Sweat-absorbing skin patch monitors health during exercise

Scientists develop a sweat-analysing microfluidic device that sticks to the skin during exercise and delivers real-time health information to the wearer.

LONDON (REUTERS) - This skin-like stretchable sensor absorbs sweat as you work out.

It was developed by scientists from Northwestern University alongside other institutions, who call it a "lab on the skin".

The stick-on patch analyses key biomarkers to show how the body is responding to exercise.
