Small Scale Thermo-Magnetic Generator Based on Shape Memory Alloys

Small Scale Thermo-Magnetic Generator Based on Shape Memory Alloys
Type:Master Thesis
Supervisor:

Prof. Dr. Manfred Kohl

Field of Study:

Mechanical engineering, electrical engineering, physics

Links:Smart Materials and Devices

Job description

New concepts are being developed that use magnetic shape memory alloys to convert waste heat into electrical energy. One example are freely movable beam cantilevers showing a large temperature-dependent change of magnetization. By putting in contact to a heat source, the cantilevers start to self-oscillate and to generate electrical energy. Thus, small temperature differences in the environment can be used to operate, e.g., wireless sensor networks for the „Internet of Things“.

Your tasks:

This works aims at new design variants with optimized thermo-magnetic performance and power output. The Master thesis includes the following topics:

  • Design optimization based on available simulation models
  • Rapid prototyping (3D printing, laser cutting)
  • Characterization of demonstrator variants (thermo-mechanical, electrical properties)
  • Implementation of a power management system

 

Starting date: On appointment

Contract duration: Limited to 4-6 months

Qualification:
We are looking for ambitious, creative and self-motivated individuals, who like to work within a multidisciplinary and international team. Basic knowledge in materials science, MATLAB programming, CAD and FEM simulation (Comsol) is advantageous.
