Combined pump-sensor arrangement

A combined pump-sensor arrangement comprising:

• a substrate comprising a first main surface and an opposite second main surface,
• a cap-shaped lid of a package, the lid being arranged on the first main surface of the substrate, wherein the lid forms a hollow that defines a hollow measuring cavity,
• a micropump comprising a pump inlet and a pump outlet, the micropump being configured to suck in an analyte fluid present in the measuring cavity through the pump inlet and eject the same to an environment outside the measuring cavity via the pump outlet,
• a sensor for detecting at least one component of the analyte fluid present within the measuring cavity and movable by means of the micropump,
• wherein both the sensor and the micropump are adjacently arranged on, and in direct contact with, the first main surface of the substrate, and
• wherein the cap-shaped lid contactlessly covers the sensor and the micropump such that both the sensor and the micropump are each arranged inside the hollow measuring cavity formed by the cap-shaped lid.
