The present study manifests the several ground breaking flow phenomena arising out of hydrodynamic interactions between two microorganisms swimming inside a microchannel with close proximity. The results theorized in the present investigation scrutinizes the varying behavior of the ... En savoir plus

Capacitor is mainly defined as two conducting plates that can hold the opposite charges on it. These plates can be used either as a sensor or an actuator. If the relative distance between the two conductors changes as result of given input, then capacitance values will change. This ... En savoir plus

COMSOL Multiphysics software was used to simulate the working of the electrode. The piezoelectric device physics was used to evaluate the displacement created and the potential generated due to piezoelectricity of PDMS. The potential created due to the flow of bio-signals between neurons ... En savoir plus

Zinc Oxide (ZnO) was chosen as the piezoelectric material. A multi – d31 mode cantilever design was used, with varying dimensions of cantilever, to form an array. The individual cantilevers can be either connected in series or in parallel to achieve different output characteristics. ... En savoir plus

Wind speed measurement is a very important factor in various fields such as aeronautics, meteorology and farming. The conventional wind sensor comprises of small mechanical apparatus such as propeller and cup anemometers, or consists of thermal element such as hot wire anemometers, or ... En savoir plus

Wine quality is strongly dependent on the operation parameters of the production process. In batch or fed batch reactors, the rotating velocity should be carefully controlled to avoid cellular stress and ensure adequate mixing of the mixture. Moreover, precise control of substrates ...
