A team from the Indian Institute of Technology (IIT) has developed an inexpensive LED-based machine that can be used to disinfect floors in hospitals, as well as buses and trains to help combat COVID-19 support the country. IIT Guwahati is also filing a patent machine, which will be available for Rs 1000 after commercialization. The current prototype of the machine will need to be manned manually, but the team is working to turn it into a robotic machine that will require limited human intervention.

The machine developed at the request of the government of Karantaka and which will be used in hospitals and buses is now being offered for commercial purposes to other governments. “Disinfection of public places will be very crucial in the coming months if movements are not restricted, but the necessary precautions must be taken to prevent the spread of viruses. From now on, the disinfection measures will only be taken on surfaces, walls and open spaces is not yet a floor sanitizer system unless someone decides to manually mop the floor with an alcohol-based cleaner, & # 39; Senthilmurugan Subbiah, associate professor in the Institute’s Chemical Technology department, told PTI.

“UVC system is a proven technology to clean the non-porous surface infected with microorganisms. A 90 percent UV kill rate can be achieved by one of the highly stable viruses MS-2 Coliphase with a dose of 186 J while a dose of 36 J is required for Influenza virus which is comparable to COVID-19. “The team has developed a UVC LED system that can deliver a dose of 400 J in 30 seconds so that a virus-contaminated surface will be purified. The unique design of this UVC system ensures uniform exposure in a virus-infected non-porous area, “he added.

The machine, which has been tested in the institute’s laboratory, is also equipped with an object movement identification feature, avoiding UVC exposure to human skin during surgery. “We are working closely with government agencies and industry partners to develop several other smart and low-cost technologies to combat COVID-19,” said Subbiah. The death toll from new coronavirus has risen to 114, and the number of cases in the country rose to 4,421 on Tuesday, according to the Union Ministry of Health.

While the number of active COVID-19 cases was 3,981, as many as 325 people were healed and discharged, and one had migrated. The total number of cases includes 66 foreign nationals.
