• abstract: This work describes the architecture and realisation of microelectronic components for a retina implant system that will provide visual sensations to patients suffering from photoreceptor degeneration. Special camera circuitry has been developed for a high dynamic range of more than seven decades of optical resolution corresponding to the performance of the human eye. This image is converted into receptive field data for generation of the stimulation data. The former components are located outside of the eye and are wireless linked to an implanted flexible silicon multielectrode stimulator inside the eye, which generates electrical signals for electrostimulation of the retina. The image sensor and the implantable power and data receiver as well as the stimulator have been fabricated using standard CMOS-technology.
