A stretchable, transparent, and body‐attachable chemical sensor is assembled from the stretchable nanocomposite network film for ultrasensitive chemical vapor sensing. The stretchable nanocomposite network film is fabricated by in situ preparation of polyaniline/MoS₂ (PANI/MoS₂) nanocomposite in MoS₂ suspension and simultaneously nanocomposite deposition onto prestrain elastomeric polydimethylsiloxane substrate. The assembled stretchable electronic sensor demonstrates ultrasensitive sensing performance as low as 50 ppb, robust sensing stability, and reliable stretchability for high‐performance chemical vapor sensing. The ultrasensitive sensing performance of the stretchable electronic sensors could be ascribed to the synergistic sensing advantages of MoS₂ and PANI, higher specific surface area, the reliable sensing channels of interconnected network, and the effectively exposed sensing materials. It is expected to hold great promise for assembling various flexible stretchable chemical vapor sensors with ultrasensitive sensing performance, superior sensing stability, reliable stretchability, and robust portability to be potentially integrated into wearable electronics for real‐time monitoring of environment safety and human healthcare.

纳米复合网络薄膜的可伸缩电子传感器，用于超灵敏化学气相传感

由可拉伸的纳米复合材料网络薄膜组装而成的可拉伸，透明且可人体附着的化学传感器，用于超灵敏的化学蒸气感测。可拉伸的纳米复合材料网络膜是通过在MoS ₂悬浮液中原位制备聚苯胺/ MoS ₂（PANI / MoS ₂）纳米复合材料并同时将纳米复合材料沉积到预应变弹性体聚二甲基硅氧烷基材上而制成的。组装后的可拉伸电子传感器显示出低至50 ppb的超灵敏感测性能，强大的感测稳定性以及对高性能化学蒸汽感测的可靠拉伸性。可伸缩电子传感器的超灵敏传感性能可以归因于MoS的协同传感优势₂和PANI，更高的比表面积，互连网络的可靠传感通道以及有效暴露的传感材料。有望组装具有超灵敏传感性能，出色的传感稳定性，可靠的可拉伸性和强大的便携性的各种柔性可拉伸化学蒸汽传感器，有望将其集成到可穿戴电子设备中，以实时监控环境安全和人类保健。
