  • 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.

  • Patent number: 9551702
    Abstract: There is provided a method of monitoring one or more specified reactions in a fluid medium sample using a thermal signature, comprising 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, calibrating the at least one micro-cantilever response to thermal changes to form a calibrated micro-cantilever response characteristic, starting the specified reaction in the fluid medium sample, 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 the specified reaction in the fluid medium, and subtracting the calibrated micro-cantilever response characteristic from the sampled output to determine a characteristic of the one or more specified reactions in the fluid medium sample.

  • Patent number: 8881578
    Abstract: Device and associated methods for detecting a property of a fluid. The device includes a body region and a first flexible element having a first end and a second end. The first end is fixedly located on the body region. The flexible element includes at least a first layer having a first coefficient of thermal expansion and a second layer having a second, different coefficient of thermal expansion. An electrical heater element can be arranged to heat the flexible element to induce bending of said flexible element. The resistance of a first portion of the electrical heater element adjacent the first end can be greater than the resistance of a second portion of the electrical heater element further from the first end. The device can include a heater controller arranged to supply an electrical pulse having a duration less than 5 ms to the electrical heater. The device can include a second, reference flexible element having a first end and a second end, with the first end fixedly located on the body region.
