Abstract
The invention relates to a sensing device for a portable apparatus, in particular a portable telecommunication device or a wearable device, the sensing device comprising an acoustic wave sensing mechanism, like a microphone; and a gas sensing mechanism, wherein the acoustic wave sensing mechanism and the gas sensing mechanism are integrally formed. The invention furthermore relates to an electronic device comprising such a sensing device. In addition, a method is provided that allows calibrating a gas volume based on an output signal of an acoustic wave sensing mechanism.
