Cortical Grid Electrodes Market Report 2026

The cortical grid electrodes market size has grown strongly in recent years. It will grow from $1.14 billion in 2025 to $1.25 billion in 2026 at a compound annual growth rate (CAGR) of 9.4%. The growth in the historic period can be attributed to increasing demand for neuroprosthetics, growing funding for neurological research, rising prevalence of neurological disorders, expanding applications in brain-computer interfaces, technological advancements in electrodes.

The cortical grid electrodes market size is expected to see strong growth in the next few years. It will grow to $1.77 billion in 2030 at a compound annual growth rate (CAGR) of 9.2%. The growth in the forecast period can be attributed to rising demand for neurological treatments, growing applications in brain research, increasing investments in research and development, expansion of clinical adoption, rising focus on personalized neuromodulation therapies. Major trends in the forecast period include technology advancements in miniaturization of electrodes, innovations in conductive polymer materials, developments in high-density electrode systems, research and developments in AI-based brain mapping, advancements in integration with neurosurgical platforms.

The increasing prevalence of neurological disorders is expected to drive the growth of the cortical grid electrodes sector in the coming years. Neurological disorders are medical conditions that impact the brain, spinal cord, and nerves, causing a variety of symptoms, including cognitive, motor, and sensory impairments. The rise in neurological disorders is associated with the aging population, as aging gradually diminishes neuronal function, reduces brain plasticity, and increases oxidative stress, contributing to the onset and progression of these conditions. Cortical grid electrodes assist in treating neurological disorders by enabling precise monitoring and stimulation of brain activity to restore or regulate neural function. They enhance patient outcomes by supporting targeted therapies for conditions such as epilepsy, movement disorders, and chronic pain. For example, in July 2024, the National Health Service, a UK-based government agency, reported that 487,432 patients were diagnosed with dementia (a progressive brain disorder affecting memory, thinking, and daily activities) by June 30, 2024, reflecting an increase of 3,155 cases compared to May 31, 2024. Consequently, the growing prevalence of neurological disorders is fueling the expansion of the cortical grid electrodes sector.

Leading companies in the cortical grid electrodes sector are concentrating on developing advanced products, such as high-density thin-film electrode arrays, to improve the resolution and safety of neural recording. High-density thin-film electrode arrays employ flexible, biocompatible substrates like polyimide to create micro-electrode arrays that closely conform to the brain’s surface, enabling the recording of thousands of neural data channels with minimal tissue displacement and reversibility, thereby addressing the limitations of traditional rigid subdural grids. For example, in March 2025, Precision Neuroscience Corporation, a US-based brain-computer interface company, obtained Food and Drug Administration (FDA) 510(k) clearance for its Layer 7-T (Layer 7 Cortical Interface). The device is a high-density thin-film 1024-channel cortical electrode array intended for temporary use (less than 30 days) to record, monitor, and stimulate electrical signals on the brain’s surface. The system allows surgeons to map brain activity with unprecedented resolution using a minimally invasive micro-slit technique, supporting the preservation of eloquent tissue during neurosurgical procedures.

In November 2024, Nihon Kohden Corporation, a Japan-based manufacturer of medical electronic equipment, acquired a 71.4% stake in NeuroAdvanced Corp., the parent company of Ad-Tech Medical Instrument Corporation (AdTech), for an undisclosed amount. With this acquisition, Nihon Kohden intends to integrate Ad-Tech's specialized intracranial electrodes, which are used for epilepsy treatment and neurodiagnostic procedures, with its own established electroencephalogram (EEG) systems. Ad-Tech Medical Instrument Corporation is a US-based provider of long-term monitoring cortical electrodes and neurosurgical accessories.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs have influenced the cortical grid electrodes market by increasing the cost of imported medical-grade materials and specialized manufacturing equipment. this has affected production efficiency and pricing, particularly in regions such as north america and europe, where manufacturing depends on global suppliers. segments like high-density and flexible cortical grid electrodes face the highest impact due to their complex designs. on the positive side, tariffs are encouraging local manufacturing initiatives and innovation to produce cost-effective solutions domestically.

Cortical grid electrodes are medical devices intended to be positioned directly on the brain’s surface to record or stimulate neural activity. They comprise an array of small electrodes embedded within a flexible grid that adapts to the contours of the brain. These electrodes are mainly utilized for monitoring brain signals and supporting neurological research and clinical procedures.

The key products in cortical grid electrodes include epidural cortical grid electrodes, high-density grid electrodes, flexible grid electrodes, penetrating electrodes, multi-contact electrodes, customized electrodes, and reusable electrodes. Epidural cortical grid electrodes are implantable devices placed beneath the dura mater to record or stimulate neural activity with high spatial precision while minimizing tissue damage. Materials include silicone, polyimide, metals, and conductive polymers. Electrode configurations include strip, grid, cylindrical, and custom designs.
