Defence Research and Development Organisation (DRDO) developed Automatic Mist Based Sanitiser Dispensing Unit and UV Sanitisation Box and Hand-held UV device to fight against COVID-19.
Automatic Mist Based Sanitiser Dispensing Unit:
Centre for Fire Explosive & Environment Safety (CFEES), Delhi has developed an automatic mist based sanitizer dispensing unit. It is a contactless sanitizer dispenser that sprays alcohol-based hand rub sanitizer solution for sanitization of hands while entering the buildings/office complexes, etc. It is based on water mist aerator technology, which was developed for water conservation.
It operates without contact and is activated through an ultrasonic sensor. A single fluid nozzle with a low flow rate is used to generate aerated mist to dispense the hand rub sanitizer. The sanitizer will sanitize the hands with minimum wastage. Using an atomizer, only 5-6 ml sanitizer is released for 12 seconds in one operation.
UV Sanitisation Box & Hand-held UV device:
Defence Institute of Physiology & Allied Sciences (DIPAS) and Institute of Nuclear Medicine & Allied Sciences (INMAS) have designed & developed Ultraviolet C Light-based sanitization box and handheld UV-C (ultraviolet light with wavelength 254 nanometres) device.
The UV-C will destroy genetic material in COVID-19. The radiation warps the structure RNA which prevents the viral particles from making more copies of themselves. This is environment friendly and is a contact-free effective sanitization method.
