项目摘要

Temperature measurements are an essential part of the automatic control of industrial processes. Especially for the control and optimization of high temperature processes (e.g. combustion), measurement setups up to 1000 °C and beyond are required, and, therefore, a remote or wireless measurement is often beneficial or mandatory. Several possibilities exist to measure extremely high temperatures wirelessly, e.g. infrared thermometers or SAW temperature sensors. However, most of the approaches don't use a dedicated sensor element that resides in the hot environment, which would allow for more accuracy and non-line of sight operation, and approaches that do use a dedicated sensor element are limited either in operation duration or by a low maximum operation temperature. Chipless wireless sensor technology is a promising approach to solve these issues and provide sensors that even allow wireless readout through thick dielectric temperature shielding of furnaces. Especially the use of dielectric resonators (DR) has proven extremely reliable and versatile. However, the relationship of parameters for appropriate system layout are rather unknown to date, since research on this topic, inside and outside of the research team that proposes this project, is limited by available materials, and sensor and system optimization was hardly performed for the electromagnetic as well as for the material science part. Therefore, the task of the proposed project is the research on inorganic composites and new electromagnetic resonator structures to enable a high number of degrees of freedom for sensor system design.The central idea of the project is the design of DRs from layered dielectrics. A composition of high-Q (low loss), low permittivity materials without noticeable temperature dependence, and low-Q, high permittivity materials that are highly temperature dependent will lead to a broad range of different optimization directions, e.g. for broad temperature range sensors with moderate resolution or for highly accurate sensors in a narrow temperature window. First, the novel layered DR concept will be investigated at low temperatures with known materials. In a second step, the concept will be transferred to higher temperatures by the utilization of newly investigated materials. Eventually, both, temperature-independent and engineerable temperature-dependent materials are required to realize the RFID and the sensor part of a fully integrated RFID sensor tag.While the main application of such sensors serves as the general motivation, the layered DR approach can be utilized for the characterization of low-Q materials at extremely high temperatures, thus delivering a new characterization concept as well as first characterization data for the materials that are investigated for the sensor. Therefore, the investigation of a novel, model-based characterization method for dielectric parameters based on layered DRs is the another task of the project.
温度测量是工业过程自动控制的重要组成部分。特别是对于高温过程(例如燃烧)的控制和优化,需要高达1000 °C及以上的测量设置,因此远程或无线测量通常是有益的或强制性的。无线测量极高温度有几种可能性,例如红外温度计或SAW温度传感器。然而,大多数方法不使用驻留在热环境中的专用传感器元件,这将允许更高的准确性和非视线操作,并且使用专用传感器元件的方法在操作持续时间或低的最大操作温度方面受到限制。无芯片无线传感器技术是解决这些问题的一种有前途的方法,并提供甚至允许通过炉的厚电介质温度屏蔽进行无线读出的传感器。特别是介质谐振器(DR)的使用已被证明是非常可靠和通用的。然而,迄今为止,用于适当系统布局的参数的关系是相当未知的,因为在提出该项目的研究团队内部和外部对该主题的研究受到可用材料的限制,并且几乎没有对电磁和材料科学部分进行传感器和系统优化。因此,本项目的任务是研究无机复合材料和新的电磁谐振器结构,以实现传感器系统设计的高自由度。本项目的中心思想是设计层状介质的DR。没有明显温度依赖性的高Q(低损耗)、低介电常数材料和高度温度依赖性的低Q、高介电常数材料的组合物将导致宽范围的不同优化方向,例如用于具有中等分辨率的宽温度范围传感器或用于窄温度窗口中的高精度传感器。首先,将在低温下使用已知材料研究新型分层DR概念。在第二步中,将通过利用新研究的材料将概念转移到更高的温度。最终,需要温度无关和可工程化的温度相关材料来实现RFID和完全集成的RFID传感器标签的传感器部分。虽然这种传感器的主要应用是一般动机,但分层DR方法可用于在极高温度下表征低Q材料,从而为传感器研究的材料提供新的表征概念以及第一表征数据。因此,研究一种新的,基于模型的表征方法的介电参数的分层DR的基础上,是该项目的另一个任务。
