Abstract
A sensor cell comprises receiving means, which may be in the form of an electrode coupled to the gate electrode of a thin film transistor T In one form of the invention a voltage supplied to the gate electrode of the transistor T via a switching transistor T is controlled in dependence upon the value of capacitance C arising at the electrode from receipt of a sample for identification. Thus, the operation of transistor T can be used to identify the sample received by the electrode
