A Sensor to measure electric vector fields based on the Pockel effect and a sensor making good use of a search capacitor have been submitted to the same electric field excitations. Outputs of their analog electronics are further processed using a multi-channel dynamic signal analyzer (24 bits and 10 mHz to 100 kHz analysis bandwidth). Both AC and DC behavior have been addressed, the later with the help of an electric field mill. The direct comparison was made possible up to 100 kVm−1 using a large enough electric field source and high voltage outputs amplifiers. This way, the sensors are operated at the same time, while occupying similar positions inside the electric field. Results expressed as a voltage transfer function in the AC mode exhibit a good coherence all along the analysis band. It highlights the different bandwidth of the two instruments nonetheless sharing three decades: the search capacitor working at low frequency while the electro-optic one is known to work at high frequency. Finally, the electric field mill used at a chopping frequency of 54 Hz induces a limitation for both sensors in the lower part of their measuring range, below a few hundreds of Vm−1, while noise floors of each sensor are found well below a residual signal induced by the electric field mill rotation.

The Internet of Things (IoT) is a fast-emerging technology which aims to address the societal challenges faced by the modern cities. IoT can be underpinned in a wide range of Smart City applications including (but not limited to) holistic urban planning, tracking of city wide services, enhancing public transportation, while reducing traffic congestion, keeping citizens safe, enabling sustainable economic growth, and improving quality of life of citizens. IoT has been growing rapidly in different domains, which led to the development of numerous IoT platforms, standards, and protocols, etc. Today, within a Smart City, different types of IoT systems and applications are deployed which operate independently. There is a need to enable city authorities and application developers to see IoT systems as part of an integrated whole, allowing optimal use of existing infrastructure and achieving more than what these independent systems can do in isolation. Furthermore, with the arrival of European Union’s General Data Protection Regulation (GDPR), the governance of diverse IoT resources has become a critical requirement. This paper presents a smart governance methodology designed for managing heterogeneous IoT systems. The proposed approach facilitates the semantic interoperability of IoT infrastructure deployed across various domains in Smart Cities and enables integrated governance (and management) of IoT systems and their resources.

This paper proposes to optimize the operating frequency band of a lab on a chip, based on bio-impedance spectroscopy for single cell. Bio-impedance allows to characterize low cells concentration or single cell by providing an electrical signature. Thus, it is necessary to perform impedance measurements up to several tens of mega-Hertz in order to extract the internal cell signature. In the case of a single cell, characterization is performed in a very small volume down to 1 pL. In the same time measured impedances increase up to hundreds of kilo-ohms. At frequencies above mega-Hertz, parasitic effects such as coupling capacitances could prevail over sample impedance and completely short-circuit it. To optimize the pass band, a complete model of a cytometric device was developed including coupling capacitances as a function of chosen materials. Simulation results prove the ability to increase the high frequency simply by optimizing track geometries and placement. This is done without any change of the sensing structure (microelectrodes design and microchannel). This assumption was obtained by measuring and comparing parasitic effects of our first sensors and the new optimized ones. Decrease of coupling capacitance by a factor higher than 10 was obtained allowing to perform characterizations in a wide frequency band.

There are many forest problems that need to be solved to move toward a sustainable society; therefore, educating people, especially children, about forest problems is very important. Although schools conventionally educate children through textbooks, children are not expected to learn about forest problems actively from only textbooks. Therefore, this study develops game-type learning material that enables students learn complex mechanisms of vegetation succession and the actual state of succession, while taking interest in forest problems, by performing forest management themselves. For evaluation of the system, we measure the electrodermal activity (EDA) because using a conventional questionnaire can only qualitatively evaluate whether learning using the system is more interesting than when using text. EDA sensors are used to measure physiological response of participants reading texts and those using the system; the interest when using the system is evaluated quantitatively. The experiment shows that the change of EDA increases when using the system, which suggests that using the system is more interesting and can be better for learning than reading text.

Surf is an increasingly popular sport, with its evaluation being mostly qualitative and subjective. Surf analysis is often performed with commercially available systems. However, most of them are based on Global Positioning System (GPS) data and/or seem to lack in the precision and validity that surf practitioners need. Thus, a novel and accurate method to detect and characterize all surf-related events during a surf session is presented, recurring to commonly available sensors present in smartphones. Identification and characterization of stationary events, such as sitting or lying when waiting for a wave, paddle and wave riding during a whole surf session was assessed recurring to inertial data alone, GPS data alone or a combination of both. The most accurate results were obtained using a combination of both sources of data with an overall event detection accuracy of 95%, encompassing all aforementioned events. In particular, wave detection showed quite promising results with 97% for both precision and recall. These findings may indicate that the proposed solution may be suitable for the creation of a precise and valid surfer performance monitor system that could be used in real-time, providing important feedback to surf practitioners.

This paper evaluates the sensing performance of photodetector in response to different colours of light sources used for water turbidity measurement. Initially the best photodetector is chosen based on the voltage variation during ON/OFF condition. Once the photodetector is selected, a complete system is developed by implementing LABVIEW as a processing tool. Five samples of water with different turbidity were prepared and tested using different colours of LEDs. With respect to the actual values of the sample, the performances of the sensing system were evaluated. In terms of accuracy, White LED gives the best performance with less than 10% difference in most measurement and followed by UV LED. Meanwhile for precision, UV has the best performance as most of the measurement gives standard deviation of less than 1 and followed by White LED. Therefore the use of both colours are found to be suitable for water turbidity measurement ranging from 0 to 1000 NTU.

For smart grids, suitable communication technologies and routing algorithms are very important in data transmission. Among various data transmission technologies, LoRa is an Internet of Things (IoT)-based wireless communication technology, characterized by its long communication distance up to a few kilometers and low power consumption. Therefore, LoRa is an appropriate candidate for data transmission in smart grids. In this study, the performance of a LoRa device is examined. Based on the experimental results, a routing algorithm that uses the AODV is developed for the LoRa device, and the algorithm enables a long-chain topology suitable for data transmission in a smart grid. A multi-hop mechanism is simulated to ensure a high final receiving rate of packets, by finding the optimal path with the least number of hops in the transmission topology for a power transmission line. The simulation results show a great performance of the proposed algorithm in long distance transmission.

Multi-modal sensor networks are used in various fields of application to allow for highly-automated and autonomous systems. Due to the increasing number of sensors and overall system complexity, we propose the use of Virtual Testbeds (VTBs) which allow for comprehensive virtual system tests throughout the development process. Here, VTBs are used as a software environment in which “Digital Twins” of real technical systems are modeled and simulated within their operational environment. In this contribution, we describe a highly-scalable sensor framework used by those VTBs to enable efficient physically-based simulations of various sensor types (e.g. camera, LiDAR, RADAR and ultrasonic sensors). In this context, we present generalized sensor structures that are acting on the same data base to reduce redundancy and ensure consistency across different sensor types and manufacturers. Furthermore, those highly-scalable sensor structures are combined with modern GPUs to achieve efficient and interactive simulations of sensor-enabled applications from various domains.

Radiofrequency method for measurement of interface position between two substances that are liquids with different densities in particular, located in a tank one above the other is considered. Measurement results are independent on electromagnetic parameters of both one and two substances. The method is realized via application of two or three TEM transmission line sections correspondingly and joint functional processing of their resonant frequencies. The line sections have horizontal parts at their lower ends.
