  • Multi-mode mechanical swimmer that acts as a rheometer
    Patent number: 12644812
    Abstract: 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 normal stress components ?1 and ?2, by observing motion of the robot in the fluid. The robot is preferably rotationally symmetric, but with a fore-aft head-tail asymmetry that enables propulsion in complex fluids when the head and tail are driven to rotate opposite each other about the rotational axis of symmetry.
    Type: Grant
    Filed: August 8, 2022
    Date of Patent: June 2, 2026
    Assignee: The Board of Trustees of the Leland Stanford Junior University
    Inventors: Eric S. G. Shaqfeh, Manu Prakash, Laurel Kroo, Jeremy Patrick Binagia
