Building at the molecular scale you can achieve extremely low friction coefficients in the moving parts. Inertia also gets extremely low, and material strengths tend toward their theoretical values.
Of course electronics aren't standing still, but resistance tends to get harder to deal with as feature sizes decrease.
- PeterisP 5y agoWhat I've always wondered is that wouldn't very tiny molecular mechanisms get problems with "accidental welding" since a part could be permanently destroyed by a few molecular bonds forming or breaking and (IMHO - this is my guess/assumption) such events would be likely at e.g. room temperature.
- db48x 5y agoUnless designed well, yes. Parts that move relative to each other need to be designed so that unwanted bonds are unlikely to form. This generally means designing them so that unwanted bonds are less energetically favorable than the bonds they start out with. Of course, as temperature rises, the chance of breaking existing bonds rises, as does the chance of forming new unwanted bonds.
