Abstract
A capacitive sensor may include a flex circuit, a substrate facing the flex circuit, and conductive electrodes configured to sense an input applied to the substrate. At least one of the conductive electrodes is associated with a surface of the substrate and an at least one of the electrodes is associated with a surface of the flex circuit.
