A Tumbling Magnetic Microrobot System for Biomedical Applications

A Micro-scale Magnetic Tumbling Microrobot

This paper presents a magnetic tumbling microrobot design at the micro-scale. The microrobot has a dumbbell shape whose largest dimension is about 400 μm. When subjected to an exterior predefined magnetic field, the magnetic microagent performs a tumbling motion driven by the interacting magnetic forces and momentums. The magnetic field providing driven force is generated by a coil system consi...

Magnetic Particles for Biomedical Applications

This chapter discusses applications of magnetic materials in bioengineering and medicine [1–8]. Magnetism and magnetic materials have been used for many decades in many modern medical applications, and several new applications are being developed in part because of the availability of superior electromagnets, superconducting magnets and permanent magnets [9–12]. Advances in the synthesis and ch...

Development of Biomedical Microrobot for Intravascular Therapy

Recently, coronary artery disease such as angina pectoris and myocardial infarction has become the major causes of death. As a method of medical treatment for the disease, the pharmacological approaches and the surgical operations are executed. Especially, percutaneous coronary intervention (PCI) using catheters are the mostly preferred treatment for coronary artery diseases. The PCI technologi...

Magnetic microrobot and its application in a microfluidic system

This paper researches the design and control method of a microrobot in a microfluidic system by electromagnetic field. The microrobot can move along the microchannel to a required position, and by changing the magnetic torque, the microrobot can also rotate in the microfluidic chip. As an application of the microrobot, it is used as a mobile micromixer to mix two solutions in the microfluidic c...
