In article number 1900216, Ting Zhang and co‐workers propose a dual‐signal responsive flexible volatile organic compound sensor based on surface wrinkles with both dynamic visual feedback and a quantitative electrical signal. Tunable sensitivity and selectivity are well‐controlled, and the high selectivity toward ethanol vapor is explained by a proximity mechanism. This platform can provide a novel approach for developing smart flexible electronics.
