4.1.2.3 Electronic Ink Sensor

Electronic ink sensors use conductive ink to form the capacitive sensor. Close integration with the front panel is achieved by spraying or printing. The main features are flexible patterns and shorter design cycles, and these sensors are suitable for irregular front panels. Another application scenario is the ITO liquid crystal display, which uses the transparency characteristics of the ITO film. Because the film resistance of electronic printing ink is larger than that of copper, the series resistance must be reduced.
