Researchers from North Carolina State University have discovered a technique for controlling light with electric fields. “Our method is similar to the technique used to provide the computing capabilities of computers,” says Linyou Cao, an assistant professor of materials science and engineering at NC State and corresponding author of a paper on the work. “In…

Researchers from North Carolina State University have developed a wearable, wireless sensor that can monitor a person’s skin hydration for use in applications that need to detect dehydration before it poses a health problem. The device is lightweight, flexible and stretchable and has already been incorporated into prototype devices that can be worn on the…
