Microelectromechanical coupled resonating arrays are being used for detecting biological and chemical analytes through mass sensing. Such arrays of perfectly identical resonators can be considered as periodic, ordered, non-localized systems. The change in the eigen parameters of the ... Mehr lesen
The paper presents finite element simulation of a surface acoustic wave (SAW) linear motor. The function of SAW linear motor depends on the principle of friction drive provided by SAW propagating on a piezoelectric substrate. The SAW motor comprises of a slider driven by Rayleigh wave ...

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
In this paper, a free membrane is used as a receiver to increase the capacitance and therefore the resolution of the flow meter. For the current application, from the wavelength of sound wave in soft tissue (c= 1540 m/s) the resolution was calculated to be 0.48 mm. This gives the first ... Mehr lesen
This paper concentrates on developing a self-contained cochlea whose performance is at par with natural hearing. The Artificial Basilar Membrane (ABM) design is done in such a manner so as to get a performance similar to the natural hearing. Finite element analysis was done with the help ... Mehr lesen
Perforated pipes are extensively used to control exhaust noise in automobiles [1-4]. The energy loss associated with the perforations leads to back pressure which needs to be quantified and minimized [5]. An objective approach presented in [6] is the introduction of friction factor for ... Mehr lesen
This study aims to develop and validate a finite element numerical model to represent the Insertion Loss (IL) promoted by the enclosure of a sound source. For the validation, a enclosure prototype was built in wood and the IL was measured in laboratory. The idea is to develop an ... Mehr lesen
In this contribution, we simulate the optical response of piezoelectric planar optical microcavities (POMCs) under the modulation introduced by a propagating surface acoustic wave (SAW). The physical picture of the model is shown in Figure 1. A metallic interdigital transducer (IDT) is ... Mehr lesen
