SpectRx, Inc. is developing a non-invasive test to screen for diabetes by measuring the intensity of fluorescence and scattering in the lens of the eye. Eye measurements are performed through an undilated pupil with the assistance of a pupil tracking system.

Current insulin pens are more convenient than injections with syringes, but they could do so much more. They could be designed like today's smart insulin pumps, and could even be designed to be far more intelligent so they really improve control.
Blue skying means sitting around with friends and sharing what-if ideas. Maybe it's a way to cure diabetes, or to make scattered blood sugar results mean something, or to prevent or treat retinopathy, or a software program that could help deal with diabetes. Whatever it is, this is the place to share it.
The Dexcom STS and the Paradigm RT continuous monitors are currently available in the U.S. with a prescription. In this study, they are compared head to head while being worn by one person with Type 1 diabetes. Over 33 days, 262 simultaneous readings were compared between a One Touch meter and the two continuous monitors. The meter was used to calibrate both monitors and as the standard against which their accuracy was evaluated.
With every new step in diabetes technology, there seems to be a new piece of equipment to carry around. Carrying an insulin pump, glucose meter, and a continuous monitor or logbook along with your cell phone, wallet, and other daily use items can be a little cumbersome. Thanks to HealthPia, you can combine two diabetes tools into one, the GlucoPhone, an all-in-one product that combines a cell phone with a blood glucose monitor. The convenience of this device makes it easier to monitor blood sugars.
Glucose sensing through the use of radio waves is indirect, relying on predictable alterations in how ionic solutes like sodium respond to alternating electromagnetic fields in the presence of glucose. The normal interference in specific radio frequencies caused by sodium are impeded by surrounding glucose molecules. Glucose is not directly affected by longer wavelength radio and microwave frequencies, so it's presence cannot be directly measured.
IR technology has been the most active area in non-invasive monitoring research. A lot of excitement was generated by this technology many years ago when it was found IR waves could directly measure glucose.
Devices were developed that could measure the ripeness of fruit indicated by the glucose content in their skins by reflecting infrared waves off the fruit. Approaches to measure glucose in the body are now being attempted using both near and middle infrared waves are being utilized. IR waves have shorter wavelengths and are closer to visible light than radio waves.
