A capacitive touch sensor includes two sensing layers. Each sensing layer has capacitive sensing strings and electromagnetic antenna strings. Each of the capacitive sensing strings and electromagnetic antenna strings is connected to a highly conductive element. A transparent insulative layer is arranged between the two sensing layers. The two groups of sensing strings on two the capacitive sensing layers orthogonally interlace with each other to form a capacitive sensing matrix.

Composite transparent touch sensor

A capacitive touch sensor includes two sensing layers. Each sensing layer has sensing strings, each of which is composed of sensing units connected in series. An end of each sensing string is provided with a contact. Each sensing string has a wire. Each wire electrically connects to one of the contacts and a string of the sensing units. A transparent insulative layer is arranged between the two sensing layers. The two groups of sensing strings on two the sensing layers interlace with each other to form a sensing matrix.

Structure of transparent capacitive touch sensor

The invention includes a substrate, a touch sensor layer, an insulative film and a signal transmission layer. The touch sensor layer has sensing columns. Each sensing column has a first sensing electrode and second sensing electrodes. The first sensing electrode is connected to a first contact through a first transparent path. Each second sensing electrode is connected to a second contact through a second transparent path. The second contacts are arranged in the same order of the second sensing electrodes connected thereto. The insulative film covers the second contacts. The signal transmission layer has first signal wires, second signal wires and signal output terminals. Two end of each first signal wire are separately connected to the first contact and one of the signal output terminals. Each second signal wire connects the second contacts in a line and is connected to one of the signal output terminals.
