Excessive tattoo

Biological sensor tattoos are designed to prevent excessive exhaustion by measuring lactate levels in sweat secreted.

Any athlete, especially jogging, knows about the situation of 'hitting the wall', the moment when energy falls and it is impossible to continue playing.

This happens when substances called lactates skyrocket in the body, causing fatigue.

Therefore, a group of experts, led by Professor Joseph Wang of the University of California in San Diego (USA), designed an electric bio-chemical sensor, flexible structure, allowing athletes to carry on People like temporary tattoos, according to Gizmag news site.

When applied to the skin, the sensor will continuously measure lactate levels in the sweat produced during exercise.

Test results on volunteers showed that the sensor completed the task well, especially when measuring during exercise.

Methods of measuring lactate levels are currently difficult to perform, blood samples are taken without giving immediate results.

During exercise or competition, when the muscle needs more energy than the body provides, it is lactic acid and lactate produced.

The new sensor can allow the athlete to know when the body is close to the critical level for a corresponding correction.
