Why not a door you can push open both ways?
You have to let the engineers over-engineer. It's a healthy release.

#52I have copper light switches and other fittings and was interested to learn they have the same useful property.

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.
Citation? Microban et al are marketing bunk.
Microban is a company, not a product, and they make a wide range of products, some of which are zinc or silver based coatings and effective in slowing the growth of bacteria and fungus.

And then grabbing the bathroom door handle.
With my sleeve. (Although I did see a lot of foot-operated door handles emerge on public restroom doors during the covid years. They're mounted down low, near the floor, and you can just put your shoe on them and drag the door open without using hands. They make sense to me for what I think are a lot of good reasons.)
The Metro (trains) stations in my city have foot-operated levers (pedals) to control the elevators/lifts, doors, toilet taps/faucets (though the urinal themselves have sensors to auto-flush), etc.
Although, as a precaution, I carry a hand-sanitizer and fresh mask in my bag whenever I commute on such public transportation.
I guess the pandemic (and the eerie realisation that it can repeat anytime, since it was decidedly an artificial one) has attuned me to be more vigilant on my safety and health, so I try to be cautious and safe in public where crowds can gather.

#56I was expecting it to just dispense hand sanitiser gel straight onto the handle.
I suppose this is a more practical take.

#57Many public buildings and elevators in Hong Kong installed wireless controls, simply wave your hand in front of a little hole (ultrasonic sensor?) next to the floor button you want to go to. Curious to find out in which mall they installed this in!
Re: Self Sanitizing Door Handle
#58Cool 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.
If we're talking sanitation tech: I'm personally really excited by the further miniaturization of (far)-UVC light sources [1]. Far-UVC lamps deactivate airborne pathogens, but cannot penetrate the human eyes or skin making them generally safe to use.
Right now they do require rather bulky lamps (Krypton Chloride), but last I checked there had been promising advancements in producing far-UVC LEDs [2]. Which should make installation and deployment of far-UVC both more practical and economical in the future.

Re: Self Sanitizing Door Handle
#59Aside, it’s obnoxious how many bathroom doors in public places like restaurants require you to pull the door handle to leave.
It should be pull to enter, push to leave so that you aren’t fouling your washed hands on the poopy door handle.
Even dumber is when they have those foot operated handles to exit. Why is it push to enter, pull to exit at all?

So that in an emergency your escape route can't be blocked. Also having doors swing out into corridors is bad practice as you're more likely to open it into someone walking past.
