This research aims to develop origami-inspired microrobots using shape memory alloys (SMA) for advanced biomedical applications, such as minimally invasive surgery, targeted drug delivery, and in-situ diagnostics. Drawing inspiration from the principles of origami and the SMA microactuation effect, these microrobots are composed of interconnected, programmable microscale tiles capable of dynamically folding into complex three-dimensional shapes. This capability enables the creation of highly adaptive systems that respond to changing environmental conditions and perform precise tasks at the microscale with high precision and efficiency. The project focuses on pioneering methodologies for the design, fabrication, and control of these microrobots.

We are seeking an enthusiastic and talented PhD candidate (f/m/d) to contribute to this groundbreaking project at the intersection of robotics, biomedical engineering, and materials science. The successful candidate will work on designing programmable microrobot systems with reconfigurable 3D shapes, leveraging advanced materials and clean room microfabrication techniques. These microrobots will provide reversible and precise folding and unfolding mechanisms, opening the door to transformative applications in minimally invasive surgery, targeted drug delivery, and diagnostics.
