This setup allowed us to assess the influence of all three factors on the variance of data. We recorded four subjects three times with each of the four EEG systems. We tested four EEG systems: two standard research-grade systems, one system designed for mobile use with dry electrodes, and an affordable mobile system with a lower channel count. We sought to determine how variance across systems compares to variance across subjects or repeated sessions. However, many low cost and mobile EEG systems are now available, and there is some doubt as to the how EEG data vary across these newer systems. It is often assumed that the specific choice of EEG system has limited impact on the data and does not add variance to the results.

Lab-based electroencephalography (EEG) techniques have matured over decades of research and can produce high-quality scientific data. The proposed device, on top of satisfying noise level and accuracy of detected artifacts in the signal, was also tested and confirmed to successfully resist the effect of electromagnetic interference, successfully detect the alpha brain wave, and detect the P300 paradigm. According to its characteristics, the device is compared to the signal-to-noise level of the ADS1299 device produced by Texas instruments and used for comparison in this paper. In this paper, we aim for yet further cost reduction by proposing a Raspberry PI -based device for reading EEG signal. Even then, the cost of these devices often exceeds IOOOUSD. In recent years, several companies started manufacturing devices capable of recording EEG signals using non-invasive electrodes at low cost. As a result, popularity of brain-computer interface devices used for recording brain signals at low-cost has increased dramatically. It also affected neuroscience, where machine learning made possible to find practical use for electroencephalogram signals in the brain in various fields of engineering. Over the past decade, advances in artificial intelligence have expanded and reshaped many industries. The paper presented the easiest way to the neuroscience world with a shield for RaspberryPI - PIEEG. With 6.59 microvolts peak-to-peak input referred noise and a −97 dB common mode rejection ratio in 0–70 Hz band, the proposed design can be qualified as a low-cost precision cEEG research device.

While conducted tests confirm the validity of the system against official datasheet specifications and for real-world applications, the proposed quality verification methods can be further employed for analyzing other similar EEG devices in the future. Furthermore, simple but effective assessment techniques were used for system evaluation.

The ability to capture 16 to 64 EEG channels at sample rates from 250 Hz to 1000 Hz and to transfer raw EEG signal over a Bluetooth or Wi-Fi interface was implemented. The introduction of this novel, vertically stackable board allows the EEG scaling problem to be solved by effectively reconfiguring hardware for small or more demanding applications. To eliminate this problem, this paper presents the design and evaluation of a compact, modular, battery powered, conventional EEG signal acquisition board based on an ADS1298 analog front-end chip. The lack of scientific analysis for such system design, modularity, and unified validation tends to suppress progress in this field and limit supply for new low-cost device availability. The increased popularity of brain-computer interfaces (BCIs) has created a new demand for miniaturized and low-cost electroencephalogram (EEG) acquisition devices for entertainment, rehabilitation, and scientific needs.
