An interesting take. There is also brass and coppers that self-sanitize, albeit more slowly: <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11279221/" rel="nofollow">https://pmc.ncbi.nlm.nih.gov/articles/PMC11279221/</a>
This feels like a thoughtful engineering project and a strong competition entry
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.
What about bathroom doors that are touched constantly?
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.<p>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
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?

Or, you know, just use brass:<p><a href="https://en.wikipedia.org/wiki/Antimicrobial_copper-alloy_touch_surfaces" rel="nofollow">https://en.wikipedia.org/wiki/Antimicrobial_copper-alloy_tou...</a>
Why not just use brass? Seems like a solution in search of a problem.
