气象微系统中微控制器要完成多个传感器的软件温度补偿,同时也要完成通讯、监测、控制等一系列功能,因而微控制器的数据处理量很大,系统中程序、数据需要的存储空间也很大。我们针对这一问题对软件温度补偿的算法进行了改进,减少了微控制器的数据处理量,并减少了系统中程序、数据所占的存储空间。考虑判系统中有多个传感器需要进行温度补偿,因而算法的改进对于气象微系统向灵巧型、便携式、高性能方向发展具有实用意义。  相似文献

The considerable investment in silicon technology has rarely addressed device use in harsh environments such as high temperatures, aggressive media, and radiation exposure. A clear future requirement is to save weight, volume, and reduce costs in “unfriendly” environments like high temperatures. This can be achieved either by cooling systems or by electronic microsystem components suited to withstand high temperatures. The current status of cooling systems, harsh-environment sensors, and microsystems in view of markets, realized devices, material, properties, process maturity, and packaging technologies are reviewed. Possible semiconductor candidates for high-temperature applications are discussed. The main obstacles for the future of high-temperature and harsh-environment microsystems is highlighted  相似文献

The authors predict that scaled-down, ultra-low-power ICs and shrinking form-factors will hasten the arrival of on-demand services. Thus in total, advances in the various device and system technologies for conserving energy will deliver enormous system benefits. At the end of this decade and early into the next century, most portable microsystems will operate at around 1 V. The energy will be supplied by a single battery cell or solar cells. Progress in microelectronics and I/O devices will encourage shrinking form factors. At the lower form factors, personal systems will become unobtrusive and truly personal. Highly energy-efficient, ultra-low power 1-V microsystems will make possible the low-cost, battery-operated, portable systems needed to propel personal communication, entertainment, and information services. For these services to gain market acceptance, however, their benefits must be commensurate with cost. In their discussion the authors place emphasis on the developments in integrated circuit technologies  相似文献

Microsystem technologies are the basis for the realization of miniaturized, intelligent embedded systems. Microsystems are characterized by the optimized application of “microtechnologies” and “systems engineering concepts”. Microtechnologies, e. g microelectronics, micromechanics and microoptics are those fabrication technologies which enable miniaturization. Packaging and interconnect technologies enable the configuration of individual components, innovative concepts for system architectures and signal processing enable the integration and optimization of components into systems and finally the concepts of systems engineering allow for the complex design process by attaching methodologies and computer aided tools for planning, specification, modeling, simulation, design, verification and test. Designing, verifying and testing microsystems and microsystem components will not be feasible without the intensive use of design methodologies and supporting computer aided design tools (CAE, CAD, CASE, CAT, ...)  相似文献

The by far leading technology for manufacturing MEMS devices is Si-micromachining with its various derivatives. However, many applications of microsystems have requirements on materials basis, geometry, aspect ratio, dimensions, shape, accuracy of microstructures, and number of parts that cannot be fulfilled easily by mainstream silicon-based micromachining technologies. LIGA, an alternative microfabrication process combining deep X-ray lithography, plating-through-mask and molding, enables the highly precise manufacture of high-aspect-ratio microstructures with large structural height ranging from hundreds to thousands of micrometers thick. These tall microstructures can be produced in a variety of materials with well-defined geometry and dimensions, very straight and smooth sidewalls, and tight tolerances. LIGA technology is also well suited for mass fabrication of parts, particularly in polymer.Many microsystems benefit from unique characteristics and advantages of the LIGA process in terms of product performance. The LIGA technology is briefly reviewed. The strengths of the manufacturing method and its main fields of application are emphasized with examples taken from various groups worldwide, especially in micromechanics and microoptics.  相似文献

Additionally to the very large scale integrated information processing systems, the second Silicon revolution brings non-electrical functions on the same chip. Chips emerge which are able to sense, to think, to act and to communicate. They are beginning to penetrate into all spheres of human life. Low production costs and mature manufacturing technologies are necessary preconditions for the commercial success. Therefore, going back to the well-proven and costefficient microelectronic technologies and production plants was one of the most important ways towards the broad market penetration of microsystems. However, an extension of the microelectronic technologies is inevitable. In the paper, based on the microsystem development activities of Austria Mikro Systeme Int., problems of microsystem development and solutions are presented for a microelectronic compatible manufacturing environment. With it, the paper describes CMOS compatible products like magnetosensor-IC’s based on Hall elements, mechanical systems like acceleration sensors and specific pre-and post-processing process extensions with service possibilities for external organisations.  相似文献
