An All-in-One, Bioderived, Air-Permeable, and Sweat-Stable MXene Epidermal Electrode for Muscle Theranostics

), and have low and stable electrode-skin interfacial impedance at a variety of environments, facilitating the long-term reliable monitoring of electrophysiology. Taken together with electrostimulation and electrothermal therapy at the skin surface, MBE can diagnose muscle fatigue and restore muscle function by stimulating blood circulation. In addition, it can also be used for muscle rehabilitation training and prosthesis control via human-computer interaction. Our all-in-one, bioderived, air-permeable, and sweat-stable MXene electrode has a great potential for daily wearable healthcare of muscle fatigue.
