| Abstract | This paper describes fabrication of a micro force sensor for conduit guided wire which is often used to drive a catheter in medical treatment. The diaphragm type force sensor of 2 mm/spl times/2 mm/spl times/216 /spl mu/m for the conduit with an outer diameter 320 /spl mu/m, an inner diameter 150 /spl mu/m and the wire with a diameter 100 /spl mu/m is fabricated. Photolithography, wet and dry oxidation, B-diffusion, through hole etching by TMAH techniques are used. The relation between loaded force and output voltage is measured to be linear with a sensitivity of 10.2 mV/gf under a constant supplied voltage. A micro master-slave system driven by conduit guided wire is expected to be applied to delicate surgical operations, assembling precise and small parts, etc. This system consists of a micro sized slave robot and a master manipulator of which the size is adapted to a human finger. Displacement and torque of the master side are reduced and transferred to the slave robot by controlling the brake torque against the master torque by feeding back tension signals of the force sensor in the slave robot. The master can feel the tensions by the brake torque, though conduit guided wire has a nonlinear input-output characteristics due to friction force. |

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.
