The artificial retina system consists of a video acquisition device, a video processor, and an implant. The video acquisition device and processor are the external components of the system. The video acquisition device captures environmental images and transmits them to the video processor for analysis and processing. The processor generates retinal electrical stimulation encoding and sends it to the implant on the human retina in the form of radio frequency signals. The implant chip decodes the stimulation encoding and stimulates the residual optic nerve on the retina of blind patients through a two-dimensional implant electrode array, thereby producing light perception. At the same time, the video processor monitors its working status and battery usage in real time.

The prototype of the first-generation Nurotron artificial retina processor is small in size, convenient to carry and use, and has low power consumption. It employs grayscale processing and noise reduction techniques to ensure that the processed stimulation encoding is not affected by lighting conditions.

This product will fill the market gap in this field in China.
