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.
