<p>A capacitive sensor includes a plurality of sensing electrodes patterned on at least one substrate and spread over sensing area of the sensor and at least one conductive area other than the plurality of sensing electrodes pattern on at least one substrate and spread on the sensing area of the sensor, wherein the at least one conductive area is capacitively coupled to at least one of the plurality of sensing electrodes and is electrically isolated from each of the plurality of sensing electrodes, and wherein only the plurality of sensing electrodes is adapted to be electrically connected to circuitry during operation of the sensor. A digitizer system comprises the capacitive sensor and circuitry electrically connected to the plurality of sensing electrodes, the circuitry adapted for detecting output from the plurality of sensing electrodes, wherein the at least one conductive area is electrically isolated from the circuitry.</p> |
