“…Researchers have developed ALLFS for underwater hydrodynamic field measurement, and they hope to achieve the artificial counterparts with similar performance of aquatic animals. For detection of underwater flow measurement, a lot of ALLFS are designed and fabricated, Such as AFFLS canal system (Yang et al 2011a, b), a Stress-driven cantilever-based flow sensor (Qualtieri et al 2011) and so on.…”

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.

“…Unfortunately, the above structures are very fragile and suffer from non-uniformity during fabrication. Qualtieri et al [54,55] introduced a waterproof system mimicking SNs that was also based on a piezo-resistive detection principle. Their self-binding cantilevers consisted of Si, SiO 2 , SiN 4 or aluminum nitride.…”

Micro-Machined Flow Sensors Mimicking Lateral Line Canal Neuromasts

Fish sense water motions with their lateral line.The lateral line is a sensory system that contains up to several thousand mechanoreceptors, called neuromasts. Neuromasts occur freestanding on the skin and in subepidermal canals. We developed arrays of flow sensors based on lateral line canal neuromasts using a biomimetic approach. Each flow sensor was equipped with a PDMS (polydimethylsiloxane) lamella integrated into a canal system by means of thick-and thin-film technology. Our artificial lateral line system can estimate bulk flow velocity from the spatio-temporal propagation of flow fluctuations. Based on the modular sensor design, we were able to detect flow rates in an industrial application of tap water flow metering. Our sensory system withstood water pressures of up to six bar. We used finite element modeling to study the fluid flow inside the canal system and how this flow depends on canal dimensions. In a second set of experiments, we separated the flow sensors from the main stream by means of a flexible membrane. Nevertheless, these biomimetic neuromasts were still able to sense flow fluctuations. Fluid separation is a prerequisite for flow measurements in medical and pharmaceutical applications.

“…Other artificial cilia are based on the piezoelectric effect, for example, with polyvinylidene fluoride fibers (PVDF) (Li et al 2010). The sensors are either used as surface neuromasts (Liu 2007;Hsieh et al 2011;Qualtieri et al 2011), or integrated in a canal Klein et al , 2013. Both approaches can in principle be used for dipole localisation (Nguyen et al 2011;Yang et al 2011).…”

In this work we present Snookie, an autonomous underwater vehicle with an artificial lateral-line system. Integration of the artificial lateral-line system with other sensory modalities is to enable the robot to perform behaviors as observed in fish, such as obstacle detection and geometrical-shape reconstruction by means of hydrodynamic images. The present chapter consists of three sections devoted to design of the robot, its lateral-line system, and processing of the ensuing flowsensory data. The artificial lateral-line system of Snookie is presented in detail, together with a simple version of a flow reconstruction algorithm applicable to both the artificial lateral-line system and, e.g. the blind Mexican cave fish. More in particular, the first section deals with the development of the autonomous underwater vehicle Snookie, which provides the functionality and is tailored to the requirements of the artificial lateral-line system. The second section is devoted to the implementation of the artificial lateral-line system that consists of an array of hot thermistor anemometers to be integrated in the nozzle. In the final section, the information processing ensuing from the flow sensors and leading to conclusions about the environment is presented. The measurement of the tangential velocities at the artificial lateral-line system together with the no-penetration condition provides
