From the point of exhaustion athletes warn biosensor tattoos




People are actively involved in sports probably more than once faced with a situation where after the next exercise, the muscles become cotton and their body is literally ceased to obey them. So high technology to the rescue and allow early warning of such situations. For a person not worked himself to exhaustion, at the University of California have created a special temporary biometric tattoo , which will report to the owner about when did he should stop and rest.

A bit of theory. Lack of energy during intense physical exertion occur because the muscles begin to accumulate lactate (lactic acid). When the level is very high, there comes a very rapid fatigue. However, thanks to the timely monitoring, athletes can quickly back in operation without bringing the level of lactic acid in their body to a critical point. Unfortunately, the most effective way of monitoring is currently the only blood test or the use of very bulky and uncomfortable equipment. Agree, for an operating rage (or rhythm) to follow such methods for lactate levels are very uncomfortable.

Professor Joseph Wang of the University of California at San Diego proposes to use an alternative – a flexible electrochemical biosensor, which he himself invented. Attached to the skin, it measures the level of lactic acid in the body when an athlete starts to sweat. The experiments of this ” tattoo “on volunteers, who were engaged on a stationary bike, very accurately showed lactate levels in their body.

Professor Wang hopes that this technology is suitable not only for use during exercise and determine the physical limits of the athletes, but is useful to the soldiers and others who by their activities daily experience exhausting exercise.
