Magnetic Actuation Methods in Bio/Soft Robotics

Abstract

In recent years, magnetism has gained an enormous amount of interest among researchers for actuating different sizes and types of bio/soft robots, which can be via an electromagnetic‐coil system, or a system of moving permanent magnets. Different actuation strategies are used in robots with magnetic actuation having a number of advantages in possible realization of microscale robots such as bioinspired microrobots, tetherless microrobots, cellular microrobots, or even normal size soft robots such as electromagnetic soft robots and medical robots. This review provides a summary of recent research in magnetically actuated bio/soft robots, discussing fabrication processes and actuation methods together with relevant applications in biomedical area and discusses future prospects of this way of actuation for possible improvements in performance of different types of bio/soft robots.

Biocompatible Nanomaterials as an Emerging Technology in Reproductive Health; a Focus on the Male

“…In this research, magnetic IONPs were electrostatically attached to a cellular template so that the resultant microrobot could then be manipulated using a magnetic field. The researchers envisage that this technology may be used to activate motility in non-motile spermatozoa ( Khalil et al, 2020 ; Magdanz et al, 2020 , 2021 ), and be useful for the guided delivery of exogenous DNA or chemotherapeutics ( Ebrahimi et al, 2020 ).…”

Artificial Intelligence of Things (AIoT) Enabled Virtual Shop Applications Using Self‐Powered Sensor Enhanced Soft Robotic Manipulator

“…While for the anthropomorphic robots in real space, the realization of the human perception system is essential to provide feedback information precisely. Compared with the rigid robotic manipulators widely used in various industries, soft robots [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ] made by flexible materials, e.g., thermoplastic polyurethanes (TPU), are more suitable to fabricate the humanoid robotic finger due to the flexibility, lightweight, multidegree of freedom, and excellent conformability, etc. [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ] Generally, the low‐cost solution of a soft robotic system with marginal sensing functions is desired for the massive deployment of the humanoid robotics.…”

Functionalization of Biotinylated Polyethylene Glycol on Live Magnetotactic Bacteria Carriers for Improved Stealth Properties

“…To address this issue, Magnetospirillum magneticum AMB-1 magnetotactic bacteria (MTB) could be used as an alternative drug delivery agent [23]. These bacteria have all of the basic requisite components, namely, a sensory system that helps them to sense the oxic-anoxic interface (OAI)-a hotspot for their adaptation-a control system by which they navigate using the Earth's magnetic field and, lastly, an actuation system that helps them in controlling their motility, which makes them an excellent drug delivery agent [24]. MTB is known to be a self-propelled organism, and its movement can be precisely controlled by an external magnetic field with the help of magnetosomes composed of superparamagnetic Fe3O4 or Fe2O3 nanoparticles [25].…”
