| Abstract | A novel wireless temperature sensor is presented herein for high-temperature applications. This sensor is robust in harsh environments using stable materials and purely passive structures. The resonant frequency of the sensor is determined by the temperature-dependent dielectric constant of the substrate material. The temperature can be wirelessly detected by sensing the resonant frequency of the sensor. The integration of the resonator and antenna enables realization of low-profile and compact sensors. Measured resonant frequency of the sensor decreases from 5.12 to 4.74 GHz when the temperature increases from 50°C to 1000°C. This corresponds to a variation of dielectric constant from 9.7 to 11.2 for the alumina substrate. The presented sensor structure is scalable in size or frequency based on the design requirements. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
