Self-Healing, Self-Adhesive and Stable Organohydrogel-Based Stretchable Oxygen Sensor with High Performance at Room Temperature

[摘要] tsThe organohydrogel-based O2 sensor features full concentration detection range (0-100%), ultralow limit of detection (5.7 ppm), high sensitivity (0.2%/ppm), excellent selectivity, tunable response/recovery speeds, good linearity, and room-temperature operation.The oxygen sensor can work normally under various extreme environmental conditions, such as low (below −18 °C) and high (above 40 °C) temperatures, dry (11.3% RH), and humid (90.5% RH) environments.An electrochemical reaction-based mechanism is proposed to elucidate the oxygen sensing behavior of ion-conducting organohydrogel.
