Engineers at the Swiss Federal Institute of Technology Lausanne (EPFL) have created a wearable sensing chip that can measure the concentration of cortisol in sweat. Cortisol is the body’s hormone released when a body is stressed, therefore, the chip could lead to wearables like smartwatches that can monitor its user’s stress levels throughout the day. “Until now there has been no way to quantify stress levels in an objective manner,” EPFL wrote in its announcement. “
“That’s the key advantage and innovative feature of our device. Because it can be worn, scientists can collect quantitative, objective data on certain stress-related diseases. And they can do so in a non-invasive, precise, and instantaneous manner over the full range of cortisol concentrations in human sweat,” Nanolab head Adrian Ionescu said.
The patch developed by the EPFL’s Nanoelectronic Devices Laboratory (Nanolab) and Xsensio has a transistor and an electrode made from graphene. After test running their creation in the lab, the engineers are ready for testing in the hospital. They’re now working with the Lausanne University Hospital to trial the system on human patients.
