Humans have a uniquely high density of sweat glands embedded in their skin—10 times the density of chimpanzees and macaques. Now, researchers at Penn Medicine have discovered how this distinctive, hyper-cooling trait evolved in the human genome.
No more worries for diabetics with weak muscles. The Metallurgy and Materials Science Research Institute, Chulalongkorn University will soon launch a cutting-edge, health innovation – a wristwatch that can check blood sugar levels from sweat in real-time. It’s accurate, not painful, less expensive, and can replace imported equipment. It is expected to be available on the market soon.
Researchers at North Carolina State University have constructed a paper-based device as a model of wearables that can collect, transport and analyze sweat in next-generation wearable technology. Using a process known as capillary action, akin to water transport in plants, the device uses evaporation to wick fluid that mimics the features of human sweat to a sensor for up to 10 days or longer. They discuss their work in the journal Biomicrofluidics.
Jan Halámek and his team of researchers at the University at Albany, led by Department of Chemistry graduate student Mindy Hair, are developing a sensing strip that can detect a person’s blood alcohol content (BAC) based on ethanol levels in a small sweat sample.
