| Abstract | Sidewall friction is of great significance for many MEMS devices such as micromotors, microgears and microhinges. Because sidewalls in MEMS devices are different from in-plane surfaces both chemically and topographically, friction and wear occurring on sidewalls are expected to have its own characteristics. A microtribotester has been developed with the bulk-fabrication technology to measure the sidewall friction and wear, and static friction and dynamic friction measurements have been reported previously. In this paper, experiment results of the microtribotester for a testing period of 55 hours are presented. It is found that the coefficient of dynamic friction reduces gradually with the increase in rubbing cycle, being similar to most macroscale tribopairs. The morphology and chemical components of the wear debris generated in the testing process were analyzed on scanning electron microscope and EDX. From the analysis results, it is concluded that the silicon sidewalls undergoes oxidation during the test. |

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.
