| Abstract | Integration and assembly of wireless sensor nodes within limited size and volume may not only reduce production cost, but also enable layout-free distribution of autonomous sensor nodes for environmental monitoring, energy consumption management, remote monitoring of civil infrastructure, as well as for biological and human health monitoring. Pursuit of the lowest power consumption of the wireless sensor nodes is another critical issue, which may allow us to use solar cell or other energy harvesting device as the power source, and then reduces the system installation difficulties and maintenance cost. Therefore, in this work, we have engaged in developing a practical applicable approach for flexible assembly of wireless sensor nodes with lowest possible size and lowest power consumption form both system block and physical interconnection points-of-view. A customized RF-transmitter IC (operation frequency: 315MHz) with universal interface to both digital sensors and analog sensors was developed to manage the power consumption of those sensors as well as to reduce the power consumption of data transmission. Buried bump interconnection technology $(B2it^{TM})$ with internal cavities for bare die IC chips and passive components was introduced for 3D integration and assembly of MEMS sensors, customized RF-transmitter IC, crystal oscillator, resistors, capacitors and other passive components. One of the world smallest wireless sensor nodes, 3.9 mm (W)×3.9 mm (D)×3.5 mm (T) (except for power source and antenna), was demonstrated for humidity and temperature monitoring. Power consumption of above sensor nodes was evaluated and compared with our previous prototype, in which a commercial available RF-transmitter IC was integrated for data transmission. The developed approach in this work is believed practically valuable as platform technologies for mass production of wireless sensor nodes as well as for ubiquitous applications of those sensor nodes in wireless sensor networks. |

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.
