Projected capacitive, the touch technology used in the iPhone touch screen, has become the first choice for many small-to-medium, touch-equipped products now in development. Projected capacitive technologies detect touch by measuring the capacitance at each addressable electrode. When a finger or a conductive stylus is near the electrode, it disturbs the electromagnetic field and changes the capacitance of the electrode. This change in capacitance can be measured by the electronics and then converted into X, Y locations that the system can use to detect touch. There are two main types of sensing methods, self-capacitance and mutual capacitance.

An X-Y grid is formed either by etching one layer to form a grid pattern of electrodes, or by etching two separate, parallel layers of conductive material with perpendicular lines or tracks to form the grid; comparable to the pixel grid found in many liquid crystal displays (LCD) Touchscreen Sensors and Industrial Touch Monitors ©
