Micro motors are functional extensions and useful supplements to traditional motor systems,with potential applications in wastewater treatment,environmental monitoring and remediation,targeted surgery and drug delivery.In the fluid environment,high efficiency driving performance is an important challenge for micro motors.Based on theories and research practices,bionic helical structures have been commonly chosen as microdriving strategies for motors,and many new advances have been made.In this review,to achieve a wide vision of recent progress on helical micromotors,some aspects are discussed,including the driving theory,preparation of micro-helical structures,specific mechanism of helical-robot moves and diverse applications of helical-robots.Finally,the unresolved questions of helical micromotors are given and the direction of further study are discussed.
