Our research group focuses on creating new devices and microsystems for biomedical applications. The aim is to integrate actuation, sensing, and computation to advance surgical procedures.
One research focus involves the development of micro-/nano-devices that can actively propel and be wirelessly controlled through the human body – micro-/nano-robots – for the next-generation surgical robots, which have various medical applications including drug delivery, in vivo sensing and stimulation.
The challenge is to overcome the natural biological barriers, and one solution is to be very small in size – smaller than the nano-sized pores of tissues. The team succeeded in steering nanorobots with only 500 nm in diameter through the vitreous tissue of an eye for minimally-invasive drug delivery, which had never been achieved before.
Another research focus is to develop a new kind of cyber-physical organ phantom based on three-dimensional (3D) printing and augmented reality (AR). The physical part of the phantom provides high-fidelity anatomy made from biomimetic soft materials that allow surgery to be performed, bleeding and realistic multi-modality medical imaging.
The cyber part of the phantom presents an interface to visual and sensory data, which provides medical big data that are otherwise impossible to be recorded on a real human organ. The group has ongoing collaborations with leading hospitals in Germany to integrate the technologies for surgical training and surgical robot testing.
