Overview

This chart provides a visual and tabular comparison of EEG devices based on their signal-to-noise ratio (SNR) and price. Devices are categorized into consumer, research, clinical, and implantable groups. Estimated values, indicated by asterisks (*), are used when manufacturer specifications are unavailable.

This web application provides a comprehensive comparison of EEG devices based on their signal-to-noise ratio (SNR) and price. It is designed to assist researchers, clinicians, and consumers in selecting the most suitable device for their needs. The interactive chart and sortable table allow for easy exploration of device specifications and categories.

How to Use

Use the checkboxes above the chart to filter devices by category (e.g., consumer, research, clinical, implantable). The autoscale options for the X-axis (SNR) and Y-axis (Price) can be toggled to adjust the chart's scale dynamically. Hover over points on the chart to view detailed information about each device. The table below the chart can be sorted by clicking on the column headers.

Future Directions

Future updates to this application may include additional device parameters such as electrode count, sampling rate, and connectivity options. We also plan to integrate user reviews and real-world performance data to provide a more holistic view of each device's capabilities. Expanding the dataset to include emerging technologies and devices will ensure the tool remains relevant in the rapidly evolving field of biomedical data acquisition.

Note on Neuralink: While Neuralink is not yet commercially available, it is designed as a bidirectional brain–computer interface. This includes high-fidelity recording and planned future support for electrical stimulation. Current trials focus on recording only.
