An international team of scientists headed by the University of Bonn has developed a novel type of nanomotor. It is driven by a clever mechanism and can perform pulsing movements. The researchers are now planning to fit it with a coupling and install it as a drive in complex machines. Their findings have now appeared in the journal Nature Nanotechnology. 

This novel type of motor is similar to a hand grip trainer that strengthens your grip when used regularly. However, the motor is around one million times smaller. Two handles are connected by a spring in a V-shaped structure. ...
