摘要：
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. © 2015 WILEY-VCH Verlag GmbH & Co.
