Sobriety test, which commonly uses a breathalyser for estimating blood alcohol content (BAC) from a breath sample, is commonly used to detect drunk driving. The detection often gives rise to sanitary concern and violation of human right. This research proposes a new method that employs non-invasive measurement of photoplethysmography (PPG) signal for detecting BAC of the test subject under the sobriety test. The PPG signal is measured via an LED transmitter and a receiver that illuminates finger and measures the changes in lighting. Since a PPG signal contains information of systolic and diastolic blood pressure, it is possible to be used for the purpose of detecting BAC. The authors have developed a practical alcohol sobriety test system to analyse the status of alcohol intake of the subject. Extensive tests have been conducted to examine feasibility of the proposed system with an identification rate up to 85%.

基于光电容积脉搏波信号的酒精浓度无创检测
清醒测试通常使用呼气测醉器从呼气样本中估计血液酒精含量 (BAC),通常用于检测酒后驾驶。检测往往会引起卫生问题和侵犯人权。本研究提出了一种利用光体积描记(PPG)信号的无创测量来检测清醒测试下受试者的BAC的新方法。PPG 信号通过 LED 发射器和接收器测量,该接收器照亮手指并测量照明的变化。由于PPG信号包含收缩压和舒张压的信息,因此可以用于检测BAC。作者开发了一个实用的酒精清醒测试系统来分析受试者的酒精摄入状况。
