Micro/nanorobots are widely applied to medical fields due to their small size and access to hard-to-reach human tissues. Medical micro/nanorobots can move, deform, rotate, or achieve other functions via different actuations. These actuations may come from sources inside (internal) or outside (external) human bodies. This review summarizes the actuation mechanisms, actuation-based functions, and possible biomedical applications of common actuations. The advantages and weaknesses of these internal and external actuations are discussed. Further success in medical MNRs is expected as actuation-related technologies progress shortly.

摘要

Micro/nanorobots are widely applied to medical fields due to their small size and access to hard-to-reach human tissues. Medical micro/nanorobots can move, deform, rotate, or achieve other functions via different actuations. These actuations may come from sources inside (internal) or outside (external) human bodies. This review summarizes the actuation mechanisms, actuation-based functions, and possible biomedical applications of common actuations. The advantages and weaknesses of these internal and external actuations are discussed. Further success in medical MNRs is expected as actuation-related technologies progress shortly.
