Abstract
A touch sensor includes a first sensing layer, a second sensing layer and an insulative layer therebetween. Each of the first sensing layer and the second sensing layer has capacitive sensing strings and electromagnetic antenna strings. Each capacitive sensing string is composed of capacitive sensing units. The electromagnetic antenna strings are arranged. Each of the capacitive sensing strings and the electromagnetic antenna strings is connected with a tiny wire. The capacitive sensing strings on the first sensing layer are crossed with the second capacitive sensing strings on the second sensing layer to form complementary patterns. The capacitive sensing units on the first sensing layer and the second capacitive sensing units on the second sensing layer form a grid-shaped capacitive sensing unit matrix. The electromagnetic antenna strings on the first sensing layer are crossed with the electromagnetic antenna strings on the second sensing layer to form a grid-shaped electromagnetic antenna matrix.
