The eNose Company is a medical-technical company that has developed the Aeonose, which is able to ‘smell’ diseases quickly and effectvely using sensor technology. The Aeonose uses metal oxide sensors, comparable to sensors in the car industry that detect exhaust gas. The device smells, based on substances in the exhaled air, whether the patient has a disease. Exhaled air contains a large number (>1,500) of different volatile organic compounds (VOCs). These create a representation (breath profile) of the human body’s metabolism. Such a breath profile consists of a lot of data, and is analysed in order to recognise patterns. By analysing many breath patterns, you can ‘train’ an algorithm, and can run an unknown breath profile through it. It will then immediately provide you with a diagnosis.
