| Abstract | Viscosity is one of the characteristic parameters of liquid. The measurement of liquid viscosity is required in many applications. Compared with other acoustic wave device, the shear-horizontal acoustic plate mode wave (SH-APM) device is suitable for liquid sensing. In this paper, the theoretical model of SH-APM device loaded with viscous liquid is built using the propagation characteristics of acoustic wave in laminated mediums, the liquid viscosity is introduced by adding the imaginary part in liquid elastic tensor, and the condition of exciting SH-APM in the piezoelectric plate by inter-digital transducers is researched. Choosing PZT-5H piezoelectric ceramic as substrate material, the numerical calculation is implemented and the SH-APM device is fabricated accordingly. Using different ratios of pure water and glycerol as liquid samples, the validity of liquid viscosity sensing by SH-APM is proved by the experimental results. |

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.
