Today, I'm going to talk about a special werable because this smart health connected patch analyzes your sweat to detect stress.

This smart health connected patch that analyzes your sweating was developed at Stanford University by a small team of researchers. One document describes it as "a wearable perspiration sensor that measures the elements found in perspiration". Specifically, this extensible patch will measure cortisol.

Cortisol levels can indicate the proper functioning of the pituitary and adrenal glands, and also provide information on stress, blood pressure, metabolism, immune response and even memory. In short, a lot of information that you need for a sport; or to detect diseases.

The sensor takes the form of a patch that sticks to the body. The idea is that the person gets enough exercise to "sweat enough" and then apply the patch. The membrane will let the salt found in the sweat, but blocks, collects and measures the cortisol. "We are particularly interested in sweat detection because it provides non-invasive and continuous monitoring of various biomarkers for a range of physiological conditions," said Onur Parlak, the author of the paper. "This offers a new approach for the early detection of various diseases and the evaluation of sports performance," he continued.

The next challenge for the team is to make the patch reusable. This is not the first time we have seen wearables designed to monitoring perspiration. The University of Pennsylvania used graphene, a material considered "the best existing sensor material," to create GraphWear's SweatSmart.

And companies like LVL and Halo Wearables have also analyzed sweat as a measure of hydration. The Halo Edge analyzes your sweat to indicate hydration levels.
