An Ultrasensitive and Fast Moisture Sensor Based on Self‐Assembled Dopamine–Melanin Thin Films

Dopamine–melanin thin films self-assembled at the air/solution interface during oxidant-induced dopamine poly­merization are newly evaluated in humidity sensor electrodes, which exhibit excellent performances with response and recover times of ≤3 and ≤7 s, suggesting a promising sensing material for bioelectronics including touchless position interface applications.
