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“.
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
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.
