Special Issue Information

Dear Colleagues,

Structural health monitoring (SHM) using wireless sensor networks (WSNs) has attracted great attention in recent years due to its ability to reduce the costs of installation and maintenance for SHM systems. WSNs have been employed to monitor critical infrastructure such as bridges, buildings, dams, ships, and aircraft, and have the potential to improve structure lifespan as well as public safety. Wireless sensor networks can sense vibration, pressure, temperature etc. and transmit the sensed data through a wireless medium; they can play a key role in structural health monitoring. Technologies such as Internet of things (IoT) and artificial intelligence (AI) incorporated with wireless networks have made the monitoring of structural health simple and effective. WSNs consist of three main features: (1) a sensing technology (e.g., accelerometer, strain sensor, optical fiber sensor), (2) wireless communication such as (e.g., Wi-Fi, Bluetooth), and (3) data processing (e.g., centralized, local, or cluster-based processing). WSNs for SHM introduce challenges in network design including scalability, time synchronization, sensor placement, and data processing. Recent studies have demonstrated the potential applications of WSNs in monitoring large-scale civil infrastructure. However, improvements to the power consumption and long-term reliability of WSNs represent great challenges.

Abstract
Ultrasonic communication and power transfer are attractive solutions when conventional electromagnetic-based or wired connections are unfeasible. Most ultrasonic communication applications concern a single-solid barrier.

Ultrasonic communication and power transfer are attractive solutions when conventional electromagnetic-based or wired connections are unfeasible. Most ultrasonic communication applications concern a single-solid barrier. Nevertheless, some relevant scenarios can be composed of several fluid—solid media, through which communication and power transfer are intended. Due to its multi-layer nature, insertion loss and, consequently, the system efficiency considerably decrease. This paper presents an ultrasonic system capable of simultaneously power transferring and transmitting data through a set of two flat steel plates separated by a fluid layer using a pair of co-axially aligned piezoelectric transducers on opposite sides of the barrier. The system is based on frequency modulation and adopts a novel technique for automatic gain and automatic carrier control. The modems used herein were developed specifically for this application, rendering the system able to transfer data at a rate of 19,200 bps, using the frequency shift keying (FSK) modulation scheme and simultaneously transferring 66 mW of power through two flat steel plates (5 mm) separated by a fluid layer (100 mm), which completely supplied a pressure and temperature sensor. The proposed automatic gain control allowed a higher data transmission rate and the automatic carrier control reduced power consumption. The former reduced the transmission error from 12% to 5%, while the latter reduced the global power consumption from 2.6 W to 1.2 W. The proposed system is promising for monitoring applications such as oil wellbore structural health monitoring systems. Full article

Structural damage detection using inclinometers is getting wide attention from researchers. However, the high price of inclinometers limits this system to unique structures with a relatively high structural health monitoring (SHM) budget. This paper presents a novel low-cost inclinometer, the low-cost adaptable reliable angle-meter (LARA), which combines five gyroscopes and five accelerometers to measure inclination. LARA incorporates Internet of Things (IoT)-based microcontroller technology enabling wireless data streaming and free commercial software for data acquisition. This paper investigates the accuracy, resolution, Allan variance and standard deviation of LARA produced with a different number of combined circuits, including an accelerometer and a gyroscope. To validate the accuracy and resolution of the developed device, its results are compared with those obtained by numerical slope calculations and a commercial inclinometer (HI-INC) in laboratory conditions. The results of a load test experiment on a simple beam model show the high accuracy of LARA (0.003 degrees). The affordability and high accuracy of LARA make it applicable for structural damage detection on bridges using inclinometers. Full article
