And for metal surfaces which are not self-sanitizing by nature, like steel, there are coatings which can be applied to achieve the same effect. This is often used in public transport.
One thing that I wondered after reading this, it mentions SARS but then it mentions killing bacteria, but SARS is a virus. Does this have any affects on viruses?
Cool idea and cool looking, but just want to point out that surface transmission of infections is several orders of magnitude less common than airborne transmission.
The TiO2 will likely rub off and need regular replenishment. Also, the alternative here, sensor-operated or button-operated automatic doors are already widely used. I wonder who this is meant for?
Sounds like a problem not worth solving? In my wework the handles get wiped down as per the cleanign protocol. Takes what, a second? The costs are marginal.
Wash your hands after touching the bathroom door, then lean on the door with your shoulder. If you have to use a door handle to exit the bathroom (the door swings into the bathroom), it means the bathroom is poorly designed, so use the paper towel that you dried your hands off with.
I use my elbow. It is the same recommendation as to cough to your elbow. You do not touch with your elbow on yourself or others so it is generally safe.
Unfortunately not always practical due to poorly designed handles and lock mechanisms. I usually "sacrifice" my little finger for this when I have to use my hands, with the theory that I'm much less likely to put that finger in my mouth or eye etc.
in iffy situations I use my fathers method, which is the systematic prevention of transfer, even if you must touch things or people (doctor,pathologist,forensics) in less than ideal circumstances, hard to describe, easy to demonstrate.
I suppose a second every few hours over dozens of doors adds up. And this has the benefit of being continual, so you don't get build up between cleans.
I'm sceptical myself that the tiny generator they have could produce enough energy, and that the coating they have won't be more of a hassle, but the idea is reasonable
I guess my "I still don't care about cookies" add-on prevents the pop-ups, but one of the other add-ons prevents the video from playing. Or the site is just broken.
Not sure how quickly the one from the post takes, but according to the Wikipedia article, brass disinfects "within two hours or less". I could see plenty of transmission within one to two hours. Perhaps it is a difference of speed?
Still, all regular handles, at least in hospitals, should be uncoated brass. Whenever I see chromed plated handles, slightly worn, exposing the brass below, I think "such a missed opportunity". It shouldn't have been plated to begin with.
What makes you think so? One of the section titles says "Your inspiration" (rather than "Our inspiration"), which sounds like ChatGPT was writing to them. That wasn't around in 2019.
