One of the most promising application directions for magnetic shape memory alloys are microfluidic pumps and related devices. The topic studied in this project, i.e. control of twinned structure, or ferroelastic domain engineering, made by a surface modification, and consequent defined mechanical (muscle-like) action of the material, are prerequisites for the micropump operation. The example figure illustrating the process is shown below:

Thank you Gabriel for a good job!
Gabriel Bruno Parreira, a student from the Faculty of Mechanical Engineering of the Czech Technical University, spent one year in our team in order to reveal the specific problems related to the control of twinned structure and design of magnetic shape memory micropumps.
