    Area of Science:

    • Neuroscience
    • Biomedical Engineering
    • Materials Science

    Background:

    • Current clinical brain surface electrodes have limitations in spatial resolution (10 mm spacing) and conformability, hindering precise functional brain mapping.
    • Unconformable electrode sheets can fail to capture cortical activity, impacting the quality of electrocorticographic (ECoG) signals.

    Purpose of the Study:

    • To develop implantable, personalized sheet electrodes for higher quality ECoG signals.
    • To improve functional brain mapping and the performance of brain-machine interfaces (BMIs).

    Main Methods:

    • Personalized molds were created using 3D-printing for custom sheet electrode fabrication.
    • Electrode arrays were designed to conform to brain surface curvature and inter-electrode distances were reduced to 2.5 mm.
    • Rat experiments were conducted to assess long-term toxicity, and efficacy was confirmed in an amyotrophic lateral sclerosis patient.

    Main Results:

    • Personalized electrodes were successfully custom-designed, rapidly manufactured, and safely implanted.
    • The electrodes achieved inter-electrode distances of 2.5 mm, offering improved spatial resolution.
    • High gamma-band information was successfully acquired in an amyotrophic lateral sclerosis patient, demonstrating clinical utility.

    Conclusions:

    • Personalized, conformable sheet electrodes significantly enhance ECoG signal quality for functional brain mapping.
    • These electrodes demonstrate safety and efficacy, paving the way for improved BMI performance.
    • The developed technology offers a promising advancement for neuroprosthetics and neurological research.
