The IDRO sensor measures the lactate (in mMol/l) and the pH values of the sweat. In addition, the temperature in the sampling cell is also measured, which is a good reflection of the temperature of the sweat at the measurement site. The pH and temperature are measured because this gives more insights into the physiological processes inside the body during exercise. There are clear links between lactate in sweat, sweat temperature and sweat pH. With these values, you get your accurate results.

The IDRO system comprises an electronic reader, a sampling cell with microfluidic channels and sensing electrodes. The sensing electrodes are placed onto the microfluidic channels and come into contact with the sweat. The chemical reaction of the electrodes with sweat creates an electrical signal that the electronic reader translates into a lactate value. This value is visualized in real-time in the IDRO app on a smartphone. This allows a real-time display of sweat lactate values in the app. Relevant details or information that you want to share with your visitors. Please read more in this blog post.

The validity of the IDRO sensor has already been scientifically investigated. The sweat measurements of the IDRO device were compared with the gold standard, ion chromatography and we found a good correlation between both measurements (R² = 0,95) with a difference ranging from 2 to 11%.
