Abstract:
1. An implantable device to interface with neuron cells, the device comprising: an array of pixel units configured to stimulate the neuron cells, the pixel units configured to operate in a mode of operation selected from a plurality of modes including a normal mode and a calibration mode, the pixel units including configuration settings; an interface configured to receive external commands in the calibration mode to update the configuration settings; and a control circuitry configured to switch the modes of operation for the pixel units, wherein during the normal mode, the pixel units are configured to receive light for the stimulating the neuron cells to enable perception of the light, and wherein during the calibration mode, the pixel units are configured to adjust amount of stimulation to the neuron cells, wherein the pixel units detect responses from the stimulated cells in the calibration mode and wherein the adjustment is based on the responses detected, wherein each pixel unit comprises an electrode, a photo sensor, a processing circuitry, and an electric sensor, the photo sensor configured to receive the light, the electrode configured to stimulate targeted one or more of the neuron cells, the electric sensor configured to receive electric current from the targeted neuron cells, wherein the processing circuitry is configured to
