Synopsis:
Covid-19 has increased the need for sterilization tools/equipment/media so that its spread can be minimized. One of the commonly touch area that requires specific sterilization equipment is door handles. Disinfecting and sterilizing are types of decontamination, a process that makes something safe to touch. The purpose is to kill enough germs so the risk of infection, in this case Covid-19, is extremely low. As a team, you will need to design and build a self-sterilize door handle device so that once the handle is touched by contaminated hand, it will immediately sterilize/disinfect itself by means of disinfection spray/UV light (you will not use an actual UV light due to safety concerns) etc.
