Master Thesis:
Thermal Training Optimization of Shape Memory Folding Actuators

Organisationseinheit:

Institut für Mikrostrukturtechnik (IMT)

Ihre Aufgaben:

Thermal heat treatment with precise heating current and accurate mechanical clamping is required to set the desired shape of the folding microactuators.

Thereby, the annealing power depends strongly on the geometric dimensions and stress state of the folding hinges.

As the complexity of the structures increases, a flexible electrical and mechanical setup is required for the controlled training of the individual folding actuators.

Experiments have shown that the change in electrical resistance of the SMA can provide information about the transformation processes in the material.

For the shape-setting of SMA actuators, they must be heated to the region of crystallization of the amorphous material or recrystallization of a pre-annealed material so that a new memory shape is imprinted.

This work will contain the design and fabrication of a training test bench for the controlled heat treatment of pre-annealed and amorphous SMA folding actuators.

Here, the resistance is to be measured in real-time via a 4-point measurement and the supplied current is to be controlled according to the resistance variation.

The student thesis can be written in German or English.
