    摘要: A cartridge-like chemical sensor is formed by a housing having a base and a cover fixed to the base and provided with an input opening, an output hole and a channel for a gas to be analyzed. The channel extends in the cover between the input opening and the output hole and faces a printed circuit board carrying an integrated circuit having a sensitive region open toward the channel and of a material capable to bind with target chemicals in the gas to be analyzed. A fan is arranged in the housing, downstream of the integrated device, for sucking the gas after being analyzed, and is part of a thermal control system for the integrated circuit.

    摘要: An electronic microbalance made in a semiconductor body accommodating an oscillating circuit adjacent to a diaphragm. A stack formed by a first electrode, a second electrode, and a piezoelectric region arranged between the first and the second electrode extends above the diaphragm. Any substance that deposits on the stack causes a change in the mass of the microbalance and thus in the resonance frequency of a resonator formed by the microbalance and by the oscillating circuit and can thus be detected electronically. A chemical sensor is obtained by forming a sensitive layer of a material suitable for binding to target chemicals on the stack. The sensitivity of the microbalance can be increased by making the first electrode of molybdenum so as to increase the piezoelectric characteristics of the piezoelectric region.

    摘要: The microreactor is formed by a sandwich including a first body, an intermediate sealing layer and a second body. A buried channel extends in the first body and communicates with the surface of the first body through a first and a second apertures. A first and a second reservoirs are formed in the second body and are at least partially aligned with the first and second apertures. The sealing layer separates the first aperture from the first reservoir and the second aperture from the second reservoir, thereby avoiding contamination of liquids contained in the buried channel from the outside and from any adjacent buried channels. The sealing layer is perforated during use of the device, but a resilient plug can be used to reseal the device.
