Abstract | Magnetoelastic resonance is a promising remote sensing technique which has been used for measurement of pressure, fluid flow, temperature, pH density and viscosity [1]. The main component of remote magnetoelastic sensing is a ferromagnetic metal alloy that has the ability to oscillate under the effect of an alternating magnetic field. When frequency of excitation matches with magnetoelastic beam characteristics, these materials resonate. Furthermore, the resulting resonance shifts depending on the pressure, viscosity, and temperature etc. in the vicinity of the beam which can also be collected remotely. This wireless capability without the need for power source makes this technology the most ideal for physiological sensing. Biomedical applications of these sensors are mostly limited to in vitro diagnostic applications [2–5]. The only in vivo application has been within the context of measuring the pH of the stomach in a pig model [6]. While the pig model demonstrated that signals can be transmitted through the belly of a pig, it is unknown as to whether the presence of a thick cortical bone would affect signal transmission. In this study, we assessed the feasibility of magnetoelastic wireless sensing for measuring the viscosity of bone marrow, a viscous fluid that is hidden behind both bone and muscle tissues. |

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.
