“…For example, some researchers adopted piezoresistive principle to design vector hydrophone (Zhang et al 2008;Xue et al 2007). Other researchers focused on flow measurement in air (Ozaki et al 2000;Wang et al 2007;Song et al 2011), although not for underwater applications, they also have the potential to be redesigned for underwater applications.…”

on. However, there are limitations of these technologies. For example, acoustic sensor suffers from scattering and multipath propagation issues. Optic sensor cannot propagate well in water and is limited by the turbidity of the sea water. Both sensors are not suitable for forming distributed arrays. Because of these limitations, many researchers are trying to study some new alternative sensors which are inspired from biological sensing abilities, such as lateral line organ of fish. Fishes live in a fluid environment, therefore it is not surprising that fishes have developed abilities which affect numerous aspects of behaviors including maneuvering in complex fluid environments (Van Trump and McHenry 2008; Mogdans and Bleckmann 2012), schooling (Pitcher et al. 1976), prey tracking (Pohlmann et al. 2004), rheotaxis (Gardiner and Atema 2007), courtship and communication (Coombs and Braun 2003). It is known that the lateral line is a critical component of the fish sensory system and found in most fishes and some other aquatic organisms. For example, Mexican blind fish relies on the lateral line system to navigate. The lateral line plays an important role in many behaviors by providing hydrodynamic information about the surrounding fluid. The fishes use lateral line sensors to monitor surrounding flow field for maneuvering and survival underwater. This is why researchers have developed ALLFS for underwater flow sensing applications.In the following, this paper surveys the works done in investigating morphology and biophysics of the lateral line of fish, such as theoretical models of the lateral line of fish which are foundation for design ALLFS for underwater flow sensing. Also, this paper reviews the status of ALLFS and underwater applications. Finally, this paper intends to discuss the existing problems and the future trends of ALLFS.Abstract Biomimetics is a promising field of research in which natural processes and structures are transferred to technical applications. The lateral line is a critical component of the fish sensory system and plays an important role in many behaviors by providing hydrodynamic information about the surrounding fluid. It is believed that the artificial lateral line flow sensors (ALLFS) are advantageous for underwater applications. This paper reviews the morphology and biophysics of the lateral line, especially theoretical models of lateral line, including biomechanical model, frequency response and time domain response of lateral line. Also, this paper reviews some efforts to mimic lateral line system in recent years. In order to capture the recent research status, this paper reviews the design and fabrication of ALLFS based on different sensing principles. Further researches to develop ALLFS and their underwater applications are also discussed in this paper.

“…Water flow rate and direction can be accurately detected using these sensory hair cells. Such sensors can be mainly classified based on sensing method into piezoresistive effect [9,10], piezoelectric effect [11,12], capacitive principle [13][14][15][16], and ionic polymer-metal composites (IPMC) [17][18][19][20]. Two main factors that play a pivotal role in efficient flow biosensors are high sensitivity and resolution.…”

This paper suggests development of a flexible, lightweight, and ultra-sensitive piezoresistive flow sensor based on vertical graphene nanosheets (VGNs) with a mazelike structure. The sensor was thoroughly characterized for steady-state and oscillatory water flow monitoring applications. The results demonstrated a high sensitivity (103.91 mV (mm/s)−1) and a very low-velocity detection threshold (1.127 mm s−1) in steady-state flow monitoring. As one of many potential applications, we demonstrated that the proposed VGNs/PDMS flow sensor can closely mimic the vestibular hair cell sensors housed inside the semicircular canals (SCCs). As a proof of concept, magnetic resonance imaging of the human inner ear was conducted to measure the dimensions of the SCCs and to develop a 3D printed lateral semicircular canal (LSCC). The sensor was embedded into the artificial LSCC and tested for various physiological movements. The obtained results indicate that the flow sensor is able to distinguish minute changes in the rotational axis physical geometry, frequency, and amplitude. The success of this study paves the way for extending this technology not only to vestibular organ prosthesis but also to other applications such as blood/urine flow monitoring, intravenous therapy (IV), water leakage monitoring, and unmanned underwater robots through incorporation of the appropriate packaging of devices.

This paper reports on recent developments to improve the performance of hair vector hydrophone by means of several technological advancements in the fabrication procedures and corresponding sensor design. With fish's lateral line organs as prototypes, NEMS (Nano-Electromechanical System) vector hydrophone with directivity has been designed. This paper describes the meso-piezoresistance effect of resonant tunneling thin-film, and the NEMS hydrophone based on this effect is highly sensitive and small size. The application of bionics structure may improve the low-frequency sensitivity of hydrophone. The calibration test shows that NEMS vector hydrophone's receiving sensitivity is up to -170 dB (0dB = 1 V/lPa), has a good directional pattern in the form of ''8'' shape. The sea test shows that the direction of target can be detected by single NEMS vector hydrophone. In the anechoic tank, it has been verified that NEMS vector hydrophone can track the trajectory of the moving target.
