable drawn-on-skin electronics, robust to motion due to strong adhesion and ultra-conformality. Electronic inks are drawn directly onto the skin to create devices such as transistors, strain sensors, temperature sensors, heaters, skin hydration sensors, and electrophysiological sensors. The study demonstrates the electronics' immunity to motion artifacts during electrophysiological signal monitoring and shows accelerated skin wound healing using electrical stimulation.
