Scientists have developed a waterproof wearable patch, which when applied directly to the skin, absorbs sweat and within seconds assesses how much cortisol — stress hormone -- a person is producing.

Clinical tests that measure cortisol, which rises and falls naturally throughout the day, provide an objective gauge of emotional or physical stress and can help doctors tell if a patient's adrenal or pituitary gland is working properly.

While current methods require waiting several days for results from a lab, with the novel patch, a user just needs to sweat enough to glisten, apply the patch and connect it to a device for analysis, giving the results within seconds.

"We are particularly interested in sweat sensing, because it offers non-invasive and continuous monitoring of various biomarkers for a range of physiological conditions," said lead author, Onur Parlak from Stanford University, US.
