Although ceramics have been known to mankind literally for millennia, research has never ceased. Apart from the classic uses as a bulk material in pottery, construction, and decoration, the latter half of the twentieth century saw an explosive growth of application fields, such as electrical and thermal insulators, wear-resistant bearings, surface coatings, lightweight armour, or aerospace materials. In addition to plain, hard solids, modern ceramics come in many new guises such as fabrics, ultrathin films, microstructures and hybrid composites. Built on the solid foundations laid down by the 20-volume series Materials Science and Technology, Ceramics Science and Technology picks out this exciting material class and illuminates it from all sides. Materials scientists, engineers, chemists, biochemists, physicists and medical researchers alike will find this work a treasure trove for a wide range of ceramics knowledge from theory and fundamentals to practical approaches and problem solutions.

Whilst printed films are currently used in varied devices across a wide range of fields, research into their development and properties is increasingly uncovering even greater potential. Printed films provides comprehensive coverage of the most significant recent developments in printed films and their applications. Materials and properties of printed films are the focus of part one, beginning with a review of the concepts, technologies and materials involved in their production and use. Printed films as electrical components and silicon metallization for solar cells are discussed, as are conduction mechanisms in printed film resistors, and thick films in packaging and microelectronics. Part two goes on to review the varied applications of printed films in devices. Printed resistive sensors are considered, as is the role of printed films in capacitive, piezoelectric and pyroelectric sensors, mechanical micro-systems and gas sensors. The applications of printed films in biosensors, actuators, heater elements, varistors and polymer solar cells are then explored, followed by a review of screen printing for the fabrication of solid oxide fuel cells and laser printed micro- and meso-scale power generating devices. With its distinguished editors and international team of expert contributors, Printed films is a key text for anyone working in such fields as microelectronics, fuel cell and sensor technology in both industry and academia. Provides a comprehensive analysis of the most significant recent developments in printed films and their applications Reviews the concepts, properties, technologies and materials involved in the production and use of printed films Analyses the varied applications of printed films in devices, including printed restrictive sensors for physical quantities and printed thick film mechanical micro-systems (MEMS), among others

Die Sensorik nimmt im Automobil einen bedeutenden und stark wachsenden Stellenwert ein. Im Zuge der rasanten Entwicklungen auf dem Gebiet der Fahrzeug-technik, wie Automatisiertes Fahren und E-Mobilität, sind immer genauere und robustere Sensorinformationen unabdingbar. Diese Informationen werden in komplexen Regelalgorithmen der Fahrzeugelektronik insbesondere zur Objekterkennung, Systemüberwachung, Motorsteuerung, Fahrstabilität, Sicherheits- und Komforterhöhung genutzt. Zur Generierung dieser Informationen gewinnen neben der Optimierung bekannter Sensorprinzipien zunehmend auch neue Sensorkonzepte und -technologien an Bedeutung. Die resultierenden Sensorsysteme unterliegen neben den hohen technischen Anforderungen auch immer höheren Ansprüchen hinsichtlich Kosten, Miniaturisierung, Qualität und Zuverlässigkeit. In diesem Fachbuch sind Sensorprinzipien und -techno¬logien beschrieben, die den Trend aktueller Sensorentwicklungen für spezielle Fahrzeug-Anwendungsgebiete widerspiegeln. Der Schwerpunkt dieser Ausgabe liegt auf Sensorsystemen, die ihren Einsatz im Bereich Automatisiertes Fahren, Batterie-Zellüberwachung in Elektrofahrzeugen, Motorsteuerungen, Abgasregelungen, Klimatisierung und aktive Sicherheit im Automobil finden.

Advances in aerospace technologies demand new ways to package electronics for high temperature and harsh environments. One packaging method of interest in academia and industry is Low Temperature Co-fired Ceramic (LTCC). LTCC is a multi-layer design and packaging system that can embed passive components and thermal management structures within a substrate. This thesis compiles research done to evaluate LTCC as a high-performance electronic packaging technique by determining the performance of embedded passives and thermal management structures at temperatures from -55°C to 225°C. The passive structures and thermal management structures are evaluated using theoretical calculations, simulations, and measurements of fabricated devices.

Microwave dielectric materials play a key role in our global society with a wide range of applications, from terrestrial and satellite communication including software radio, GPS, and DBS TV to environmental monitoring via satellite. A small ceramic component made from a dielectric material is fundamental to the operation of filters and oscillators in several microwave systems. In microwave communications, dielectric resonator filters are used to discriminate between wanted and unwanted signal frequencies in the transmitted and received signal. When the wanted frequency is extracted and detected, it is necessary to maintain a strong signal. For clarity it is also critical that the wanted signal frequencies are not affected by seasonal temperature changes. In order to meet the specifications of current and future systems, improved or new microwave components based on dedicated dielectric materials and new designs are required. The recent progress in microwave telecommunication, satellite broadcasting and intelligent transport systems (ITS) has resulted in an increased demand for Dielectric Resonators (DRs). With the recent revolution in mobile phone and satellite communication systems using microwaves as the propagation media, the research and development in the field of device miniaturization has been a major challenge in contemporary Materials Science. In a mobile phone communication, the message is sent from a phone to the nearest base station, and then on via a series of base stations to the other phone. At the heart of each base station is the combiner/filter unit which has the job of receiving the messages, keeping them separate, amplifying the signals and sending then onto the next base station. For such a microwave circuit to work, part of it needs to resonate at the specific working frequency. The frequency determining component (resonator) used in such a high frequency device must satisfy certain criteria. The three important characteristics required for a dielectric resonator are (a) a high dielectric constant which facilitates miniaturization (b) a high quality factor (Qxf) which improves the signal-to-noise ratio, (c) a low temperature coefficient of the resonant frequency which determines the stability of the transmitted frequency. During the past 25 years scientists the world over have developed a large number of new materials (about 3000) or improved the properties of known materials. About 5000 papers have been published and more than 1000 patents filed in the area of dielectric resonators and related technologies. This book brings the data and science of these several useful materials together, which will be of immense benefit to researchers and engineers the world over. The topics covered in the book includes factors affecting the dielectric properties, measurement of dielectric properties, important low loss dielectric material systems such as perovskites, tungsten bronze type materials, materials in BaO-TiO2 system, (Zr,Sn)TiO4, alumina, rutile, AnBn-1O3n type materials, LTCC, ceramic-polymer composites etc. The book also has a data table listing all reported low loss dielectric materials with properties and references arranged in the order of increasing dielectric constant. Collects together in one source data on all new materials used in wireless communication Includes tabulated properties of all reported low loss dielectric materials In-depth treatment of dielectric resonator materials
