Navigation with magnetic nanoparticles: magnetotactic bacteria and magnetic micro-robots
Physica Scripta, 2015Magnetotactic bacteria navigate in the magnetic field of the Earth by aligning and swimming along field lines with the help of special magnetic organelles called magnetosomes. These organelles contain magnetic nanoparticles and are organized into chain structures in cells.

Reliability of active robotic neuro-navigated transcranial magnetic stimulation motor maps
Experimental Brain Research, 2022Transcranial magnetic stimulation (TMS) motor mapping is a safe, non-invasive method used to study corticomotor organization and intervention-induced plasticity. Reliability of resting maps is well established, but understudied for active maps and unestablished for active maps obtained using robotic TMS techniques.

Water-Immiscible Coacervate as a Liquid Magnetic Robot for Intravascular Navigation
Journal of the American Chemical Society, 2023Developing magnetic ultrasoft robots to navigate through extraordinarily narrow and confined spaces like capillaries in vivo requires synthesizing materials with excessive deformability, responsive actuation, and rapid adaptability, which are difficult to achieve with the current soft polymeric materials, such as elastomers and hydrogels.

Magnetic controlled navigation system for endoscopic micro robot
2009 IEEE 3rd International Conference on Nano/Molecular Medicine and Engineering, 2009A novel magnetic controlled navigation system is proposed for controlling endoscopic micro robot's locomotion and location in the gastrointestinal tract. The proposed approach exploits permanent magnet and mechanical movement to generate quasi-static magnetic field instead of AC alternating magnetic field, and thus can be applied to the noninvasive ...

Magnetic and robotic navigation for catheter ablation
Journal of Interventional Cardiac Electrophysiology, 2008Catheter ablation has become the treatment of choice to cure various arrhythmias in the last decades. The newest advancement of this general concept is made on the navigation ability using remote-controlled ablation catheters. This review summarizes the concept of the two currently available systems, followed by a critical review of the published ...

Dynamic tracking effect of a magnetic navigated dual hemisphere capsule robot
Robotica, 2022AbstractFor diagnostic and therapeutic applications in spacious spots of the gastrointestinal (GI) tract, the single rigid body capsule clinically applied is difficult to realize the fix-point posture adjustment function manipulated by the external permanent magnet system using the static balance control because the posture alignment and the locomotion

IEEE Transactions on Industrial Electronics, 2017
We propose a novel magnetic navigation system (MNS) with the resonant effect of an RLC circuit to generate large magnetic field in high frequency. The variable capacitors of the proposed MNS make it possible not only to change the resonant frequency of the RLC circuit, but also to maximize the output current without phase delay at variable resonant
