  Muscle Designed for Shape-Changing Robots
 
  Cornell University physicists built the "muscle" for an electricity-conducting, environment-sensing, shape-changing machine the size of a human cell.

The machines move using a motor called a bimorph. A bimorph is an assembly of two materials - in this case, graphene and glass - that bends when driven by a stimulus like heat, a chemical reaction or an applied voltage. The shape change happens because, in the case of heat, two materials with different thermal responses expand by different amounts over the same temperature change.
