This device is aimed at the early detection and monitoring of certain diseases in humans and animals. It analyses the subject's breath upon exhalation (or any gas mixture for that matter). There is a complex nano-VO2 sensor chip in the chamber, the gas source passes through and out via an exhaust. The speed of analysis is pretty remarkable, as the gas will be analysed before it exits the exhaust. In this case, the technology is aimed at the diabetic community, where a measure of the acetone content of their breath is converted to a measure of their blood glucose level. Therefore, this technology represents a non-invasive way for diabetics to monitor their glucose levels as they no longer need to prick their fingers or draw blood.
