The use of VLSI to generate vision in blind people using a suitable neuroprosthesis implant of BIOMEMS in brain

In Human beings image processing occurs in the occipital lobe of the brain. The brain signals that are generated for the image processing is universal for all humans. Generally the visually impaired people lose sight because of severe damage to only the eyes (natural photoreceptors) but the occipital lobe is still working. In this paper we discuss a technique of generating partial vision to the blind by utilizing electrical photoreceptors to capture image, process the image using edge & motion detection adaptive VLSI network that works on the principle of bug fly´s visual system, convert it into digital data and wirelessly transmit it to a BioMEMS implanted into the occipital lobe of brain. The BioMEMS consists of an array of electrodes that generate the neuron potential which is similar to visually evoked potential of normal people by a resistor controlled we in bridge oscillator on it. Thus the neurons get the visual data from the BioMEMS which helps in generating partial vision or sight for the visually impaired patient.
