Capacitive touchscreens are coated with a transparent conductive film. When a fingertip comes into contact with a capacitive touchscreen, it can use the conductivity of the human body as a means for input. Electrostatic capacitive touchscreens are used in numerous smartphones such as Apple iPads and iPhones. Unlike IR touchscreens, capacitive touchscreens are highly responsive to a conductive material, yet cannot react to styluses or the touch of a fingernail.
KOGA IR/P-Cap smart pens are widely used on medium and large sized infrared or capacitive
touch screens of various brands. Our smart pen supports 4096 levels of pressure sensitivity, which can help users express original handwriting on the touch screen.
