Protótipo de um EEG portátil de três canais

Abstract

This work aims to present the project of development and signal analysis of a portable electroencephalography equipment, comparing it to the current literature. The project consists of designing and constructing a three-channel electroencephalography device capable of picking up signals from the occipital part of the head and then displaying it on a programmed C# interface, after passing it though a filtering process. In addition, the collected signal can be saved to extract characteristics of itself, making it possible to use the file in other existing softwares, increasing the possibilities of complementary studies. It was not possible to treat the signal with the developed plate, due to factors explained throughout the text, but with this work there was an accumulation of knowledge in the area of instrumentation, which is disseminated to other students through this dissertation. This prototype, after some adjustments and tests, will be later used in a future study which is basically the development of a type of command to disabled people, using visual signals, which are more intense in the occipital region of the skull, interpreted by the brain and captured by the device.
