Ihre Aufgaben
As part of the DFG KOMMMA program, the SMD group at IMT is conducting research on novel concepts of origami-inspired cooperating foldable shape memory alloy (SMA) microactuators called "Re-Programmable Micro-Matter". Thus, complex, and adaptive 3D microstructures can be folded to enable promising future applications in minimal-invasive surgery, micro-assembly, and micro-robotics.
A large folding angle is critical for high configuration complexity and reliable latching of the structure. Since the folding angle is limited in conventional bidirectional SMA actuator design, in this work a novel SMA folding actuator with a bistable mechanical folding support will be developed and investigated. First, a mechanical arrangement consisting of a SMA snapping mechanism and a SMA folding actuator will be designed for Joule heating.
Subsequently, these components will be fabricated using state-of-the-art microfabrication technology and 3D printing, and the SMA folding actuator will be shape-set. Finally, a characterization setup will be built to determine the mechanical and electrical performance of the novel actuator.
The thesis can be written in German or English.
