Pneumopipe-sense: Tailoring breath collection and analysis for mobile points-of-care

Pneumopipe is a patented device for breath collection on cartridge. Its evolution towards a portable device for mobile breath analysis in points-of-care or at home, pass through the embedding of the device with sensors for the improvement of the collection process and for a 'preview' breath analysis. Here cyclic voltammetry has been designed and tested, with a specific low-power and low-size electronics, in order to monitor carbon dioxide and oxygen in exhaled breath during collection. The results are promising and the sensors will be integrated in the Pneumopipe, also allowing electrochemical breath analysis in liquids, as already demonstrated in a previous work.
