摘要：

Practical application of wearable gas-sensing devices has been greatlyinhibited by the poorly sensitive and specific recognition of target gases. Rapid chargetransfer caused by rich sensory neurons in the biological olfactory system has inspired theconstruction of a highly sensitive sensor network with abundant defect sites foradsorption. Herein, for thefirst time, we demonstrate anin situformed neuron-mimic gassensor in a single gas-sensing channel, which is derived from lattice deviation of S atomsin Bi2S3nanosheets induced by gold quantum dots. Due to the favorable gas adsorptionand charge transfer properties arising from S vacancies, the fabricated sensor exhibits asignificantly enhanced response value of 5.6-5 ppm NO2, ultrafast response/recoveryperformance (18 and 338 s), and excellent selectivity. Furthermore, real-time visualdetection of target gases has been accomplished by integrating theflexible sensor into awearable device.
