“Artificial eye” detects any movement, and also remembers and analyzes it

Chinese scientists have created a device that detects and recognizes moving objects. Researchers were inspired by the work of the human eye. The results of the work are presented in the journal Nature Nanotechnology.

Researchers at Fudan University and the Chinese Academy of Sciences have recently developed a new two-dimensional (2D) device inspired by the human retina. It not only detects any movements, but also stores data about them, and then analyzes them. This versatile device is not as bulky as its counterparts, but at the same time it detects moving objects with high accuracy. The system works like an “artificial eye”, but in reality it is a surveillance device, not an implant.

Devices that can automatically detect and recognize moving objects can be used to improve remote environmental monitoring. Most of the existing technologies for motion detection and recognition (MDR) are based on image sensors made from additional metal oxide semiconductors (CMOS). Compared to the human retina, these systems are very cumbersome and ineffective. This is because they require multiple hardware components to capture, store, and process images.

The “artificial eye” created by Chinese scientists partially resembles the human retina. Therefore, the authors of the development appreciated its ability to perform some of its functions. It turned out that the artificial neural network, which ran on a device inspired by the retina, recognizes moving objects with greater accuracy than algorithms running on other devices.
