摘 要：Practical implementation of minimally invasive biomedical applications has been a long-sought goal for *** this field,most previous studies only demonstrate microrobots with locomotion ability or performing a single task,unable to be functionalized ***,we propose a biocompatible shape memory alloy helical microrobot with regulative structure transformation,making it possible to adjust its motion behavior and mechanical properties ***,towards vascular occlusion problem,these microrobots reveal a fundamental solution strategy in the mechanical capability using shape memory *** shape-transformable microrobots can not only manipulate thrust and torque by structure to enhance the unclogging efficiency as a microdriler but also utilize the high work energy to apply the expandable helical tail as a selfpropulsive *** strategy takes advantage of untethered manipulation to operate microsurgery without unnecessary *** study opens a route to functionalize microrobots via accurate tuning in structures,motions,and mechanical properties.
