A touch sensor pattern with a secondary sensor formed substantially as part of the touch sensor pattern is provided. By forming the secondary sensor substantially as part of the touch sensor pattern, where the secondary sensor can be held at a steady state or ground during a touch scan cycle of the touch sensor, an overall thickness of the stackup at the area of the touch sensor where the secondary sensor is formed can be significantly reduced. The reduction in the thickness can allow more space for other hardware such as a device battery, for example. Moreover, grounding the secondary sensor can shield the touch sensor pattern at the area of the touch sensor pattern where the secondary sensor is formed, during a touch scan cycle.
