Abstract

A contact sensor comprises a first sheet of flexible material and second sheet. The first sheet is capable of being energized to establish an electrical potential thereon. The second sheet can be energized to establish an electrical potential in juxtaposition with the first sheet. The two sheets are formed of materials that tend to stick together. To keep the sheets apart, a plurality of substantially uniform discrete insulating islands are used. By the use of a non-square insulating island spacing pattern with the island spacing satisfying rigorous criteria, the two sheets can be prevented from sticking together without unduly increasing the amount of force required to activate the device. The sensor is particularly useful as a transparent touchscreen.
