There are, IIRC, keyboards out there that're smooth ceramic plates, using induction fields for keypress detection and a short range RF or bluetooth connection to the host.
If you added magnetic induction power supply to those devices, you could have an easy-to-clean power pad and a keyboard that was a neatly rounded slab with no cables or protrusions. You could just swap them around every day and drop them all in a bucket of disinfectant ... or with some hardening even autoclave them.
Despite that, hospitals seem to keep on using keyboards that require cables trailing everywhere (dirty!) and that have uneven surfaces (very dirty!).
