| Abstract | This paper presents a novel technology which provides a promising solution for designing self-powered microsystems. Micro-Electro Mechanical System (MEMS) energy harvesting is an emerging alternative for scavenging energy from natural sources. It has extensive potential in wireless sensor applications to provide a natural energy source that is essentially inexhaustible. It is an increasingly attractive alternative to costly batteries. This essentially free energy source is available maintenance-free throughout the lifetime of the application. Many systems, such as wireless sensor networks, portable electronics and cell phones, can use this technology as a power source. Although some types of MEMS, such as electro-magnetic MEMS, electrostatic MEMS, and piezoelectric MEMS, are used to provide energy in various applications, they have several technical barriers that limit their applications, including low efficiency, issues of scaling, and high cost. Our novel MEMS solar energy harvesting technology is scalable and also easily integrated in microsystems. The RF MEMS design not only has to provide functional efficiency, but also must work within the limits of maximum charge and discharge conversion efficiency. The energy harvesting technologies currently available which utilizes RF MEMS to convert solar energy into charge, can achieve better benefits than photovoltaic cells. In this paper we provide design, fabrication, testing and evaluation of RF MEMS and its working limits in charging and discharging. |

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.
