On nearfield acoustic holography
Such functions u are called radiating solutions. Pressure measurements are taken by acoustical sensors located in a domain Ω0 inside or outside the cabin or on a surface Γ0 = ∂Ω0 . Our goal is to reconstruct u inside Ω, or the normal velocity v = ∂νu on Γ = ∂Ω, (ν is the unit exterior normal to ∂Ω). This is a mathematical model of the nearfield acoustic holography [W], [Wu]. H(m)(Ω) denotes the...
متن کاملDesign and Fabrication of Piezoelectric Acoustic Sensor
This paper describes a fully integrated acoustic sensor that combines high sensitivity, wide frequency range and low cost of batch processed miniaturized silicon components. A sputtered piezoelectric ZnO layer transforms the mechanical deflection of a thin-etched-Si diaphragm into a piezoelectric charge. ZnO has transparent and conductive properties, which makes it attractive for a variety of s...
متن کاملPolyaniline Nanofiber Based Surface Acoustic Wave Gas Sensors—Effect of Nanofiber Diameter on H2 Response
A template-free rapidly mixed reaction was employed to synthesize polyaniline nanofibers using chemical oxidative polymerization of aniline. Hydrochloric acid (HCl) and camphor sulfonic acid (CSA) were used in the synthesis to obtain 30and 50-nm average diameter polyaniline nanofibers. The nanofibers were deposited onto layered ZnO/64◦ YX LiNbO3 surface-acoustic-wave transducers. The sensors we...
متن کاملBiomimetic Acoustic Sensor Using Single Crystal Piezoelectric Cantilever Array
A biomimetic acoustic sensor was fabricated with single crystal PMN-PT piezoelectric cantilever array that can mimic functional properties of mammalian cochlea. Basilar membrane of mammalian cochlea can separate frequency components of input sound source and Ion channel phenomenon of hair cells on basilar membrane can generate action potentials for stimulating a nerve site. The piezoelectric ca...
متن کاملAcoustic Sensor Arrays with Small Baseline
Aeroacoustic sensing is well motivated due to its passive nature and low bandwidth, and processing with array baselines of one to a few meters is well studied and useful. However, arrays of this size present difficulties in manufacture and deployment. Motivated by the desire to develop smaller, cheaper (perhaps “disposable”) sensor packages, we consider performance for arrays with small baselin...
