“…The base velocity u b is a function of system buoyancy and the pressure amplitude, and equals the acoustic particle velocity when the vector sensor is neutrally buoyant (B = 1). The accelerometer exhibits a dipole directivity pattern, because the base velocity is proportional to the cosine of the pressure angle of incidence h. The pressure sensitivity of the cantilever beam accelerometer on its acoustic axis is obtained from equations (14) and (15):…”

“…Relaxor-ferroelectric single crystals, such as lead magnesium niobate-lead titanate (PMN-PT) and lead zinc niobate-lead titanate (PZN-PT) can provide significant advantages for underwater acoustic transducers because their piezoelectric properties are superior to those of polycrystalline ceramics such as lead zirconate titanate (PZT) [14,15]. Acoustic projectors with single crystals can have high source levels in broadband frequency because single crystals have high electromechanical coupling coefficients (k~0.9) and large piezoelectric constants (d !…”

Directional sound detection using vector sensors rather than large hydrophone arrays is highly advantageous for target detection in SONAR. However, developing highly sensitive and compact vector sensors for use in a system whose size is limited has been a challenging issue. In this paper, we describe a miniaturized acoustic vector sensor with piezoelectric single crystal accelerometers for the application in towed line arrays. A mass-loaded cantilever beam accelerometer with a [011] poled PIN-PMN-PT single crystal shows a better signal-to-noise ratio compared to accelerometers with other piezoelectric materials because of its superior piezoelectric properties in the 32 direction. We suggested a sufficiently compact vector sensor by using a cylindrical hydrophone with 10 mm in diameter as a housing of the single crystal accelerometers. Two single crystal accelerometers were orthogonally mounted inside the cylindrical hydrophone to detect direction of sound in the transverse plane of the line array. The receiving voltage sensitivity of the accelerometers and hydrophone was −199 and −196 dB, respectively, at 3 kHz. The directional cardioid beams generated by summing the omnidirectional beam from the hydrophone and the dipole beam from the accelerometers were validated over the entire operating frequency.

“…transmitting/receiving performance, with a larger broadband frequency than any other piezoelectric materials. An advantage of the composite material is that it is capable of wave cancellation over a large frequency range underwater [10][11][12]. In an acoustic absorber system with a single sensor, a common transmission path for both incident and reflected waves renders the separate analysis of the two types of waves difficult.…”

“…The smart skin shows higher echo reduction performance compared with other acoustic absorber systems. The multi-sensor system can separate superposed signals by using a time-delay signal separation method [10]. Furthermore, this study presents an application of an adaptive control scheme that can enable the multi-sensor system to achieve perfect noise cancelation when environmental changes occur.…”

This paper concerns the use of adaptive wave cancellation in a new multilayer smart skin sensor to attenuate the primary low-frequency noise underwater. The proposed multilayered system is designed with a piezoelectric actuator (Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 composite) and two layers of polyvinylidene fluoride to accelerate wave absorption. Furthermore, the use of a combination of an adaptive control scheme and a time-delay signal separation method has the potential to provide the proposed absorber system with a wave cancellation capability and thereby enable the absorber system to respond to environmental changes underwater. The use of smart piezoelectric materials and an adaptive control approach enables the absorber system to achieve the high attenuation level of the reflected waves, unlike typical absorber systems based on active noise control. Echo reduction experiments showed that the proposed piezoelectric-based multilayer sensor with an adaptive controller could attenuate reflected wave signals effectively.

“…The dielectric properties of PIN-PMN-PT also exhibited minimum dependency on thickness whereas the permittivity of PMN-PT halved at a thickness of 40 μm. DeAngelis et al [27] agreed that PIN-PMN-PT surpassed the performance of PZT where the volume of material could be minimized for the same impedance. To be a good substitute for PZT, there is a need for adequate design guidelines to explore this material further.…”

In the past decade, there has been rapid development in piezoelectric energy harvester due to its limited application and low output power. This paper critically reviews the strategies implemented to improve the power density for low-frequency applications. These strategies include piezoelectric material selection as well as optimisations of shape, size and structure. The review also focuses on the recent advances in multi-modal, nonlinear and multi-directional energy harvesting. Based on the comprehensive summary of the normalised power density at 1g acceleration, it was found that most works fell in the second quadrant of low frequency and high power density. The maximum value was around 1mW/mm3 /g. Adding an extension of beam or spring to the conventional piezoelectric beam could enhance the normalised power density dramatically. Additionally, the multi-modal energy harvester exhibits broader bandwidth when its multiple resonance peaks get closer. The findings indicate that the anticipated performance of a piezoelectric harvester can be attained by achieving the trade-off between output power and bandwidth. To achieve high performance at low frequency, the following factors are essential: excellent material characteristics optimised geometry for high strain energy density, excellent flexibility, high excitation amplitude and broad bandwidth.
