The conductive surfaces are held apart by "spacer dots", usually glass beads that are silk-screened onto the coated glass.
    When a person presses on the top sheet, its conductive side comes in contact with the conductive side of the glass, effectively closing a circuit (this is called pressure sensing). The voltage at the point of contact is read from a wire connected to the top sheet.It can be touched by finger, gloved finger, leather or stylus pen.It is inherently of many advantages such as high accuracy, quick response, drift-free, stable and long durability for a life time of 1,000,000 times finger touches.
