Technology has revolutionized the field of smart health connected health. There is currently an impressive number of objects that allow self-measurement to always be aware of one's general state of health. Fitness-oriented smart health connected wristbands are certainly among the most complete smart health connected objects, but they could soon be dethroned by less bulky devices, directly glued to the skin, like this patch that analyzes sweat.

After Techno tattoos, Tech Tats, which are still in the prototype stage, US researchers have come up with a patch that allows to know more about the physiological health of athletes by analyzing the chemical compounds contained in sweat. Eventually, this patch can be used to establish a diagnosis in replacing the blood tests.

A mini-laboratory contained in a patch

This patch could become in the future the ultimate solution for athletes who wish to follow live the effects of their physical efforts on their metabolism. By knowing more about the functioning of their body during their exercise sessions, such a device will allow them to further optimize their performance.

Once stuck on the skin, this patch or epidermal patch, designed by a team of American researchers, records the chemical compounds of sweatsuch as the pH as well as the concentration of glucose, chloride and lactate. This information is sent to an application in a smartphone and provide information on the state of health of the wearer.

Scientists are currently only in the Review phases. The patch was used with cyclists to avoid dehydration. It is composed of 4 mini tanks, which change colors according to the composition of the athlete's sweat. He then knows precisely when it is time to hydrate. BSX Athletics and its LVL bracelet offers similar functionality. In the future, the patch can become a real diagnostic tool. " The sweat analysis platform we developed will allow people to monitoring their health on the spot, without the need for a blood sample; integrated electronics do not require a battery and allows a wireless connection to a smartphone Said Yonggang Huang, a researcher who participated in the project.

The first tests are conclusive

About twenty cyclists took part in tests to evaluate the accuracy of the measurements made with the patch and the results are promising. The athletes were separated into two groups, one having participated in an outdoor race and the other having practiced their sport on machines in a gym. It turns out that in both cases the results obtained with the patch are similar to those obtained with advanced machines..

This patch, disposable, also requires no source of energy. The researchers hope that their invention will be commercialized within 3 years.
