Dry electrodes offer a promising solution for precise physiological signal recording without invasiveness of gel-based electrodes, which suffer from issues like declining conductivity over time and poor adhesion to moist skin. However, balancing conductivity and flexibility in dry electrode has been a significant challenge. This study addressed this issue by blending organic conductive polymers with inorganic metal nanoflakes to develop stretchable, conductive, and elastic dry electrodes. By optimizing the material composition, researchers achieved electrodes that withstand significant deformation while maintaining stable resistance under strain. Notably, these electrodes exhibited minimal resistance variations of just 1.13 % even after 1,000 stretching cycles at 100% strain. Additionally, these electrodes consistently provided clear monitoring of physiological signals, such as ECG and EOG, with a high signal-to-noise ratio.
