| Abstract | Monolithic fabrication and advancements in MEMS and nanotechnology have made biomedical implants more popular for monitoring and other applications in humans and animals. One of the primary challenges faced in employing implants is providing a stable battery-less power supply. Inductive coupling is a commonly used means of transferring energy to implanted devices requiring power in milliwatt or microwatt range. Similar to passive RFID tags, an external transmit-coil may be used to induce a current in an implanted receive-coil by generating a magnetic field in the vicinity. However, it must be realized that the physical design of inductive coils and their orientation with respect to each other has a direct impact on the inductive link circuit, and power delivery. This paper focuses on developing three dimensional mathematical models of the magnetic field of spiral and solenoid coils to investigate the effect of lateral misalignment on the mutual inductance of the coils. Finite Element Method (FEM) simulations of the spiral and solenoid transmit coils are carried out to validate the developed models. Coil circuit parameters such as inductance, resistance and quality factor are also given. |

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.
