High-fidelity and comfortable recording of electrophysiological (EP) signals with on-the-fly setup is essential for health care human-machine interfaces (HMIs). Microneedle electrodes allow direct access to the epidermis eliminate time-consuming skin preparation. However, existing microneedle lack elasticity reliability required robust interfacing, thereby making long-term, high-quality EP sensing challenging during body movement. Here, we introduce a stretchable adhesive patch (SNAP) providing excellent penetrability electromechanical interface prolonged reliable monitoring under varying conditions. Results demonstrate that SNAP can substantially reduce contact impedance contamination enhance wearing comfort motion, outperforming gel flexible electrodes. Our wireless demonstration exoskeleton robot control shows its potential highly HMIs, even time-dynamic We envision will open new opportunities wearable real-world applications in HMIs.
