The Swiss medical device company, Solianis, is developing products for physiological glucose monitoring, including a non-invasive, continuous glucose monitoring device. Based on impedance spectroscopy, their device uses radio waves and changes in skin resistance to monitor changes in blood composition. Solianis employs a multi-sensor approach to monitor various factors, including body temperature, microcirculation, sweat, moisture in the skin and the thickness of different skin layers as often as once a minute.
A list of future blood glucose and continuous monitors.
GlySens Incorporated is a privately held corporation located in San Diego, California that's been around since 1998. Their focus is on an implantable long term continuous glucose monitoring sensor that will help people with diabetes monitor their glucose levels accurately without the usual fingersticks. The system will include 2 parts: the implanted sensor and an external monitor with a display.
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.
