Abstract:Motility is achieved by energy conversion. In nature, motility is linked to stimuli‐responsive behavior occurring at the nanometer length scale, the operation of molecular machines. Nature's molecular machines all comprise of actuator material; where an actuator is a device that converts one source of energy into another to generate a force or motion. Such stimuli‐responsive materials are often referred to as
smart
because they respond to changes in their surrounding environment. The ab… Show more
