摘　　要：利用转移技术把真空过滤技术获得分布均匀、层叠分布的碳纳米管薄膜有效地转移到高分子材料基底上,使所获得的碳纳米管复合材料可用于呼吸测量,根据热电效应可通过测量电流的大小和变化获得呼吸强度和频率的数据,统计结果显示,男性呼吸频率低于女性,呼吸强度高于女性。The uniform and layered distribution carbon nanotube （CNT） films fabricated by vacuum filtration process were transferred on polymer basement.The CNT/polymer composite can be used in breath analysis.Due to thermoelectric effects, the strength and frequency of breath can be obtained by detecting the intensity and change of measure current.The frequency and strength of male are 16.4 times/min and 1.122 uA, respectively.The frequency and strength of female are 18.5 times/min and 0.904 uA, respectively.The results shows that the frequency of male is lower than female, and the strength of male is higher than female.
