    摘要: The invention relates to the preparation of multilayer microcomponents which comprise one or more films, each consisting of a material M selected from metals, metal alloys, glasses, ceramics and glass-ceramics.The method consists in depositing on a substrate one or more films of an ink P, and one or more films of an ink M, each film being deposited in a predefined pattern selected according to the structure of the microcomponent, each film of ink P and each film of ink M being at least partially consolidated before deposition of the next film; effecting a total consolidation of the films of ink M partially consolidated after their deposition, to convert them to films of material M; totally or partially removing the material of each of the films of ink P. An ink P consists of a thermoset resin containing a mineral filler or a mixture comprising a mineral filler and an organic binder. An ink M consists of a mineral material precursor of the material M and an organic binder. The inks are deposited by pouring or by extrusion.

    摘要: A device for selective detection of gas, enabling a first gas to be detected relative to a second gas, the device having a solid state sensor provided with an insulating substrate having a first face and a second face, a heater element deposited on the first face of said substrate, metal electrodes deposited on the second face of said substrate, and a semiconductor layer formed on said electrode and over the second face of said substrate. Detection is performed by simultaneously determining a voltage U representative of the resistance of the semiconductor element of the solid state sensor and the voltage difference S between a voltage representative of the temperature of the heater element of said solid state sensor and a voltage representative of the temperature of a heater element of a reference sensor, the voltage U and the voltage difference S each being compared with a different and predetermined threshold voltage in order to enable selective detection of gas.

    摘要: The invention provides a reliable, simple, and accurate method for detecting a threshold thickness of a purely-resistive material deposited on a sensor, and providing a response that is independent of the resistivity of the material. The invention provides a measurement method using a sensor comprising at least two electrode pairs having a defined voltage applied thereto generating current between the electrodes, the electrode pairs differing by at least one first parameter selected from the width, the spacing, and the length of the electrodes, and the voltage applied to each pair, and at least one second one of said parameters being adjusted so that a first resistance or a first current between the electrodes of the first pair, and a second resistance or a second current between the electrodes of the second pair are equal when the threshold thickness is reached.
