Metal oxide nanowires are very promising active materials for different applications, especially in the field of gas sensors. Advances in fabrication technologies now allow the preparation of nanowires on flexible substrates, expanding the potential market of the resulting sensors. The critical steps for the large-scale preparation of reliable sensing devices are the elimination of high temperatures processes and the stretchability of the entire final device, including the active material. Direct growth on flexible substrates and post-growth procedures have been successfully used for the preparation of gas sensors. The paper will summarize the procedures used for the preparation of flexible and wearable gas sensors prototypes with an overlook of the challenges and the future perspectives concerning this field.
金属氧化物纳米线是非常有前途的活性材料，可应用于各种领域，尤其是气体传感器领域。制造技术的进步现在使得在柔性衬底上制备纳米线成为可能，从而扩大了相关传感器的潜在市场。大规模制备可靠感测器件的关键步骤是消除高温工艺，并使整个最终器件（包括活性材料）具有可拉伸性。直接在柔性衬底上进行生长和生长后的处理已成功应用于气体传感器的制备。本文将总结用于制备柔性可穿戴气体传感器原型的程序，并概述该领域的挑战和未来展望。
