Title
Abstract
The evolution of nature for hundreds of millions of years has brought us a colorful biological world. Various micro-nano structures in biological organisms constitute organs with different functions. The various sensory organs have powerful information collection capabilities and adaptability, whose design can well inspire human beings to manufacture efficient functional devices. This talk will summarize our group's recent research on nanowire array based bionic eye devices and nanostructured electronic nose (E-nose) devices. The bionic retina utilizes an ultra-dense array of optoelectronic nanowires grown in a hemispherical porous template. Nanowires could mimic the visual perception cells in the human eye. The devices feature ultra-wide field of view, and can sense visible and mid-infrared light, as well as color distinguish capability. They can have potential applications for future robotics and autonomous systems. Meanwhile, the talk will also introduce our research on nanostructured chemical sensor arrays and high-performance smart bionic E-nose systems. By combining semiconductor nanotube sensor arrays and artificial intelligence algorithms, the identification of multiple gases can be achieved. This sensor system can meet the urgent needs of distributed environmental monitoring in smart homes, smart buildings and smart cities, and can also be used in mobile and wearable devices in the future.
