| Abstract | While radio-frequency based remote powering and back-telemetry is popular for many of the surface implants, like neural prosthesis or under-the-skin implanted batteries, it is not suitable for implants located deep inside the tissue. In this paper, we investigate the feasibility of using a commercial off-the-shelf (COTS), diagnostic ultrasound technology for delivering energy to a $sub-cm^{2}$ sized device implanted at depths more than 10cm away from the tissue surface. Using a COTS 3.5MHz ultrasound scanner we show how the B-mode interrogation protocol can be used to deliver energy to an encapsulated PZT transducer and how the B-mode video sequence can be parsed to retrieve the data from the transducer. In this paper we also discuss the limits of energy transfer at different implantation depths and we also discuss the energy requirements at the implant to achieve robust data transfer. |

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.
