A patch could revolutionize the way we monitor stress.
An investigation focuses on the development of an interesting device. It is an electrochemical patch that effectively measures the levels of the hormone responsible for stress: cortisol.
According to scientists, these are bands similar to what is called the "patch bandaid". Its form of use is quite simple: just apply it to the skin to absorb a little sweat and deliver results.
Onur Parlak, a postdoctoral researcher at the Salleo Laboratory and lead author of the research, discusses development In a statement from Stanford University:
We are particularly interested in the detection of sweat. It provides non-invasive and continuous monitoring of multiple biomarkers for a variety of physiological conditions (…) This provides a new approach for the early detection of various diseases and the badessment of sports performance.
The following image represents the layers contained in the cortisol biosensor, which was developed by the Salleo laboratory, and two images of the holes in the bottom of the sensor that absorb sweat:
