Resonant Acoustic Microrobots
The newly designed microrobot consists of a cavity at the center of its body within the polymer matrix. The microcavity supports an air-bubble trap, which enables propulsion in an acoustic field.
Ultrasound is regarded as a safe, non-invasive, and relatively inexpensive procedure, and is widely used in clinical diagnostics and therapeutics. This project has the potential to leverage ultrasound to open up a new and exciting area relevant to fields such as targeted drug delivery and micromanipulation technologies. Micro-robotics capable of controlled motion at the microscale could open up exciting opportunities in the manipulation of particles, precise assembly of materials, targeted drug delivery, and non-invasive microsurgery. The soft microswimmer contains one or more microcavities at the center of its body. The microcavity supports an air bubble trap, which, when acoustically activated, produces a bubble oscillation that results in propulsion. The nonlinear response during bubble activation enables acoustic energy to be focused to high densities, while the resonance behavior allows bubbles of different sizes to be selectively actuated by varying the sound wave frequency. The successful implementation of individually-addressable, bubble-based, resonant microrobots will bring about a paradigm shift in targeted-drug delivery, collective behavior, and micro-assembly.

In this project, we aim to
- Design and develop a 3D microrobot with different size microbubbles
- Characterize it using high-speed imaging systems and custom-built particle tracking technology.
- Investigate propulsion in physiological relevant flow profiles
- Characterize the scaling behavior of the microrobot’s motion
- Collaborative work (if time permits)
