![]() This type for MRI system offers both real-time image acquisition and three-dimensional (3D) propulsion of a microrobot. 12 A microrobot driven by the electromagnetic field of a magnetic resonance imaging (MRI) system has been actively studied by Martel et al. 8,9 Since a microrobot is driven wirelessly by an electromagnetic field, it can be applied in encephalop- athy, 10 retinal therapy, 11 and vascular treatment. Recently, many researchers have studied microrobots using EMA systems. 3–7 The electromagnetic force produced by the EMA system can move the microrobot composed of paramagnetic or ferromagnetic materials to a desired position. increased incidences of cardiovascular diseases from the growing aging society and bad eating habits, 1,2 microrobots based on electromagnetic actuation (EMA) systems have been proposed for cardiovascular treatment. ![]()
