| Abstract | Direct-write of piezoresistive photopolymers is regarded as a promising means to produce compliant tactile sensors. In this work, a multi-layer compliant tactile sensor was developed using a hybrid manufacturing process including soft molding, micro-dispensing and photopolymerization processes. The working principle of the suggested sensor is to detect changes in resistance as it is deformed. A compliant skin structure was built layer-by-layer using a soft polyurethane material to cover the piezoresistive sensing elements. These sensing elements were created from stretchable photocurable conductive carbon nanotube (CNT)/prepolymer nanocomposites, which were deposited by the micro-dispensing process within the polyurethane skin layers and cured during the molding process. The fabricated tactile sensor consists of two layers of sensing elements within the skin structure; there are eight stretchable straight wires in each layer. The wires in the second layer were orthogonally placed on top of the first layer so that the sensor can detect various external forces/motions in two dimensions. The fabricated sensor was characterized by several experiments such as position, and 2D pattern detection. Finally, it is concluded that the tactile sensor using the hybrid manufacturing method and materials is promising for various applications such as robotics, prosthetics, and wearable electronics. |

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.
