System Codesign for the Measurement of Biological Tissues using Surface Potential Data Analysis

Abstract

In this work we present the development of a monitoring system that is targeted to track the data of electrical potential measurements in biological tissues. The system is conceived to be portable and its design allows for low-energy consumption. To account for different types of biological materials, the measurement of the bioimpedance of the material is generally used. To achieve both speed and accuracy, we deploy a system using hardware-software codesign with reconfigurable hardware. This integral approach is facilitated by the use of a modern system of chip with mixed signal capabilities. In particular we use a field programmable gate array for accelerating signal processing and data acquisition. A double core microcontroller is used to collect, process and deliver the data over a networked environment.
