Something like this might be developed into a keyboard for the treatment rooms. It would take up very little space be easy to get out of the way and could possibly be made so that you could wipe and disinfect.
A very thin keyboard that uses shape-changing polymers to replicate the feel and sound of chunky, clicking buttons could be in laptops and ultrabooks next year. Strategic Polymers Sciences, the San Francisco-based company that developed the keyboard, is working on transparent coatings that would enable this feature in touch screens.
This also might be a nice option for patients to fill forms with a tablet. The on screen keyboards are a bit awkward in many cases.
