Development of low cost wireless biosignal acquisition system for ECG EMG and EOG

A biosignal is a human body variable that can be measured and monitored continuously and provide information about the health status. Among them well known bioelectrical signals are Electrocardiograph (ECG), Electromyography (EMG), Electroencephalogram (EEG) and Electrooculogram (EOG). Those signals are useful for different applications like disease diagnosis, human machine interface, entertainment. This paper presents a low cost, wireless biosignal acquisition system specialized for ECG, EMG and EOG. In this system, Arduino Uno in used and an application is developed for visualizing and storing the signal in real-time. This application is developed by processing. It stores the signal data in a text file, which can be used in MATLAB for analysis. In this system, biosignal is transferred by Bluetooth serial communication, which ensures safety and reduces noise interference. This system can be used either Windows, Linux, Mac OS and suitable for both laptop and desktop computer.
