摘要： The invention relates to a retina implant (10) for the functional electric stimulation of a retina (16) according to incident light (18). The retina implant (10) comprises a stimulation chip (30) that is configured so as to be implanted in the area of the retina (16) of an eye (12), and a radiation receiver (32) which supplies power for the stimulation chip (30) according to non-visible incident radiation (24). According to one aspect of the invention, the radiation receiver (32) is embodied so as to be implanted at a distance from the stimulation chip (30) in the area of the eye (12). The stimulation chip (30) is provided with decoupling means in order to separate non-visible scattered radiation (36, 38) from incident visible light (18).

摘要： The invention concerns an electrode arrangement (10) for electrically stimulating biological material (16), comprising at least a stimulating electrode (12) for delivering a stimulus signal to the biological material (16). The electrode arrangement also comprises a counter-electrode (14) which constitutes a pole opposite to the stimulating electrode (12). The invention is characterized in that said electrode arrangement further comprises a detection electrode (18) for determining a polarizing voltage of the stimulating electrode (12).
