Abstract

A new type of moisture-driven rotational motor is developed using a helical arrangement of graphene sheets along a graphene oxide fiber, which not only presents remarkable performance as a reversible rotary motor with a rotary speed of up to about 5200 revolutions per minute under humidity alternation, but also allows the construction of humidity switches and promising moisture-triggered electric generators.
