The detection of volatile organic compounds (VOCs) is critical in various applications, e.g., medical care, environmental monitoring, public security, agriculture, the food industry, etc., requiring high sensitivity, good selectivity, fast response/recovery, multivariate data treatment, anti‐interferon, and wide tolerance of gas temperature. Herein, taking advantage of the interface inside the composite thin film of contact electrification‐based sensors, a “fill two needs with one deed” strategy is successfully demonstrated and developed to selectively detect VOCs without a power source, which may shed a new light on VOCs' sensing in the future sensor network.

Abstract
The detection of volatile organic compounds (VOCs) is critical in various applications, e.g., medical care, environmental monitoring, public security, agriculture, the food industry, etc., requiring high sensitivity, good selectivity, fast response/recovery, multivariate data treatment, anti‐interferon, and wide tolerance of gas temperature. Herein, taking advantage of the interface inside the composite thin film of contact electrification‐based sensors, a “fill two needs with one deed” strategy is successfully demonstrated and developed to selectively detect VOCs without a power source, which may shed a new light on VOCs' sensing in the future sensor network.
