Abstract

"IMPLANTE RETINAL MICROFOTODETECTOR MULTIFáSICO COM CAPACIDADES DE CORRENTE E VOLTAGEM VARIáVEL E APARELHO PARA INSERçãO". A presente invenção refere-se a um implante retinal (10) para eletricamente incluir visão formada em um olho que inclui uma composição de microfotodetectores empilhados dotados de uma camada de pixel sensor de imagem (60) e uma camada de ajuste de ganho de corrente e voltagem (100). Um primeiro filtro de luz (74) é posicionado em um dos microfotodetectores de cada um dos pixels sensores de imagem do implante, e um segundo filtro de luz (75) é posicionado no outro dos microfotodetectores no pixel sensor de imagem do implante, cada um dos microfotodetectores do pixel responde a um diferente comprimento de onda de luz para produzir uma sensação de escuro e de luz. Um terceiro filtro (106) é posicionado em uma porção da camada de ajuste de ganho de corrente e voltagem que está exposta à luz para permitir o ajuste do ganho de corrente e de voltagem do dispositivo.
