In a joint study by EPFL and Xsensio, scientists developed a chip that can measure the amount of cortisol a person secretes from their sweat.

The joint team of Lausanne Federal Institute of Technology (EPFL) and Xsensio has developed a wearable detection chip that can measure the concentration of the stress hormone cortisol in human sweat. The chip provides continuous monitoring, which will help doctors understand and treat stress-related conditions like burnout and obesity.

Significant improvement in early diagnosis of stress-related diseases
Cortisol is usually secreted during the day according to a circadian rhythm (about a day’s change in the physiological and biological processes of the organism), reaching a peak between 6 and 8 am, and then gradually decreasing in the afternoon and evening. If the body produces too much or insufficient cortisol, this can seriously harm an individual’s health and potentially lead to obesity, cardiovascular disease, depression, or burnout.

“This is the most important advantage and innovative feature of our device. Because it can be fitted, scientists can collect quantitative, objective data on certain stress-related diseases,” said Adrian Ionescu, president of EPFL Nanolab, who stated that so far no other system has been developed to continuously monitor cortisol concentrations throughout the circadian rhythm. said.

Esmeralda Megally, CEO of Xsensio: “The joint R&D team at EPFL and Xsensio has reached an important R&D milestone in the detection of cortisol hormone. We look forward to testing this new sensor in a hospital environment and gaining new insights into how our bodies work. “He made the statements.
