Abstract
A capacitive touch-sensitive device includes a transparent substrate unit and at least one patterned transparent electrically-conductive film. The patterned transparent electrically-conductive film is formed on the transparent substrate unit and has a transparent insulating layer and a plurality of mutually and electrically isolated sensor lines that are substantially disposed in the transparent insulating layer. Each of the sensor lines is substantially made of a plurality of non-transparent nano-conductors.

A capacitive touch-sensitive device, comprising:
- a transparent substrate unit;
- and
- at least one patterned transparent electrically-conductive film formed on said transparent substrate unit, wherein:
- said at least one patterned transparent electrically-conductive film comprises:
