A researcher team from Purdue University, Indiana have developed a smartphone device and an app that together quantitatively analyzes and store the results of strip-based saliva alcohol tests—which is helpful, since the current method consists of matching up the strip against a color scale on its packaging. The dipsticks used are sensitive to the saliva alcohol range of 0.02% to 0.30%, which is sufficient to determine if someone should be operating a motor vehicle. Additionally, the app allows for storage and recall of this data.
