An academic team, led by Dr David Carty, Associate Professor of the Joint Quantum Centre at Durham University, created a device that can detect metabolic imbalances by measuring the levels of acetone expelled in our breath. When fat is metabolised by the body, ketones (including acetone) are produced. The acetone is then expelled from the body in urine, sweat, and also via the lungs as a gas. The aptly named ‘Respiratone’ is a fully integrated, mobile device, that can measure and analyse acetone levels in the breath extremely well, on the go.
