基于谐振型SAW传感器的呼吸检测系统设计
The Design of a Detecting System for Breath Based on SAW Resonator Sensor
摘要
Abstract
The varieties and amount of Volatile Organic Compounds (VOCs)in human's breath are relevant to the health state of human body, and it can be used in disease diagnosis. A kind of uncoated surface acoustic wave (SAW) resonator sensor is presented to develop a system,which can detect the VOCs in human's breath. The composition and principle of this system is introduced, and the key parts of the system were tested. Several experiments were carried out to test the feasibility of the system. The preliminary experimental result shows that this system can detect VOCs at×10-9(ppb) level concentrations directly, which demonstrate the potential and prospect for the application of human breath examination.关键词
