Small-scale Magnetically Actuated Robotic Tools for Biomedical Applications

Tuesday, February 1, 2022 9:00 am - 10:15 am EST (GMT -05:00)

Research seminar 

Small scale robots have the potential to offer many unique applications for minimally invasive surgery, sensing and drug delivery in healthcare as well as more generally for microfactories and as scientific tools. They are precise end-effectors that can manipulate objects with a high degree of accuracy. Many surgical and on-chip tasks can be performed by manipulating these robots in their dedicated environments. Therefore, these robots are an attractive research area because of their ability to maneuver inside small and constrained environments and perform tasks that were previously considered infeasible. These robots enable us to make surgery minimally invasive as they can remotely navigate their way to a target site through tortuous paths and perform interventional tasks. Because these robots are too small for electronics and on-board power, they are often actuated remotely using magnetic fields as these field can penetrate most environments and are relatively safe for biological organisms. This makes them an ideal tool to use inside the human body and for on-chip applications with cells. Soft continuum robots as well as moving microrobots actuated using magnetic fields will be shown along with the progress these technologies have made towards different medical applications.
