"A Comparative Dataset of Commercial Portable Brain Monitoring Devices for Research-Oriented Acquisition (2025)"

"This dataset presents 98 wireless brain monitoring devices (EEG and fNIRS) currently available on the global market. A scientific characterization was performed by systematically searching the literature following PRISMA guidelines and registered in the OSF. The search was conducted across five databases (IEEE, Scopus, PubMed, Web of Science, and Embase) to identify the applications of the devices tracked in the market. The searches were conducted between January and August 2025. A total of 5,069 records were screened; 3,164 were unique entries. Among these, 2,100 studies explicitly reported the use of brain devices in clinical trials, dataset development, or technology evaluations, with an overall inclusion rate of 66.37% after screening. Research adoption was quantified by the number of DOI-indexed publications referencing each device. The compiled dataset provides an evidence-based framework to guide neuroscientists, engineers, and clinicians in selecting the appropriate device for their specific research needs."
