The paper presents a method of extraction of coupling of modes (COM) parameters for a one port surface acoustic wave (SAW) resonator from the results of finite element analysis in COMSOL Multiphysics®. The COM parameters calculated are electromechanical coupling coefficient, reflection ... Read More
In our work, simulations of a piezoelectrical micromachined ultrasonic transducer compatible with CMOS-MEMS process are presented. The piezoelectric material of the PMUT is AlN sandwiched between two Al layers and a top Si3N4 passive layer. The piezoelectric and the metal materials have ... Read More
Finite Element simulations are becoming an increasingly powerful tool in the transducer design process. The development of user-friendly software and predefined interfaces able to provide physics setup to predict the loudspeaker complex behavior helps designers in the product development ... Read More
Surface acoustic wave gas sensors use a chemically sensitive resistive layer to detect gas concentration. The resistivity of the sensing material, the sensing layer thickness, and the spacer layer thickness all affect the surface wave propagation velocity. Existing analytic theory ... Read More
This paper discusses the simulation studies on a vibration based energy harvesting system to convert the undesirable mechanical vibration to useful green power. The design consists of a resonating proof mass and a spring system enclosed in housing and fixed on the source of vibration. A ... Read More
This paper presents a methodology towards designing, analyzing and optimizing piezoelectric interdigitated microactuators using COMSOL Multiphysics. The models used in this study were based on a circularly interdigitated design that takes advantage of primarily the d{;sub}33 ... Read More
Introduction Leaky Surface Acoustic Wave (LSAW) resonators in rotated Y-X cut Lithium Tantalate (LiTaO3) are widely used for resonator based ladder filters in telecommunication applications. These devices make use of quasi- shear waves confined to the surface of the piezoelectric layer ... Read More
For active Structural Health Monitoring (SHM), one popular sensor type is the piezoelectric wafer active sensor (PWAS) due to its multi-purpose application as actuator and sensor and its low cost. It is used to generate a wave field, which interacts with the structure and is recorded by ... Read More
Photoacoustic (PA) imaging has matured into a clinical modality for tissue imaging and functional cancer cell research. It uses a pulsed laser to irradiate a region and generate a thermally-induced acoustic pressure wave that can be collected by an ultrasound transducer. The optical ... Read More
