The device that imitates the work of the brain cells responsible for the sight of a person


Researchers have developed a device from nanomaterials, which simulates the neural pathways of the human brain cells used for sight. In the future, this will create neurorphic computers that can simultaneously process and memorize information.

Currently, robotics and automated equipment needed cameras or remote servers that receive visual information and transmit it to the processing device. However, the invention of the team from the University of Central Florida actually imitates the features of the eyes and the brain, which will allow making cars truly autonomous.

The essence of innovation lies in the cultivation of nanoscale photosensitive quantum dots perovskite on a sheet of graphene with a thickness of one atom. This allows photoactive particles to capture light, convert it into electrical charges and then transmit them directly to graphene in one step. Such nature of behavior demonstrates the effect of light memory and is similar to brain cells associated with vision.

During the test of the device’s ability to see objects with neuromorphic calculations, the researchers used it in experiments on the recognition of persons. They found that their invention successfully recognized the face of four different people.

According to scientists, this technology opens the way to develop ultra-thin optoelectronic devices, devices to improve vision and more efficient ways of storing and processing information.
