IMT 02-18 / Master Thesis: An array of Impulse Electro-magnetic Micro-actuator

Karlsruhe Institute of Technology (KIT)

Karlsruhe, Germany

Work group:

Institute of Microstructure Technology (IMT)



Area of research:

Diploma & Master Thesis



Job description:

In the framework of the master thesis, the student will be involved in the theoretical and experimental study of the mechanical interaction between a solid micro-object having different shapes (sphere, disk and square) and an array of micro-coils, which are fitted by impulse currents.


Main objectives are:


Designing, modelling and simulation of magnetic gradient generated by micro-coil (considering geometry and shape effect of the coils);Theoretical and experimental study electro-mechanical interactions between the local magnetic gradient generated by micro-coils and micro-objects fabricated from magnetic and conducting material;Fabrication of the prototype

The topic of the master thesis is the continuation of research activities of our group toward the study of micro-machined contactless suspensions and their applications in optics, sensors and actuators (please see a video below).

Field of study: Mechanical engineering, Physics


Contract Duration:


6 months
