Integrity Applications develops the GlucoTrack model DF-F, a noninvasive blood glucose monitor designed to help people with diabetes obtain blood glucose level measurements without pain. GlucoTrack enables individuals with type-1 and type-2 diabetes to measure their blood glucose levels without drawing blood. A small sensor clips comfortably to the earlobe, while the blood glucose level is calculated using a proprietary algorithm. The results are displayed on a handheld device the size of a smartphone. GlucoTrack removes the two most significant barriers to frequent monitoring of blood glucose levels by diabetics: pain (the device is noninvasive) and cost (no disposables are required).
