Inventors include Pillzota, Teuta; Janardanan, Amritha; Flewellen, James; Sonmezoglu, Soner; and Maharbiz, Michel.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: A sensing device for sensing a rotational property and/or a further property associated with one or more objects, for example, nanometre or micron sized objects in a fluid, the device comprising: two or more driving elements and associated driving circuitry configured to drive said driving elements using two or more respective signals characterised by a difference in at least their phase and/or other electrical property; at least one sensing element configured to sense a response signal in response to driving the driving elements using the two or more signals, wherein a difference in at least the phase and/or other electrical property of the two or more respective signals causes the sensed response signal to be dependent on at least a difference in impedance between each of the two or more driving elements and the at least one sensing element such that a rotational property and/or at least one further property associated with the one or more objects is obtainable from the sensed response signal, wherein the rotational property and/or at least one further property comprises a speed of rotation and/or a frequency of rotation and/or a direction of rotation and/or a change in direction of rotation.
