Electroencephalography (EEG) Devices Market Size Worth USD 3,492.03 Million by 2034 | CAGR: 9.5%

The electroencephalography (EEG) devices market size is expected to reach USD 3,492.03 million by 2034, according to a new study by Polaris Market Research. The report “Electroencephalography (EEG) Devices Market Share, Size, Trends, Industry Analysis Report: By Product (8-channel EEG, 21-channel EEG, 25-channel EEG, 32-channel EEG, 40-channel EEG, and Multichannel EEG), By Modality, By Application, By End Use, and By Region; Market Forecast, 2025–2034” gives a detailed insight into current market dynamics and provides analysis on future market growth.

Electroencephalography (EEG) devices are non-invasive medical instruments used to measure and record the electrical activity of the brain. These devices detect voltage fluctuations resulting from ionic current flows within the neurons of the brain through electrodes placed on the scalp. The electrodes capture the brain’s electrical signals, which are then amplified and digitized for analysis on a computer. EEGs are particularly useful for monitoring brain activity in real time. EEG devices are widely used in both clinical and research settings.

In medicine, these devices help diagnose neurological disorders such as epilepsy, sleep disorders, brain tumors, and encephalopathies by identifying abnormal brain wave patterns. They are also used during surgery to monitor brain function and in the evaluation of brain death. In neuroscience research, EEGs aid in investigating cognitive processes such as attention, memory, and perception. Additionally, EEG technology has expanded into emerging fields such as brain-computer interfaces (BCIs), where it enables users to control external devices with their thoughts, offering potential applications for individuals with disabilities. Portable and wearable EEG devices have further expanded their applications in consumer markets, including neurofeedback training, meditation aids, and mental wellness monitoring.
