English: Essentials for a microrobot to function in vivo
Design of an untethered microscopic mobile machine with medical interventional capabilities should assume an integrated approach where design 3D body shape, material composition, manufacturing technique, deployment strategy, actuation and control methods, imaging modality, permeation of biological barriers, and the execution of the prescribed medical tasks need to be considered altogether. Each of these essential aspects contains a special design consideration, which must be reflected at the physical design of the microrobot. The growing complexity and a big network of interactions among physical parameters necessitate an application-oriented design; the entire clinical scenario from the way of administration to the mechanism of action and to the disposal must be well-known and well-organized.
