TOUCH SENSOR SENSING POSITION AND PRESSURE USING GRAPHENE

摘要

PURPOSE: A simultaneous pressure and position detecting touch sensor is provided to implement a multi-touch function by applying a griffin electrode to a touch sensor. CONSTITUTION: A first griffin electrode pattern is formed in a first material and includes griffins(450). An FSR(Force Sensing Resistor) layer is formed on the first griffin electrode pattern. A second griffin electrode pattern is formed in a second material and includes griffin electrodes. A controller applies an electrode to the first and second griffin electrode patterns and senses resistance variation of the FSR.
