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.

“…[57][58][59][60] Recent applications of IPMC sensing capabilities span the measurement of force, flow, shear loading, curvature, structural health monitoring and energy harvesting. [61][62][63][64][65][66][67][68][69] IPMCs generate charges when experiencing a mechanical load or deformation. If the polymer is not deformed, the distribution of cations inside the polymer is uniform and no output voltage is detected.…”

In this paper, the authors present a comprehensive review of ionic polymer-metal composites (IPMCs) covering their fundamentals, fabrication processes, characterization and applications. IPMCs are becoming increasingly popular among scholars, engineers and scientists due to their inherent properties of low activation voltage, large bending strain -that is, the transformation of electrical energy to mechanical energy -and properties to be used as a bidirectional material -that is, they can be used as actuators and sensors. Among the diversity of electroactive

“…With the exception of the hot-wire array presented by Yang et al [28], biomimetic approaches picked up fluid motion by means of a flow-induced deflection of a cantilever-like or lamella-shaped structure (an artificial cupula), which was detected by piezo-electric [38], resistive [39][40][41][42][43], capacitive [44][45][46], ionic polymer-metal composite (IPMC)-based [29,47] or optical [48][49][50][51] read-out techniques.…”

“…The capacitive detection principle was also used to fabricate bioinspired sensors based on fish SNs that contained an SU-8 hair cell [46,62]. Some flow sensors are based on the piezo-electric or depolarization detection principle [47,[63][64][65][66]. These hair cell-inspired sensors were made from ionic polymer-metal composites (IPMCs).…”

Micro-Machined Flow Sensors Mimicking Lateral Line Canal Neuromasts

et al. 2015

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.
