Novel sweat sensor may spell end for painful needle pricks

Scientists are developing wearable skin sensors to analyse sweat, which may help bypass the need for more invasive procedures like blood draws, and provide real-time updates on health problems such as dehydration or fatigue.The sensor design, described in the journal Science Advances, can be rapidly manufactured using a “roll-to-roll” processing technique that essentially prints the
