Abstract
One embodiment provides a capacitive sensor for determining the presence of an object, such as a user'"'"'s finger or a stylus. The sensor includes a substrate on which electrodes are deposited. A resistive drive electrode is arranged on one side of the substrate and a resistive sense electrode is arranged on the other side of the substrate. A shorting connection connects between two locations on one of the electrodes. The electrodes are connected to respective drive and sense channels.
