Magnetic field concentration using ferromagnetic material to propel a wireless power transfer based micro-robot

“…[4][5][6][7] One reported that oxygen bubbles produced by the chemical reaction were enough to move the micro-robot. However, while micro-robots propelled by chemical reactions have advantages with respect to miniaturization, being in the µm size range, their practical use is limited since they stop running when the chemical reaction is complete.…”

Photocatalytically Powered Matchlike Nanomotor for Light‐Guided Active SERS Sensing

“…Apart from photothermal mechanisms, [5] there has been substantial progress in the development of photocatalytically powered MNMs. [7] Researchers then achieved tunable propulsion wavelengths by using black TiO 2 [8] ,s ilicon nanowire motors, [9] or combining light-sensitive dyes with the motors.
