Miniature Mobile Robots for Biomedical Applications 

 Untethered miniature mobile robots have the unique capability of accessing to hard to reach, tight areas inside the human body non-invasively. In this talk, design, fabrication, and control of different size-scale miniature medical robots are presented. First, pill-size, swallowable untethered soft capsule robots are proposed to enable minimally invasive medical diagnosis and therapeutic operations inside stomach. Such minimally invasive soft capsule robots can actively image, release drugs, and conduct microbiopsy. Next, going down to sub-millimeter scale, two alternative approaches are explored to create micron-scale mobile robots toward biomedical applications. First, biological cells, e.g. bacteria, attached to the surface of synthetic particles or other materials are used as on-board microactuators and microsensors in physiological fluids. Bacteria-driven biohybrid microswimmers are steered using chemical and pH gradients in the environment and remote magnetic fields for in vitro targeted active cargo (drug and imaging agent) delivery. As the second approach, external actuation of miniature magnetic robots using remote magnetic fields in enclosed spaces is demonstrated. Novel soft and rigid magnetic robots are proposed to manipulate live cells and microgels with embedded cells for bioengineering applications. Such magnetic milli/micro-robots will be steered inside an MRI system in the near future for different medical applications. Moreover, magnetic micro-robots will be remotely stimulated to create local electrical or thermal effects to control the neural activity inside brain.
