Investigation of micro/nano motors based on renewable energy sources

Abstract

Nano/micro motors are machines specially designed to accomplish special functions as they drive themselves with respect to particular stimuli. Design construction of such synthetic motors experience heavy challenge due to their minute structural complexity. However, design of micro/nanomotors get wider attraction in recent world because of their minute structural construction. Many of them requires electrical or chemical propulsion for their mechanical mobility. But, propulsion by renewable energy sources like solar, wind and light/sound energy are become trending techniques in recent world. Such kind of renewable energy based nano/micro motor propulsion does not require any physical attachment with motor design also leads to reduction in waste products with easy control. This review investigates the highlights of various studies dealing with renewable energy sources based micro/nano motor design. Also, this review summarizes different propulsion mechanisms along with application of micro/nano motors in different fields.
