Post-doc – Ultrasound powered microswimmers: mass fabrication and controlled direction
Even under medium amplitude acoustic driving, nonlinear effects appear around vibrating bubbles, generating strong steady flows called acoustic streaming. We propose to use these flows in order to achieve propulsion of small scale, and to generate a new class of micro-swimmers. Their application is to behave as carriers, such as drug carriers, activated at a distance, or to be active tracers that enhance mixing. Microswimmers are mechanical analogues to RFID devices (where electromagnetic vibration is converted into current): here sound is converted into motion at small scales.
