Abstract
An example sensor array includes a first electrode disposed in a first layer, multiple second electrodes disposed in a second layer, and multiple third electrodes disposed outside of the first layer. The second electrodes are galvanically isolated from the first electrode and the third electrodes. In a plan view of the fingerprint sensor array, an area of each third electrode is located within an area of the first electrode.
