(A) Magnetic guidance, Visualization of MagRobots in vivo via various medical imaging modalities. Using external magnetic fields, micro- and nanorobots can be propelled with magnetic gradient forces or magnetic torque through rotating fields (Pawashe et al., 2009; Chen et al., 2018).

Navigation, release, anchoring, and biocompatibility of these small-scale devices are further open challenges that require proof-of-concept studies and in vivo verification. For the minimal-invasive percutaneous trial, SCS placement is usually done when the patient is awake in order to receive patient feedback in response to stimulation when determining the optimal lead location. 2016 The Authors. 2018 American Chemical Society. The remaining surgery would proceed in the traditional sense. However, both of these fuels, H 2 O 2 and N 2 H 4, are cytotoxic. Alternatively, a simple variable stiffness catheter design can be based on current technology, where the stiffness of the stimulation lead is controlled by the degree of insertion of the guidewire (Schulder, 2003).

Deviations from the trajectory could either be corrected by turning and angling the magnetic tip in the direction of the trajectory or by the application of lateral gradient fields to counter lateral tissue forces directly if they are low magnitude.

Copyright The use of MNS allows correction of the trajectory in real time during advancement of the electrode and offers the surgeon a yet unidentified degree of flexibility to adjust the surgical probe to follow the desired trajectory. For magnetically driven micro/nanorobots, whether in vitro or in vivo, MRI is an effective tool for tracking the robot's position. The use of rotating fields may manage these challenges as micro- or nanorobots could overcome boundary forces while rolling on the surface (Figure 2E) or exhibit a surface walker locomotion behavior (Peyer et al., 2013). Microrobotic swarms have attracted extensive attentions due to their potential in medical and bioengineering applications. Hu X., Chen A., Luo Y., Zhang C., Zhang E. (2018).
