Abstract

The present invention relates to a pattern detection method using a touch sensor, and to a capacitive touch sensor which uses the method and which is capable of fingerprint recognition. More specifically, the pattern detection method uses a touch sensor comprising a plurality of finely patterned sensor nodes and is characterised by comprising the steps of: recognising a variation in capacitance depending on the distance between the sensor nodes and a surface which is the object of detection and which has a pattern having concave and convex parts; calculating, on the basis of the variation in capacitance, the vertical distance between each of the sensor nodes and the surface which is the object of detection; and forming the concave-convex pattern of the surface which is the object of detection by combining the above-mentioned vertical distances from the sensor nodes.
