A microwave metamaterial inspired sensor for non-invasive blood glucose monitoring

Abstract

In this paper, a microwave sensor based on an artificial transmission line is proposed for non-invasive blood glucose monitoring. A corresponding numerical model of the sensor implemented in microstrip technology is created in the commercial full-wave numerical simulation tool COMSOL Multiphysics and virtually tested by means of numerical simulations. Blood-glucose solution models with various blood glucose concentrations are used as a model of a biological tissue under test. Furthermore, a possible methodology for performing non-invasive tests is proposed. Sensitivity of the sensor developed here is compared to a sensor based on a section of a conventional microstrip transmission line of the same length and width.
