Got diabetes? Do sweat it.

University of Texas at Dallas researchers have developed a new wearable for type 2 Diabetes management, which promises tons more data in exchange for a lot less blood. Instead, their device asks for just 1-3 microliters of sweat, which is probably less than the amount formed on my keyboard in the process of writing this article. The biosensor uses a “room temperature ionic liquid” to stabilize the skin’s environment, ensuring reliable readings of glucose, cortisol, and interleukin-6 compounds for up to a week. So instead of jabbing themselves hundreds of times in a month with single use test strips, diabetics could just buy 4 biosensors and be all set, while having the luxury of pulling up their levels on the device’s app at any time.
