  • Apparatus and method for monitoring a sedimentation parameter in a fluid medium sample
    Patent number: 10054531
    Abstract: There is provided a method of measuring a sedimentation parameter of suspensions or precipitants in a fluid medium sample, said method compromising providing at least one micro-cantilever sensor, said micro-cantilever sensor comprising at least two materials having different coefficients of thermal expansion, and having a heater and piezo-resistive sensor integrated therein, pulsing the heater with one or more electrical pulses to induce heat generation in the micro-cantilever, sampling the output of the integrated piezo-resistive sensor to characterize a response of the micro-cantilever during sedimentation in the fluid medium sample, and determining a value of the sedimentation parameter from the characterized response. There is also provided an apparatus arranged to carry out the method.
    Type: Grant

    Date of Patent: August 21, 2018
    Assignee: Microvisk Limited
    Inventors: Richard John Dunn, Lois Bello Fernandez De Sanmamed, Robert Henry Ibbotson, Vladislav Djakov
  • APPARATUS AND METHOD FOR MONITORING A SEDIMENTATION PARAMETER IN A FLUID MEDIUM SAMPLE

    Abstract: There is provided a method of measuring a sedimentation parameter of suspensions or precipitants in a fluid medium sample, said method compromising providing at least one micro-cantilever sensor, said micro-cantilever sensor comprising at least two materials having different coefficients of thermal expansion, and having a heater and piezo-resistive sensor integrated therein, pulsing the heater with one or more electrical pulses to induce heat generation in the micro-cantilever, sampling the output of the integrated piezo-resistive sensor to characterise a response of the micro-cantilever during sedimentation in the fluid medium sample, and determining a value of the sedimentation parameter from the characterised response. There is also provided an apparatus arranged to carry out the method.
