摘      要：Surface electromyography(sEMG)sensors play a critical role in diagnosing muscle conditions and enabling prosthetic device control,especially for lower extremity robotic ***,challenges arise when utilizing such sensors on residual limbs within a silicon liner worn by amputees,where dynamic pressure,narrow space,and perspiration can negatively affect sensor *** commercial sEMG sensors and newly developed sensors are unsuitable due to size and thickness,or susceptible to damage in this *** this paper,our sEMG sensors are tailored for amputees wearing sockets,prioritizing breathability,durability,and reliable recording *** employing porous PDMS and Silbione substrates,our design achieves exceptional permeability and adhesive *** serpentine electrode pattern and design are optimized to improve stretchability,durability,and effective contact area,resulting in a higher signal-to-noise ratio(SNR)than conventional ***,our proposed sensors wirelessly enable to control of a robotic leg for amputees,demonstrating its practical feasibility and expecting to drive forward neuro-prosthetic control in the clinical research field near future.
