UPDATE #1: Recent improved performance of this device can be attributed to a new shell design and a proprietary filling material for their quality control device called the phantom finger. A new algorithm development process is being tested for effectiveness in the transfer of algorithms to other instruments. This update comes from the Chief Scientific Officer, Thomas G. Scecina

This small R&D company, based in Dortmund, Germany, claims it is close to production of what is believed to be a near IR device, although it's operational range of 80% humidity or less may indicate a middle IR device. It has been developed in conjunction with a Korean company, Samsung Fine Chemicals Co., Ltd. Called the GluControl® GC300 and measuring 17.6 x 11.6 x 6 cm, with a weight of 500 grams (18 oz.), it is designed for home use.
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.
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.
