Researches on the biomedical wireless microrobot are being actively carried out. In particular, compared with conventional catheter intervention, the wireless locomotive microrobot using an electromagnetic navigation system (ENS) can have many advantages in ischemic heart disease therapy. The ENSs generally use a uniform magnetic field and gradient magnetic field for the actuation of microrobots....
In this paper, we proposed an intravascular therapeutic microrobot using an electromagnetic actuation (EMA) system with bi-plane X-ray imaging device. The proposed EMA system consists of Helmholtz-Maxwell coils, uniform-gradient saddle coils. The Helmholtz-Maxwell coils are located along y-axis, and uniform-gradient saddle coils are located perpendicular to y-axis. In order to align the microrobot...
