Nanostructured Platinum Boosts Dry Microneedle EEG Performance

Researchers developed a scalable silicon microneedle electrode using mechanical dicing, KOH etching, and nanostructured platinum to improve dry EEG recording without conductive gels. The nanoPt coating increased electrochemically active surface area by about 15-fold, reduced electrode-skin impedance, and improved proof-of-concept EEG signal quality compared with non-nanostructured platinum-coated microneedles, although conventional wet electrodes still performed better.
