ABSTRACT:
A capacitive transducer comprises two plate electrodes positioned in juxtaposed relationship on one surface of a dielectric substrate and an array of segmented electrodes provided on the opposite side of the substrate. Capacitive coupling is achieved between the segmented electrode array and the two plate electrodes. The geometrics of the transducer are such that increasing capacitive coupling is obtained along the main axis of the transducer. An AC signal supplied to one of the plate electrodes of the transducer can be attenuated by physically touching the segmented electrode array. Attenuation can be varied by moving such physical contact along the main axis of the transducer. One or more transducer can be used in a coordinate arrangement to provide an X-Y position indicating device.
