Acidity, sodium, potassium, calcium, magnesium, creatinine: all these and many other body parameters can be measured in the sweat of our skin. Along with many more in the near future. Interestingly, the measurements will be made directly from the skin by our own clothes.
A group of researchers from the Rovira i Virgili University in Tarragona (Spain) is developing “smart” fabrics impregnated with carbon nanotubes and chemical sensors that are capable of detecting different substances present in sweat. A simple cotton t-shirt can diagnose diseases, capture moods and analyse, at a low cost and on an ongoing basis, the vital parameters of the wearer. These conducting fabrics could be especially useful for athletes and people with chronic diseases such as diabetes.
