Abstract
A method of determining a physical property of a finger using a sensor comprising a two-dimensional measuring arrangement including a plurality of measuring elements, each defining a measuring element position in the measuring arrangement, and each comprising a finger electrode spaced apart from the finger by a dielectric structure. For each measuring element position, the method comprises the steps of performing a first sensing operation using a first capacitive configuration, acquiring a first measurement value for the first capacitive configuration, performing a second sensing operation using a second capacitive configuration, acquiring a second measurement value for the second capacitive configuration. The physical property of the finger is determined based on the first and second measurement values for each measuring element position.
