In this paper, the fabrication of aligned semiconducting single-walled carbon nanotube (SWNT) devices on a thermally grown silicon dioxide (SiO₂) over silicon (Si) substrate is presented. The SWNTs are aligned between the nickel fingers that are patterned on the substrate. Subsequently, the fabricated devices are bonded onto a low-cost printed circuit board (PCB) with wire bonder. The mounted sensors have been tested for carbon dioxide (CO₂) gas, acetone, and isopropyl alcohol (IPA) vapor sensing at room temperature. The sensitivity values of 27% for the concentration of 15000 ​ppm of CO₂, 52% for the concentration of 7000 ​ppm of acetone, and 67% for the concentration of 900 ​ppm of IPA have been observed with good response and recovery times. The fabricated sensors show better performance than the already reported sensors.

在本文中，提出了在硅（Si）衬底上热生长的二氧化硅（SiO ₂）上制造对准的半导体单壁碳纳米管（SWNT）器件的方法。将SWNT对准在基板上构图的镍指之间。随后，用引线键合机将制作好的器件粘合到低成本印刷电路板（PCB）上。已安装的传感器已在室温下进行了二氧化碳（CO ₂）气体，丙酮和异丙醇（IPA）蒸汽感测的测试。对于15000 ppm CO ₂浓度，灵敏度值为27％观察到7000 ppm丙酮浓度为52％，IPA 900 ppm浓度为67％，具有良好的响应和恢复时间。制成的传感器显示出比已报告的传感器更好的性能。
