|English: Illustration of the Casimir effect. (Photo credit: Wikipedia)|
One of the strangest effects to arise from the quantum nature of the universe is the Casimir force. This pushes two parallel conducting plates together when they are just a few dozen nanometres apart. ..... So instead of being hindered by uncontrollable Casimir forces, the next generation of microelectromechanical devices should be able to exploit them, perhaps to make stictionless bearings, springs and even actuators.
