Back Cover: A Durable, Flexible, Large‐Area, Flame‐Retardant, Early Fire Warning Sensor with Built‐In Patterned Electrodes (Small Methods 4/2021)

In article number 2001040 by Pingan Song, Yan Zhao, and co-workers, a strategy is proposed to fabricate a new type of large-area early fire warning sensor bypatterning fire-sensing, flame-retardant, GO-based coating and conductive ink in an interdigitated way on cotton fabrics. The sensor features a rapid response (<3 s), and is flexible, washable, and mechanically durable, demonstrating its great promise for very early fire warning.
