FLOWBIO independently validates its sweat sensor against laboratory gold standard

January 15, 2026

FLOWBIO has published an independent, peer reviewed validation study assessing the performance of its wearable sweat sensor against established laboratory reference methods used in sport science.

London, UK (January 15, 2026) /ENDURANCE SPORTSWIRE/ – FLOWBIO has published an independent, peer reviewed validation study assessing the performance of its wearable sweat sensor against established laboratory reference methods used in sport science.

The study, published in Frontiers in Physiology, evaluates the FLOWBIO Sensor by comparing wearable sweat analysis with laboratory and field standards e.g. Nude body mass for sweat fluid loss, L’Aqua Twin and flame photometry, for sweat sodium measurement. Testing was conducted in controlled dry, hot and humid conditions, across a range of athletes, to assess sweat loss estimation, sweat sodium measurement, and practical application outside the laboratory.

For FLOWBIO, the decision to pursue independent academic validation reflects a clear position. Hydration data should not be assumed, inferred, or internally benchmarked. It should be measured, compared, and published under scientific scrutiny.

The research was led by David Bandiera under the guidance of Yannis Pitsiladis and Sebastien Racinais and Antonio Tessitore, with an international team of sport science researchers including Jean de Bardonnèche, Delphine Margout-Jantac, Léa Dubois, Nisrine El Allaoui, Jonathan Steven Elie Rubio, Jean-Christophe Aubin. The study was conducted through the University of Rome Foro Italico at the CREPS Montpellier, with support from Human Telemetrics.

The paper details how FLOWBIO performs when evaluated against laboratory and field analysis during indoor cycling exercise in hot and dry and hot and humid conditions. By publishing these results, FLOWBIO places its technology within the context of established scientific methods, rather than positioning it outside them.

“Trust in wearable technology should be science driven and only through science can it make the difference” Dr Roel Mingels – Head of Research & Development at FLOWBIO.

Hydration is one of the pillars of endurance performance, influencing physiological strain, recovery, and heat tolerance. As wearable technology increasingly informs training and racing decisions, FLOWBIO’s position is clear.

About FLOWBIO

FLOWBIO is the company behind the world’s most accurate sweat sensor, independently validated to deliver lab precision in real world training and racing. Built for endurance athletes who want to move beyond guesswork, FLOWBIO helps athletes understand how much fluid and sodium they lose when they sweat, and what that means for performance.

The FLOWBIO Sensor is worn during training and racing to analyse sweat in real time. It measures sweat rate and sweat sodium concentration, syncing with the FLOWBIO App to turn raw data into clear, personalised hydration recommendations. Athletes can see how their hydration needs change with effort, intensity, and environmental conditions, and plan accordingly.

At the core of the system is AHi®, FLOWBIO’s proprietary Advanced Hydration Intelligence. AHi® takes sweat data, combines it with effort and environment, and turns it into personalised hydration insights so athletes know what to drink, when to drink, and why.

FLOWBIO is used by endurance athletes across cycling, running, and triathlon who want to stay stronger for longer, recover faster, and adapt better to heat. By turning sweat into performance data, FLOWBIO enables smarter hydration decisions, session after session.
