We present a MEMS sensor for continuous glucose monitoring for diabetes management. The device consists of a microcantilever, which is driven by remote magnetic field and situated in a microchamber separated from the sensing environment by a semi-permeable membrane. As glucose concentration varies, viscosity changes induced by glucose/copolymer binding in a poly(acrylamide-ran-3-acrylamidophenylboronic...
Continuous glucose monitoring has been shown to help diabetes mellitus patients stabilize their glucose levels, leading to improved patient health. One promising technique for monitoring blood glucose concentration is to use optical absorption spectroscopy. This letter proposes the use of thermally tunable 2.3-mum vertical-cavity surface-emitting lasers to obtain blood absorption spectra. The partial...
Optical measurement techniques were continuously applied for glucose sensing for several years. Optical polarimetry is an effect method for the measurement of glucose concentration. In this paper, we introduce a new optical polarimetry probe system which has a variable optical path length.
Measurements of impedance spectra used for non-invasive glucose monitoring are affected by a variety of perturbing factors such as temperature and sweat/moisture fluctuations, changes in perfusion, and body movements. In order to quantify and compensate for these perturbing effects, a multi-sensor approach was suggested. Different sensors are used, measuring signals correlated with blood glucose and...
