Improved rheometry is provided using an autonomous swimming robot that can be driven at least in an angular velocity mode and in a torque mode. The resulting improved capability can enable measurement of multiple rheological parameters, such as both …
We present a self-propelled axisymmetric low-Reynolds-number swimmer (force- and torque-free) that, while unable to swim in a Newtonian fluid, propels itself in a non-Newtonian fluid as a result of fluid elasticity. The propulsion gait is pure …
