A new skin patch device has been created for analyzing sweat during exercise. The results collected from the patch are then sent to a smartphone. This information offers a valuable insight into the person’s state of health, for example, whether they require more hydration or whether their electrolyte levels are balanced.
Lead author of the study John Rogers explained, “The intimate skin interface created by this wearable, skin-like … system enables new measurement capabilities not possible with the kinds of absorbent pads and sponges currently used in sweat collection.”
The disposable skin patch is made for one-time use for several hours. It can be placed on the forearm or on the back.
You may be wondering why you should have your sweat analyzed. As Rogers explained, it offers “a rich, chemical broth containing a number of important chemical compounds with physiological health information.”
