Abstract:Wireless miniature medical robots have the unique capability of navigating, operating and staying inside hard- or impossible-to-reach tight spaces inside our body. This talk reports on various recent milli/microscale wireless miniature medical robots that could achieve various minimally invasive medical functions, such as targeted active drug delivery, neural stimulation, clot opening, liquid biopsy, tissue drilling, biofluid pumping, and hyperthermia. Due to miniaturization limitations on on-board actuation, powering, sensing, computing and communication, new methods need to be introduced in creating and controlling such robots. Moreover, they need to be tracked under medical imaging modalities, such as ultrasound, fluoroscopy, photoacoustic imaging and MRI, for their precise and safe operation and control. 3D microprinting-based fabrication methods and multifunctional soft composites are proposed to create novel medical milli/microrobots. External physical forces, such as magnetic fields, acoustic waves and light, are used to actuate and steer such tiny robots wirelessly as a single robot or robot collectives/swarms. These robots are aimed to save lives of more people by curing diseases not possible or hard to cure at the moment and decrease the side effects and invasiveness of disease treatments significantly in the future.
