Keywords:touch sensing design? layout design guidelines? touch sensing applications?

This application note describes the layout and physical design guidelines used for touch sensing applications. Capacitive sensing interfaces provide many advantages compared to mechanical user interfaces. They have a modern look and feel, and are easy to clean, waterproof and robust.

Capacitive sensing interfaces are used more and more in a wide range of applications. The main difficulty designing such interfaces is to ensure that none of the items interfere with each other.

This application note provides simple guidelines concerning three main aspects: the PCB; overlay and panel materials; and all other items in the capacitive sensor environment.
