| Abstract | Piezoelectric microcantilevers (MCs) are a new generation of atomic force microscopy (AFM) beams. They are capable of imaging at a high speed and consuming low energy. These MCs are also built commercially, with non-uniform geometry; and they can be utilised in different environments (gases and liquid). The objective of this Letter is to investigate the vibration behaviour of these types of MCs in liquid. The modelling of the MCs' vibrating motion has been carried out by using the non-uniform beam model, and also by the proposed lumped mass model consisting of three spheres. The obtained results of these two models are compared with each other and with the experimental results. In addition, the effects of liquid mechanical properties, the distance of the MC to the sample surface and also the MC inclined angle at higher fundamental modes are investigated. Sensitivity analysis was performed through the Sobol method to study the effect of the MCs' geometrical dimensions on Reynolds number. Such information can be used to choose appropriate parameters to apply an AFM piezoelectric MC in a liquid environment. |

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.
