Design of capacitive pressure sensor for continuous glucose monitoring system

Capacitive sensor is best suitable sensor for the fabrication. In this study, we used Finite Element Method (FEM) tool to design and simulate capacitive pressure sensor based on the nob-linearity and sensitivity aspects. The sensor consists of parallel plates which is electrodes made up by optimizing two sensing devices that is microbridge and micro-cantilever with three different materials aluminium, gold and platinum. Among those aluminium is better due to its non-linearity and cost. The suitable sensing element is integrated into pressure sensor in order to measure the variation in glucose concentration levels.
