Abstract
Touch sensors with multiple electrically isolated touch regions are disclosed. A touch sensor may include a first substrate and a second substrate. The first substrate may include two or more resistive layers covering two or more separate areas. The second substrate may include a continuous resistive layer that partially overlaps with each of the two resistive layers of the first substrate. The touch sensor may also include a first controller electrically connected to the continuous resistive layer of the second substrate and electrically connected to a first one of the two resistive layers of the first substrate, forming a first independently operable region. The touch sensor may further include a second controller electrically connected to the continuous resistive layer of the second substrate and electrically connected to a second one of the two resistive layers of the first substrate, forming a second independently operable region.
