Background, Motivation and Objective Ca3NbGa3Si2O14 [CNGS] single crystal has attractive features such as higher electro-mechanical coupling factors, no phase transition up to melting point around 130
Background, Motivation and Objective A key problem in designing an efficient ultrasonic transducer for operating in a low acoustic impedance medium such as air, is the large impedance mismatch between
Background, Motivation and Objective It is desirable to gain a deeper understanding of the mass-loading phenomenon in micro-acoustic devices beyond customary brute-force application of the Finite Elem
Background, Motivation and Objective Langasite (LGS) surface acoustic wave (SAW) pressure sensors can be utilized as battery-free wireless sensors in harsh environments (e.g., rotating cars and truck
Background, Motivation and Objective Because SH-SAW can propagate without the energy leakage into liquid, it is suitable for the liquid sensor to measure conductivity. (11-20) oriented ZnO films whose
Background, Motivation and Objective Implantable temperature sensors find application in surgery and traumatology. The main problem of implantable sensors is the electromagnetic wave propagation loss
Background, Motivation and Objective In order to obtain the high performance of Surface Acoustic Wave (SAW) devices, it is very important for the interdigital transducer (IDT) to be made the unidirect
Background, Motivation and Objective In this paper we present designs of an aluminum nitride (AlN) based mechanical stack for transmit/receive applications in silicon. By optimal design of the mechani
Background,Motivation and Objective Vascular velocity measures by conventional duplex ultrasound can be unreliable since color Doppler is affected by aliasing and beam/flow angle.Several strategies we
Background, Motivation and Objective In ultrasound transducers, the most popular fabrication method for 1-3 piezocomposites (i.e. aligned piezoelectric rods in a polymer matrix) is the ?Dice and Fill?
