This disclosure generally provides an input device that includes a multi-layered capacitive sensor which includes a first layer disposed over a second layer that contains a plurality of sensor electrodes coupled to respective traces. The first and second layers form a capacitive sensing stack where the first layer is between the second layer and a touch surface for interacting with the input object. The first and second layers may be disposed on either the same substrate or different substrates in the stack. In one embodiment, the first layer includes electrically floating electrodes and at least one guard electrode. These components may align with respective components in the second layer. For example, the electrically floating electrodes in the first layer may at least partially cover the sensor electrodes in the second layer.
