| Abstract | The wireless capsule endoscopic MEMS for diagnosing human gastrointestinal tract is a great break-through. The system overcomes some disadvantages of the traditional push endoscope and causes less comfortlessness for patients. Some kinds of capsule endoscopes have been successfully put into practical use as a diagnostic tool for the digestive system, especially in small intestine. It is found that some problems, such as the supplying power by the battery is limited and the security is not reliable enough. In the present paper, a detailed analysis of the techniques for outside power supply of the endoscope is presented. One wireless power transmission method is based on electromagnetic coupling principles, combining with electric power and electron technology. Firstly, the concepts and the basic principles of a loosely inductively coupled power system are introduced. Different from a traditional transformer, an equivalent electronic circuit is set up with the mutual inductive model on electromagnetic coupling, and then a wireless inductive power transmission mathematical model can be established. With numerical calculation and simulation of the system, the influences of electromagnetic coupling geometrical and electrical parameters on the performance of the wireless power transmission system are discussed. With analysis of possibility for the wireless power transmission of the capsule endoscope, the transmission sketch is proposed. |

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.
