Toshiba has developed a prototype breath analyzer that can detect a wide range of trace gases in exhaled breath. It has the potential to diagnose diseases and monitor health.
For example, the presence of acetone may indicate diabetes, while methane provides clues as to the condition of the intestinal environment.
Toshiba will partner with Waseda University to study the clinical measurements of acetone concentrations in exhaled breath and to correlate the results with fat metabolism, an approach that may advance understanding of how to develop diets and food supplements.
The detectection of other gases, including isotopes of carbon dioxide, will be available in 2015.
