Abstract

Methods for fabricating analyte sensor components using IC- or MEMs-based fabrication techniques and sensors prepared therefrom. Fabrication of the analyte sensor component comprises providing an inorganic substrate having deposited thereon a release layer, a first flexible dielectric layer and a second flexible dielectric layer insulating there between electrodes, contact pads and traces connecting the electrodes and the contact pads of a plurality of sensors. Openings are provided in one of the dielectric layers over one or more of the electrodes to receive an analyte sensing membrane for the detection of an analyte of interest and for electrical connection with external electronics. The plurality of fabricated sensor components are lifted off the inorganic substrate.

Description

technical field [0001] The present invention relates generally to analyte measurement systems and methods, and more particularly to methods of fabricating analyte sensors using microfabrication and exfoliation techniques. Background technique [0002] Controlling blood glucose levels in diabetics and other patients is a critical component in critical care, especially in the intensive care unit (ICU), operating room (OR) or emergency room (ER) setting where time and precision are critical middle. Currently, one of the most reliable ways to obtain high-precision blood glucose measurements from patients is through the direct time-point method, which is an invasive method that involves drawing a blood sample and sending it out for laboratory analysis. This time-consuming approach often does not produce the desired results in a timely manner. Other less invasive methods, such as finger pricks, involve pricking the skin with a lancet or pin to obtain a small sample of blood, whi...
