Abstract:
A sensing device comprising a plurality of sensing elements, each of the sensing elements being configured to provide a signal indicative of an electromagnetic coupling between the sensing element and a finger placed on a surface of the sensing device, a first layer arranged to cover the plurality of sensing elements, the first layer comprising a plurality of recesses, and a second layer arranged to cover the first layer, the second layer having hydrophobic surface properties. There is also provided a method for manufacturing such a sensing device.
