Recently, the team led by Zhou Feichi from the School of Microelectronics at the Southern University of Science and Technology (SUSTech) has achieved a major breakthrough in the field of wide-field-of-view monocular 3D perception computing, with relevant findings published in Nature Communications. This study introduces, for the first time, a wide-field-of-view anisotropic optically controlled resistive random-access memory (AORRAM). By utilizing zinc oxide nanowire arrays with axially graded oxygen vacancy gradients, the system achieves monocular 3D motion perception and localization within an ultra-wide 140° field of view. The AORRAM device leverages the differential light absorption and electron trapping behaviors generated by light at various incident angles at the nanowire interface, resulting in angle-dependent non-volatile multilevel conductance modulation characteristics. This enables the simultaneous acquisition of two-dimensional contour and depth temporal information without the need for binocular lenses. The research team constructed a hardware system composed of an AORRAM array and a gated recurrent unit (GRU), achieving a recognition accuracy of 95.41% for 12 types of motion scenarios in complex noise environments, significantly outperforming traditional neural networks. This technology breaks through the two-dimensional information acquisition limitations of traditional vision devices through nanowire gradient defect engineering, providing a high-performance, low-power three-dimensional visual perception solution for edge intelligence devices such as drones and autonomous vehicles.
