Abstract

In this paper, we have developed a wearable electronic nose (e-nose) embedded on cloth for detecting the body odor of wearer, aiming to be a self-monitoring healthcare consumer electronics. This "smelling shirt" consists of eight on-fabric chemical gas sensors based on polymer/functionalized-SWCNTs simply fabricated by embroidering and drop coating process. Sew-able electronic modules based on LilyPad Arduino together with wireless ZigBee module were used for data acquisition and communication. The performance of the sensors has been tested by a selected set of volatile organic compounds as presented in the body odor, such as dodecane, 2-ethylhexanol, butyric acid, 6-Methyl-5-heptenone, nonanal and water. Discrimination of individual health status and analysis of the odor-print (or smell-print) of specific persons were confirmed by principal component analysis (PCA), which was found to be able to track change in the human body odor, thereby showing its potential to be applied for real-time point-of-care health monitoring.

用于监测和识别体臭特征的穿戴式电子鼻

在本文中，我们开发了一种嵌入在布料上的可穿戴电子鼻(e-nose)，用于检测佩戴者的体味，旨在成为一种自我监测的医疗保健消费电子产品。这种“气味衬衫”由八个织物上的化学气体传感器组成，这些传感器基于聚合物/功能化swcnts，通过刺绣和滴涂工艺简单制造。采用基于LilyPad Arduino的可缝式电子模块和无线ZigBee模块进行数据采集和通信。传感器的性能通过一组选定的挥发性有机化合物进行测试，如十二烷、2-乙基己醇、丁酸、6-甲基-5-庚烯酮、壬醛和水。主成分分析(PCA)证实了个体健康状况的区分和特定人员的气味指纹(或气味指纹)的分析，发现它能够跟踪人体气味的变化，从而显示其应用于实时护理点健康监测的潜力。
