Abstract

Design and development of a data acquisition unit for an implantable multi-channel optical glucose sensor is described. The sensing technology involves sampling of the interstitial fluid in a micro-fabricated chamber and measurement of the absorbance of the fluid in a non-destructive and reagent free manner. The glucose levels are estimated based on the absorbance data. This new technology relies on the unique optical characteristics of glucose in a near infrared spectrum. The sensor element will be implanted in the subcutaneous tissues of the human body. The data acquisition unit acquires optical data from the sensor and converts it into spectral data for processing. This new technology will be used as the sensing technology in a feedback controlled insulin delivery system for the in situ treatment of diabetes. The sensor-controller system together with an insulin pump will function as artificial pancreas and help maintain tight glycemic control in patients suffering from diabetes.
