Sufficient flexibility of the catheter tip is necessary to provide steering freedom and after removal of the magnetic field, stress-relaxation (micro-shattering of the electrode tip) should be avoided (Jonathan and Groen, 2005; Petruska et al., 2016). Dive into the research topics of 'Magnetically Driven Micro and Nanorobots'. Navigation, release, anchoring, and biocompatibility of these small-scale devices are further open challenges that require proof-of-concept studies and in vivo verification.

Hence, buckling and alignment of the tip are major problems that have to be considered, and methods need to be developed to steer the magnetic SCS lead precisely despite unpredictable anatomical obstacles.

Copyright 2016 American Although a few biocompatible magnetostrictive and piezoelectric materials exist (Wang et al., 2010; Rajabi et al., 2015; Ribeiro et al., 2018), the compatibility of these materials in the spinal epidural space or subarachnoid space needs to be investigated in future research as literature suggests that different tissue types show different cellular responses (Duliska-Litewka et al., 2019). Finally, infection related to SCS occurs in ~5% of the cases (Bendersky and Yampolsky, 2014). Manipulation and navigation of micro and nanoswimmers in different fluid environments can be achieved by chemicals, external fields, or even motile cells. In some cases, a repeat surgery to adjust the electrode lead(s) is needed to determine ideal lead placement. For magnetically driven micro/nanorobots, whether in vitro or in vivo, MRI is an effective tool for tracking the robot's position. Chesnitskiy AV, Gayduk AE, Seleznev VA, Prinz VY.

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). Actuation mechanisms of flagella-inspired MagRobots (i.e., corkscrew-like motion and traveling-wave locomotion/ciliary stroke motion) and surface walkers (i.e., surface-assisted motion), applications of magnetic fields in other propulsion approaches, and magnetic stimulation of micro/nanorobots beyond motion are provided followed by fabrication techniques for (quasi-)spherical, helical, flexible, wire-like, and biohybrid MagRobots.
