Multi-electrode Electroretinography with Transparent Microelectrodes Printed on a Soft and Wet Contact Lens
A research group from Yamaguchi University and Waseda University has developed a small, transparent multi-point microelectrode that can be attached to commercially available contact lenses. Fabricated using semiconductor technology, this electrode possesses high light transmittance exceeding 82% and enables precise measurement of localized electrical signals in the retina.
The developed electrode exhibits excellent biocompatibility with a cell survival rate exceeding 95% and has been confirmed to have performance equivalent to commercially available electroretinogram (ERG) electrodes. This is expected to aid in the diagnosis of glaucoma and retinitis pigmentosa.
This research achievement, funded by AMED and the Canon Foundation, was published in the scientific journal “Advanced Materials Technologies” on May 7, 2024.
