He is the editor-in-chief of Progress in Biomedical Engineering and Journal of Micro-Bio Robotics and associate editor in Science Advances and Extreme Mechanics Letters journals.

 

Soft-bodied Small-scale Mobile Robots

Untethered small-scale mobile robots have the potential to revolutionize healthcare, since they have the unique capability of accessing, operating and possibly staying inside hard and currently not possible to reach small spaces inside the human body non-invasively. On the other hand, soft-bodied robots have unique capabilities with compared to their fully rigid counterparts, such as shape changing and programming, physical adaptation, safe operation, and multifunctionality. Using such unique capabilities of soft robots for medical applications, we propose new miniature soft medical robots that are actuated using external magnetic fields. We first developed a shape-programming methodology for 2D magneto-elastic materials, and used such materials to create magnetic soft millirobots inspired by soft-bodied organisms, such as spermatozoids, caterpillars, and jellyfishes. A magneto-elastic sheet-shaped soft robot is demonstrated to be able to have seven or more locomotion modalities to be able to navigate in complex environments, such as inside the human body. Next, a baby jellyfish-inspired magneto-elastic milliswimmer is shown to realize multiple functionalities by producing diverse controlled fluidic flows around its body. Then, an array of cilia-inspired magneto-elastic cilia is developed to generate metachronal waves for efficient biofluid pumping and fluidic object manipulation. Also, various 3D metastructures-based soft robots with specific medical functionalities are introduced under ultrasound type of medical imaging modalities. Finally, liquid crystal elastomer type of stimuli-responsive materials are integrated with magneto-elastic composites towards self-sensing and self-adapting physically intelligent robots at the small scale.
