提出并测试了一种基于多壁碳纳米管（MWNTs）的新型微加工呼吸传感器（MBS）。它有一个简单的结构，两个镍梁结合多壁碳纳米管。MBS对呼吸动态特性的行为的响应与人类志愿者的呼气脉冲（例如，呼气流强度和频率）一致。它在检测微弱呼吸时具有快速响应和高灵敏度，并且没有检测到诸如吸附型传感器的恢复问题。此外，还观察到较强的抗干扰能力，外部空气流动和温度漂移。这些独特的结果确保了该MBS可以成功地用于人体呼吸的实时监测。(C)2010 Elsevier B.V.保留所有权利。
A novel microfabricated breath sensor (MBS) based on multi-walled carbon nanotubes (MWNTs) has been presented and tested. It has a simple structure of two nickel beams incorporating with MWNTs. The responses of the MBS to the behavior of the breath dynamic characteristics are consistent with the exhalation pulse of the human-volunteers, e.g. the exhale flow strength and frequency. It has a rapid response and high sensitivity in detecting feeble breath, and no recovery issues such as the adsorption-type sensors are detected. Furthermore, strong anti-interference ability to external air flow and temperature shift is observed. These unique results ensure this MBS can be successfully employed to real-time monitoring of human breath. (C) 2010 Elsevier B.V. All rights reserved.
