| titleOfInvention | Charge-integrated artificial retina and method |
| abstract | An artificial retina is provided that provides power control capability through the temporary accumulation of charge. The artificial retina includes at least one stimulation unit, and each stimulation unit sequentially includes an optical relay element (for example, a photodiode) that is in electrical communication with the electrode. The pulse generation circuit supplies a reverse bias signal to the optical repeater, and occasionally supplies a pulse forward bias signal to the optical repeater. While applying the reverse bias signal, charges are accumulated by the incident light to the optical repeater element. By providing a pulse forward bias signal, the accumulated charge is injected through the electrode into the retinal tissue adjacent to the electrode, thereby stimulating the retina. Appropriate selection of bias signal parameters ensures that a sufficient amount of charge accumulates and reaches the stimulation threshold. Thus, controlling the stimulation current is improved while leaving the advantage of utilizing the natural focusing and imaging capabilities of the eye. |
