Wearable Hydration Sensor (IMAGE) North Carolina State University Caption Researchers from North Carolina State University have developed a wearable, wireless sensor that can monitor a person's skin hydration 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 wrist or as a chest patch (as seen here).
