Two new wearable devices have been developed that use scattered light to monitor biometrics: one tracks glucose and dehydration, and the other monitors pulse. The glucose sensor is the first wearable device that can measure glucose concentration directly but noninvasively. The new pulse monitor is an improvement over current watches in that it will be less sensitive to errors when the wearer is in motion.
