Independent Group Leader Dr. Tian Qiu

Advances in minimally invasive procedures and artificial intelligence (AI) are increasingly impacting medical care. Future developments depend on a close interplay between hardware and its integration with big data and AI. We are interested in developing tools that collect large amounts of data and to learn from the data to understand the underlying principles. With close collaborations with medics, the Cyber Valley research group at the University of Stuttgart focuses on the two following aspects:

Micro-/Nano-Robotics for Biomedical Applications

The recent technology advancements of micro-/nano-system engineering and robotics opens up new possibilities for the next-generation surgical robots – wireless micro-/nano-robots, which can be controlled navigate in the human body and may lead to various medical applications including drug delivery, in vivo sensing and stimulation. The team succeeded in developing the first soft microrobot that can swim in biological non-Newtonian fluids by reciprocal motion, and the first nanorobots that can penetrate real tissue – the vitreous of the porcine eye.
