  • Device and method for measuring the rheological properties of a yield stress fluid
    Patent number: 9116092
    Abstract: A device and a method are provided for measuring the yield stress of a fluid. The device includes a container for receiving the fluid therein and an auger having a shaft extending along an axis and a helical flange extending radially about the shaft. The auger is movable in the fluid between a first position and a second position. A sensor is operatively connected to the auger. The sensor measures a force on the auger as the auger moves from the first position to the second position. A linkage is interconnected to the sensor. The linkage translates motion to the auger.

  • Magnetorheological fluid device
    Patent number: 7306083
    Abstract: A device employing a magneto rheological (MR) fluid in combination with a stator and a rotor is disclosed, where the stator includes a magnetic field generator. The rotor has a rotational axis and a rotational degree of freedom with respect to the stator. The stator and rotor define an annular space therebetween and are coupled via the MR fluid disposed within the annular space, and the magnetic field generator is in field communication with the MR fluid at the annular space. The device includes a means for promoting the formation of stationary stripes of MR fluid within the annular space in response to rotation of the rotor.

  • Protein enhanced electrorheological fluids
    Patent number: 5435931
    Abstract: An enhanced ER fluid is disclosed. Polypeptides such as proteins are added to ER fluids. The ER response, particularly increased viscosity in response to an electric potential difference applied to the fluid, is enhanced.
