Recent advances in bioinspired vision sensor arrays based on advanced optoelectronic materials

Animals can learn about the outside world in many ways, and the visual organ is a key organ for acquiring information about the outside world. With the continuous development of intelligent technology, artificial vision techniques are becoming easier and more automated; however, the rigidity, process complexity, and complicated optical components of traditional commercial photodetectors have hindered their development in bionic vision. In recent years, a new generation of optoelectronic materials has attracted extensive research due to their simple preparation process, continuously tunable bandgap, and excellent optoelectronic properties. Two-dimensional optoelectronic materials and perovskites have become the most promising and effective optoelectronic materials for next-generation optoelectronic devices. Based on the excellent properties of next-generation optoelectronic materials, they have also triggered intensive exploration by researchers in the field of visual bionics. This paper highlights a review of the latest research progress of next-generation optoelectronic materials, including their preparation methods, working mechanisms, structural designs, and advances in the field of imaging. The applications of new generation optoelectronic materials in visual bionics by simulating biological visual structures are also described. Finally, the prospects and challenges for the development of next-generation optoelectronic materials in the emerging field of bionic vision are discussed.
