Resistive Touch Panel

Resistive touch panels are composed of two flexible sheets coated with a resistive material and separated by an air gap or microdots. When contact is made to the surface of the touchpanel, the two sheets are pressed together. On these two sheets there are horizontal and vertical lines that when pushed together, register the precise location of the touch. Because the touchpanel senses input from contact with nearly any object (finger, stylus/pen, palm) resistive touch panels are a type of "passive" technology.
