Aquaculture is presented as a sustainable method to provide fish, although in reality, it is far from being sustainable. Its negative impacts on the environment can be prevented and corrected by the use of sensors, developing precision aquaculture. Sensors are widely used in terrestrial applications, but in underwater environments, their use is constrained by a variety of issues. The aim of this paper is to describe the state-of-art of the underwater sensors for water quality monitoring. First, the requirements and challenges of underwater sensors for aquaculture monitoring are discussed in detail. The main challenges are the need of a waterproof isolation or the need to avoid corrosion and biofouling, among others. Second, there are some advantages compared with terrestrial applications, such as no need of minimized systems or the fact that such systems only require low accuracy. Subsequently, we evaluated the different options available to sense each variable, related to the needs of the aquaculture sensors. For temperature monitoring, thermistors, thermocouples or RTC seem to offer similar advantages. In contrast, for dissolved oxygen monitoring, the optical method seems to be the best option. For turbidity, optical methods are the most employed ones, while for conductivity measurements, the inductive coils are a promising option.

“…Base RFSs demonstrated aquatic environmental stability when adopted in a test flume, with the intent to map out the flux of dissolved chemicals and solids [93] typically under at most 3 m of water [92]. Stability was not recorded with respect to temperature variations to which RFSs are rather extremely sensitive [25], so we should assume they can be adopted as temperature sensors too.…”

Resistive flex sensors can be used to measure bending or flexing with relatively little effort and a relativelylow budget. Their lightness, compactness, robustness, measurement effectiveness and low power consumption make these sensors useful for manifold applications in diverse fields.Here, we provide a comprehensive survey of resistive flex sensors, taking into account their working principles, manufacturing aspects, electrical characteristics and equivalent models, useful front-end conditioning circuitry, and physic-bio-chemical aspects. Particular effort is devoted to reporting on and analyzing several applications of resistive flex sensors, related to the measurement of body position and motion, and to the implementation of artificial devices. In relation to the human body, we consider the utilization of resistive flex sensors for the measurement of physical activity and for the development of interaction/interface devices driven by human gestures. Concerning artificial devices, we deal with applications related to the automotive field, robots, orthosis and prosthesis, musical instruments and measuring tools. The presented literature is collected from different sources, including bibliographic databases, company press releases, patents, master's theses and PhD theses.

We describe a concept of autonomous intelligent and ambient networks suited for disaster scenarios (e.g. pollution leakages, earthquakes or forest fires) where the decisions are made only on the basis of sensed data, without human control. We discuss possible system architectures: its passive component (sensors) that monitors the environment, as well as the active one, i.e. robots or other machines (actuators) that are able to react accordingly to the previously gathered data. We highlight some challenges regarding distributed and self-organizational aspects of these networks. Also, we address an issue of collaboration that should exist between sensors and actuators. The decisions about the actuator operations are made based on previously sensed data, but these operations can also improve the quality of information gathered later. As an example, we present a simulated scenario of a network able to detect and cease a wildland fire. It is shown how the network performance depends on its limited resources and how sensors readings and actuators actions depend on each other.
