Magneto‐/ electro‐responsive polymers toward manufacturing, characterization, and biomedical/ soft robotic applications

This review article presents various multi-DOF application systems that utilize smart magnetorheological (MR) fluid. It is well known that MR fluid has been actively studied and applied in many practical systems such as vehicle suspension dampers. The design requirements for the effective applications of MR fluid include geometry optimization, working principles, and control schemes. The geometry optimization is mostly related to the size minimization with high damping force, while the working principles are classified into the shear mode, the flow mode, and the squeeze mode depending on the dominant dynamic motion of the application system. The control schemes are crucial to achieve final targets such as robust vibration control against disturbances. It should be addressed that advanced output performances of MR application systems heavily depends on these three requirements. This review article presents numerous application systems such as sandwich structures, dampers, mounts, brakes, and clutches, which have been developed considering the three design requirements. In addition, in this article some merits and demerits of each application system are discussed to enable potential researchers to develop more effective and practical MR application systems featuring the multi-DOF dynamic motions.

Applications of Magnetorheological Fluid Actuator to Multi-DOF Systems: State-of-the-Art from 2015 to 2021

This study on the customer satisfaction towards Nokia mobile phone in Salem City is done keeping in mind the Nokia market trends in the City and also what drives the customer to buy Nokia product. The main objectives of the study are to understand the demographic profile of the sample respondents in Salem City and to evaluate the customer general buying behaviour of NOKIA mobile phones. The analysis has come out with major findings in all aspects of the brand like buying behaviour with respect to Gender, Educational Qualification and Customer Satisfaction Level of the respondents. The analysis has also created a link between the various factors like cost, location, and comparison of Nokia with other company brands available in the market. With respect to the customer perception it has been found out that customers have a positive feedback towards the brand and hence there is ample scope for the sustainability of an exclusive shop in the Salem City.
