  • Sensor cell
    Patent number: 6657269
    Abstract: A sensor cell comprises receiving means, which may be in the form of an electrode 10 coupled to the gate electrode of a thin film transistor T1. In one form of the invention a voltage supplied to the gate electrode of the transistor T1 via a switching transistor T7 is controlled in dependence upon the value of capacitance CA arising at the electrode from receipt of a sample for identification. Thus, the operation of transistor T1 can be used to identify the sample received by the electrode 10.
    Type: Grant
    Filed: December 20, 2001
    Date of Patent: December 2, 2003
    Assignee: Seiko Epson Corporation
    Inventors: Piero Migliorato, Nathan Bavidge, Christopher Lowe
