Sistema para avaliação da composição corporal através da bioimpedância

Abstract

This research approaches about a design of a system for measuring physical parameters by bioimpedance analysis. The paper discusses the operation of the method, the validity, the differences between the use of simple and multiple frequencies and the methods that have been used to perform these measurements. It is also made the presentation of the general scope of the system, which includes hardwares such as ez430Chronos development kit, the MSP430F5529, the CC1101 module and AFE4300 module. All the platforms used for the development of the system are presented and explained. It is also explained the particularities involved in each stage of the implementation of the final system. At the end of the work, the acquisition technique is applied in predefined bioimpedance models. In order to evaluate the results reached by the equipment, the measurement results obtained by the developed system are compared with its theoretical values with the aim of authenticate the readings. We have made a short discussion of the results in order to highlight the main difficulties involved in the technical application.
