Professor Kim Joon-dong of our university (President, Park Jong-tae) said that using transparent semiconductor technology, we have developed a flexible and transparent visual recognition platform that resembles human visual functions

The newly developed artificial photoreceptor has the characteristic of simulating the function of the human eye and has the advantage of operating without external power. This is a two-way technology that absorbs ultraviolet rays, which are environmentally harmful factors, to create electrical energy, and at the same time, light in the visible light area is transmitted and transparent and operates on light in the human detection range.

It absorbs ultraviolet rays to generate photovoltaic power, supplies electricity on its own, and expresses its ability to detect the range of human color configuration. In addition, the 150o measurement range of the wide field-of-view greatly exceeds the visual range (105o) of the human eye, which can be utilized in the human interface to greatly improve the acquisition and processing of information.

Based on the transparent light-electric energy exchange function, this technology has reported the fastest response characteristics (less than 1/1000 seconds) in transparent devices, and is expected to be applied to various fields such as human interface-based electronic devices, invisible communication, effective energy control, and biological devices.

One of the characteristics of the developed technology, the selective absorption technology of light using transparent semiconductors, aims to commercialize 'transparent energy film' by effectively blocking UV rays harmful to humans and efficiently controlling energy in the residential environment.

This technology was derived through the Environmental Technology Convergence Innovation Project (Task Name: High-Performance Transparent Energy Film with Environmental Hazardous UV Protection Function) in Gangseo-gu, Incheon. Lee Hee-kwan, head of the business division, said, "It is meaningful that we derived the practical use of research through technology matching of special zones (linked between our universities and specialized companies), and we will support entering commercialization in the future.“

In this development, Priyanka Bhatnagar (the Department of Electrical Engineering at our university) participated in key research and development, and it was published in InfoMat (Impact factor: 24.798), a well-known journal in connection with academic research and industrial technology.
