| Abstract | A novel flexible tactile sensor for sensing the incident slippage and its direction were designed by introducing the concept of structural electrodes on a piezoelectric film (PVDF). The structural electrodes consisted of an elastomeric column on the top of PVDF film with the distributed microelectrodes underneath the elastomeric column. As an object was placed upon the elastomeric column and pushed by an external force, the occurrence of slippage can be detected by the output voltages from the distributed microelectrodes due to the corresponding bending stresses distributed on the PVDF film. In addition, two opposite output voltages read out from different microelectrodes can differentiate the direction of slippage while the elastomeric column was bent by the friction force between the object and column surface. As the experimental results, two peak voltages happened simultaneously in either compressive-stress area or tensile-stress area when the slippage occurred. Thus, the slippage between the object and elastomeric column can be detected. Besides, the peak value of slippage voltage depends on the height of column and the weight of object. This paper successfully demonstrated the concept of structural electrodes for sensing the incident slippage based on a piezoelectric tactile sensor. |

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.
