Artifact‐Minimizing Ultrathin Transparent Electrodes Fabricated via iCVD for In Vivo Optogenetic Stimulation and Neural Signal Monitoring of Primary Visual Cortex (Adv. Funct. Mater. 42/2026)

Transparent Neural Electrodes This cover illustrates a transparent, flexible electrode array conforming to the brain surface, through which blue laser light passes unobstructed to optogenetically activate neurons beneath it and elicit neural signals for artificial vision. Using iCVD-deposited pDMAMS as a molecular adhesion layer, ultrathin 10 nm gold films achieve simultaneous optical transparency and electrical performance, enabling artifact-minimized optogenetic stimulation and neural recording.
