Precise manipulation of microparticles has received considerable attention for its great potential applications to clinical medicine. Among the existing manipulation techniques, the method of magnetic force based manipulation exhibits great advantages for its minimally-invasive feature and insensitivity to biological substance, making it ideally suitable to(More)
This paper presents the design of a magnetic micromanipulation system for wireless control of a single magnetic bead. Six orthogonally aligned electromagnetic coils were used to generate the magnetic fields for the manipulation and modeling equations were developed to evaluate the required inputs for each coil for precise closed-loop control of the magnetic(More)
Electromagnetically actuated microparticles can be widely applied in the field of biomedicine, for its advantages of minimally invasive feature and approachability to complex microenvironments. In this paper, we propose a robust feedback control approach for precise 3D manipulation of a microparticle actuated by a self-constructed electromagnetic coil(More)
This paper presents the design and fabrication of a magnetic microrobot transcporter with porous spherical structure produced by 3D laser lithography. The microrobots are coated with nickel (Ni) and titanium (Ti) for magnetic actuation and biocompatibility, respectively. A series of characterization experiments is conducted to show that Ni coating enables(More)
