Capacitive detection device and methods

Abstract

Summarising the invention, a device is provided. The device comprises a dispensing component configured to draw and dispense liquid, wherein the dispensing component is movable with respect to a liquid sample; and a capacitive sensing component coupled to the dispensing component and configured to detect a plurality of operational states of the dispensing component, wherein each operational state of the plurality of operational states corresponds to a respective capacitance value of a plurality of capacitance values; wherein: the capacitive sensing component has a capacitive sensing range, wherein the capacitive sensing range is a predefined working range for the capacitive sensing component; and the capacitance of at least part of the device is adapted to the capacitive sensing range such that each capacitance value of the plurality of capacitance values is within the capacitive sensing range.
