Electro-Enzymatic Sensor for Non-Invasive Glucose Measurement

In this article, a cost effective and simple electro-enzymatic sensor to measure glucose concentration non-invasively is proposed. Measurement of blood glucose concentration for early diabetes detection is one of the major health concerns. Usually, blood or other biofluid is collected by puncturing the finger or fore arm (invasive) which is a painful process. Hence, blood glucose measurement by non-invasive method is more desirable. Here, we propose a first step towards our final goal of non-invasive glucose measurement from human tears using contact lenses.
