For magnetically driven micro/nanorobots, whether in vitro or in vivo, MRI is an effective tool for tracking the robot's position. Micro- or nanorobots are small-scale devices designed to perform minimally-invasive interventions and are powered by external power sources (Colberg et al., 2014; Zeeshan et al., 2014; Rao et al., 2015; Chen et al., 2017a; Soto et al., 2021).

By modulation of the external magnetic field input, the electrical field amplitude and shape could be adjusted as desired (Nan et al., 2008; Armin et al., 2012). Electrode migration occurs in 1322% of SCS patients (Taccola et al., 2020), is more common with the less invasive percutaneous technique, and has been reported as the most frequent reason for repeat surgery (Turner et al., 2004), resulting in increased risk for the patient and additional operative time and cost.
