ETH Zurich breath acetone monitoring device
Entities: Andreas Güntner · University Hospital Zurich · Nutrion · ETH Zurich · Alivion
Overview
Researchers at ETH Zurich announced a handheld breath‑acetone analyser, named Nutrion, that quantifies acetone in exhaled air to indicate fat oxidation (ketosis). In a study of twelve healthy adults who provided 312 breath samples under varied conditions, the device measured acetone from 0.2 to 45 ppm in about 90 seconds and showed a 0.995 correlation with laboratory mass‑spectrometry, demonstrating laboratory‑grade accuracy.
A few days later, the team detailed the device’s integration with a smartphone app and its production by ETH spin‑off Alivion. Validation at the University Hospital Zurich confirmed that the analyser’s results matched blood tests and high‑precision instruments. The developers suggest the compact, user‑friendly system could support personal monitoring for obesity, diabetes, epilepsy, diet programs, and athletic training without the need for blood draws.
Both reports underscore the technology’s reliability over months of use and its potential to bring metabolic monitoring into everyday settings.
