Continuous Glucose Monitor
The FreeStyle Navigator, now under FDA review, uses a sensor implanted under the skin to measure the blood glucose of diabetics, without needles, once a minute. At-home disease screening: Place a drop of saliva onto a microchip, and the system will diagnose any of 10 diseases–oral cancer, Alzheimer's, the flu–before you show symptoms. The mirror will make a doctor's appointment to confirm any findings. David Wong, director of the UCLA Dental Research Institute, developed a saliva test for oral cancer and is working on others.
