Abstract: A sensing unit is presented for use in identifying at least one foreign substance in a region of interest. The sensing unit comprises at least one measurement unit, which comprises one or more sensor elements each configured and operable to be responsive to at least one foreign substance in the vicinity thereof. Each sensor element is mounted in its own compartment having an inlet and an outlet thus defining an environmental region in the vicinity of the sensor element separated from the surroundings of the compartment.

Abstract: A piezoelectric crystal element and a sensor utilizing the same are presented for use in a sensor device for identifying at least one foreign material from environment. The crystal element comprises at least one crystal resonator in the form of a inverted mesa structure, which has a membrane-like region and has a certain resonance frequency value. A surface region of the crystal resonator is modified by reactive molecules of a kind capable of interacting with the foreign material to yield a reaction product that effects a change in the resonance frequency of the crystal resonator from said certain resonance frequency value. This change is indicative of the identity and quantity of the foreign material.
