In this paper, we report FEM studies of the effect of unwanted interfering structural vibrations on the performance of an underwater Acoustic Vector Sensor (AVS) performed in the COMSOL Multiphysics simulation tool. An AVS is a compact sensor that measures a four-dimensional vector ... Mehr lesen
FT wind sensors measure wind speed and direction using an acoustic field superimposed on a flow field in an acoustic resonator equipped with three piezoelectric transducers. The study proposed here focuses on the acoustic resonance technology of a simplified wind sensor geometry, and how ... Mehr lesen
Real-time microstructure monitoring is important during the cooling process for hot-rolled strip steel production, as the microstructure formed determines the mechanical properties required by customers. The materials magnetic and electric properties, relative permeability and ... Mehr lesen
Silicon based MEMS have wide applications in under water sensors. This work aims one such applications, hydrophone. Hydrophone detects the pressure variations of acoustic signals and noise in the water and produces an output voltage proportional to the pressure. Here the attempt is made ... Mehr lesen
Mutual Inductance based Level sensor has been proposed for high temperature (1000 C) molten metal applications. Modelling and Simulation studies are done using COMSOL Multiphysics® to obtain optimum sensor design, excitation frequency and sensor characteristics. Further temperature ... Mehr lesen
The detection and identification of the location of a sound source is commonly done using arrays of microphones. A recent new alternative approach has been proposed which involves the use of continuous structures, such as beams or plates, as acoustic wave sensors. The sound wave ... Mehr lesen
The idea of application as a hearing device based on a parasitoid fly, Ormia ochracea has been studied extensively recently. This paper addresses another possible application as an underwater directional sensor. In order to study the feasibility of the application, it is necessary to ... Mehr lesen
Dr Vladislav Djakov is the co-founder of Microvisk Technologies Ltd and the inventor of its MEMS-based Technology. Born in Belgrade, Serbia he came to UK in 1995 to pursue M.Sc. in Artificial Intelligence followed by Ph.D. in Micro-robotics. With over 14 years of extensive ‘hands-on’ ... Mehr lesen
Blind cave fish are capable of sensing flows and movements of nearby objects even in dark and murky water conditions with the help of arrays of pressure-gradient sensors present on their bodies called lateral-lines. To emulate this functionality of lateral-lines for autonomous underwater ... Mehr lesen
A MEMS based electrostatic field sensor is presented which uses capacitive interrogation of an electrostatic force deflected microstructure. The deflection of the sensor is calculated both by simulation and theoretical model and it has been shown that the results of the simulations have ... Mehr lesen
