IIT-Guwahati develops low-cost UVC LED-based disinfection system; comes out with waterproof fabrication material required for PPE amid global COVID-19 crisis
Guwahati: Indian Institute of Technology (IIT) Guwahati has developed a low-cost UVC LED-based disinfection system amid the coronavirus pandemic in the country.
The team is also addressing the critical need of a material -- a fabrication material with waterproof ability -- required for personal protective equipment (PPE).
Prof TG Sitharam, director, IIT Guwahati, has formed a research team led by Dr Senthilmurugan Subbiah of the department of chemical engineering to work in collaboration with Excel Tech of Bengaluru and Ultimate Aeroaqua Filter of Guwahati to develop the two technologies.
Speaking about the efforts that are being made by the research team, Dr Subbiah said, “IITG community is focused to work closely with government agencies and industrial partners to develop smart and low cost technologies to fight against COVID-19.”
UVC system is a proven technology to sanitise the microorganism infected non-porous surface. Almost 90% killing rate can be achieved by UVC for one of the highly stable virus MS-2 Coliphase with 186 J dose, whereas 36 J dose is needed for influenza virus which is similar to COVID-19.
According to the research team, one of the critical requirements that COVID PPE fabrication material should have is a waterproof ability.
As a research institute, IIT Guwahati is providing technical support to identify the best waterproof material from the Indian market and its performance. With identified material, the industrial partner has produced a sample PPE for further waterproof testing.
Further, IIT Guwahati team will be exploring potential technology for antimicrobial coating on PPE to reduce the viral load on PPE during exposure to COVID-19.
The PPE kit includes a jumpsuit, face shield, mouth mask, head covers, gowns and shoe covers.
