Wearable sweat sensor thanks to battery-free 'water pump' inspired by plants

Plants and trees soak up water in the soil by letting it vaporize through pores in the leaves. Scientists at TU/e have now taken this principle to develop a sweat sensor through which the sweat itself flows at a steady rate and is analyzed. Using laser micro-manufacturing, they made minuscule structures in flexible plastic and integrated a small analytic chip. Their work overcomes an important hurdle towards the development of flexible sweat sensors that can be stuck on the skin.
