NeuroSpy: A low-cost portable IoT enabled EEG and ECG data processor

Different commercial portable electroencephalography (EEG) monitoring devices are available in the market, but these devices are expensive. Product service availability from these devices is based on the monthly/yearly subscription basis, which is not budget-friendly to people from developing countries. In this paper, a portable, cost-effective system 'NeuroSpy' using off-the-shelf jellybean components has been designed, which is functionality-wise similar to commercially available devices from different vendors. The developed system has production and implementation costs significantly lower by a factor of ~ 2.22- 90 than the traditional commercial devices. This system can extract different biomedical signals such as electroencephalogram and electrocardiogram and monitor the human body temperature in real-time. We can use this multifunctional battery-powered portable biomedical signal recorder to monitor sleep conditions, analyze symptoms of various diseases such as encephalitis, epilepsy, coma, and so on. Another use of this kind of device is to interface (BCI) with computers through brain waves of the human body, which may help disabled people. This system is Internet of Things (IoT) enabled; thus, we can store captured data into a central database for further analysis.
