A multifunctional transparent film that can be applied to 5G communication, smart buildings and autonomous driving was commercialized in South Korea. The transparent film with antenna, heat ray and light-emitting functions enables smooth 5G communication, high-efficiency heat diffusion and efficient information transfer.
The smart transparent film has been developed by a research team led by Lee Seung-seob, a mechanical engineering professor at the Korea Advanced Institute of Science & Technology (KAIST), and Yoon Jun-bo, a KAIST electrical engineering professor. Along with 5G antenna company Sensorview, South Korea's auto part manufacturer THN is developing automotive products using related technologies.
The prototype was selected for an annual technology exhibition event hosted by South Korea's Hyundai auto group. Lee was in charge of research on a transparent conductive film-based antenna and heat ray, and Yoon focused on the light-emitting function that can be used as lighting for future transportation. Using heat ray functions, the film with properties of low-power and high-efficiency heat dissipation can remove window frost and secure the view of external cameras.
The film's light-emitting function can be used for a transparent vehicle roof that enables drivers to look at the daytime sky and change its function to indoor lighting at night.
"The commercialization of the multifunctional smart transparent film designed for 5G communication and high-efficiency heat dissipation with the world's best performance will enable a wide range of applications such as smart buildings, smart factories and self-driving," Lee said in a statement on October 19. According to KAIST, the smart transparent film has the world's best performance with 90 percent transparency.
