Principles of Capacitance Capacitive touch technology works on the principle of capacitance, which is the ability of a material to store an electric charge. Capacitance is created when two conductive materials are placed close together but not touching. When a voltage is applied to one of the conductive materials, an electric field is created between the two materials. The closer the two materials are, the stronger the electric field and the higher the capacitance. Touch Sensing Methods There are two primary methods for sensing touch with capacitive touch technology: self-capacitance and mutual capacitance. Self-capacitance measures the change in capacitance of a single conductive material, such as a finger, as it comes into contact with a conductive surface. Mutual capacitance measures the change in capacitance between two conductive materials, such as a finger and a conductive surface, as they come into contact with each other.
