Violeds technology achieves 99,9% COVID-19 sterilisation in 30 seconds

25 March 2020 Opto-Electronics

Seoul Viosys and Sensor Electronic Technology, innovators of compound semiconductor products and technology, announced that they had been successful in achieving 99,9% sterilisation of coronavirus (COVID-19) in 30 seconds. Tests were conducted with the research group of Korea University, Korea's top ranked university, by using light (photon) Violeds technology that is being mass-produced.

Violeds, compound semiconductor technology, is the brand name of technology that utilises UV LED for sterilisation and deodorisation functions. This technology has been developed by Seoul Viosys with SETi since 2005 to prevent germ proliferation through the use of a light source (photon) without the need of chemicals that could be harmful to humans.

Violeds technology, which has been recognised for its excellent sterilisation and stability, has also been used to clean environments for astronauts at NASA's space station in the United States. Until now, general commercial applications have been limited, as their lifetime was too short for prolonged use. However, since 2019, new patented technology has extended the previous life span by 50 000 hours, making it now an optimal solution for air purification and water sterilisation products.

CEO Chung Hoon Lee, who is the son of a farmer himself, said when Jimmy Carter, also the son of a farmer, became the president of the United States, it was a turning point in history. “I hope this success story will be a small but heart-warming story for small and medium-sized manufacturing companies and young start-ups who are dreaming of manufacturing.”
