Abstract:
The present invention relates to an electronic device comprising a fingerprint sensing system including a plurality of sensing elements, each being configured to capacitively couple to a finger arranged adjacent to the sensing element and to provide a sensing signal indicative of a response to a time-varying finger excitation signal provided to the finger; and an electrically conducting housing at least partly enclosing an interior of the electronic device. The electronic device further comprises housing connection circuitry connected to the electrically conducting housing, and arranged and configured to at least intermittently allow a potential of the electrically conducting housing to follow the finger excitation signal. Hereby the housing can be used to enhance the functionality of the fingerprint sensing system.
