Light intensity controlled photoelectrochemical switches for pattern recognition

In the present world, a lot of attention is paid to the search for new solutions for information processing. From the human point of view, the most information from the world around us is provided by the sense of sight. Biologically, the normal life of humans begins cannot be separated from vision, and the content of vision depends on the light reflected on the surface of things. Evidence has suggested that humans receive the most information through the visual perception system. Therefore, the concept of using light for the conversion of information is very popular nowadays. Scientists try mimicking the human brain and use artificial synapses to build optoelectronic devices. Nerve synapses can transmit information, but they also can remember information. These properties mean that synapses can be used for pattern recognition. Chemicals could behave as nerve synapses and optical synapses could realize the interconversion between optical and electrical signals. It is very important and could develop the concept of bionic vision.
