Fabrication of a millinewton force sensor, which is based on LTCC technology as an alternative to the widely used alumina (Al2O3) is described. The new sensor, integrated with piezoresistor thick-film, has shown an increase in the sensitivity by two times ...

This paper presents recent work on complete thick-film systems, including dielectrics, conductors and resistors, with a lowered firing temperature range of 450...750°C. These materials allow the extension of proven, reliable and inexpensive thick-film technology to novel applications in electronics and sensors.

Ce travail présente les résultats de mesure sur des capteurs de force à poutre (cantilever), réalisés en technologie des couches épaisses et assemblés par brasure tendre Sn-Ag (Sn96). Les phénomènes de relaxation de la brasure tendre entraînent une dérive du signal de sortie des capteurs. Les résultats sont discutés en fonction de la procédure de brasage et des paramètres géométriques des capteurs (dimensions de la poutre et placement des résistances de mesure), et des recommandations pour la conception de

Object of this work 1) Explore the feasibility of an LTCC microreactor • Chemical stability: compatible with HCl, NaOH, ... • Thermal stability to >100°C 2) Achieve a high degree of integration • Temperature measurement • Reactant flow measurement • Temperature control • Calorimetric chamber

Reliable operation in harsh environments such as high temperatures, high pressures, aggressive media and space, poses special requirements for sensors and packages, which usually cannot be met using polymer-based technologies. Ceramic technologies, especia ...

We formulate a generalized tunneling-percolation model that describes the electrical properties of conductor-insulator cellular disordered systems. This model predicts and explains the experimentally observed universal and nonuniversal behaviors of such pr ...

Project aim: optimised piezoresistive thick-film compositions, especially for low-temperature applications on aluminum alloys, titanium alloys, steel and glass

Fabrication of sensors and micro-fluidic structures from low temperature co- fired ceramic (LTCC) sheets is a growing interest in the micro-packaging community. Such devices usually have inner cavities, whose production is quite complicated. The most elega ...

Dieser Beitrag befasst sich mit einem Viskositätssensor für die Identifikation von Gasen (insbesondere Brenngase). Der Sensor wird aus strukturiertem LTCC (Low Temperature Cofired Ceramic) gefertigt, und besteht aus drei Elementen: 1) Eine beheizte Kavität, 2) eine Membran für Druckmessung, und 3) ein Mäander ("fluidischer Widerstand" / Lecknormal). Im Betrieb wird die Kavität periodisch aufgeheizt und abgekühlt. Dadurch entstehen periodische Über- und Unterdruckpulse, die durch das Lecknormal abfallen und
