Graphene can be used to create artificial muscles?

Researchers managed to fabricate electrochemical actuators based on flexible graphene paper. These kinds of devices can convert electrical energy into mechanical energy through stretching or contraction, behaving like artificial muscles. This has all sorts of potential applications - in healthcare and nanotechnology...

The graphene-paper actuators lengthen in response to applied voltage, due to changes in the carboncarbon bond length. The team managed to increase the response by magnetizing the paper using Fe3O4 nanoparticles.
