Prosthetics For Retinal Stimulation

In a study recently published in Advanced Biomedical Engineering, researchers at Okayama University report a thin photoelectric film which can stimulate degenerated retinal tissues of the eye.

Using electric signals to stimulate tissues is the basis of several medical devices such as pacemakers for the heart or neurostimulators used for patients suffering from epileptic fits. A research team led by Dr. MATSUO toshihiko at Okayama University has developed OURePTM, a photoelectric dye-coupled thin-film device that generates electric potential changes when exposed to light. In their latest study, the research team reveals the ability of this device in stimulating degenerated retinal tissues.
