Special Issue Information

Dear Colleagues,

Civil infrastructures are often subject to adverse factors such as aging, corrosion, vibration, and impact, which often result in structural damages, such as cracks, loss of stiffness, and reduced bearing capacity, and even structural failure if the early damages are not detected. Structural health monitoring (SHM) provides real-time information regarding any alternations in the structural safety state using onboard sensors. The application of the SHM system to civil engineering structures not only guarantees the safety and integrity of a structure at reduced maintenance costs but also provides theoretical guidance for further research and design. In this field, the invention of various sensors has been a developing studied and practiced topic with encouraging results. New and improved sensors have been developed, along with wireless technology, to provide accurate and highly efficient measurements and assist the monitoring process. This special issue aims to feature the state-of-the-art in technology and methods regarding innovative sensing technologies and their applications. Topics include, but are not limited to, the design of sensors, sensor demodulation technology, signal processing in sensor systems, signal transmission of sensors, and sensor technology and application, among others.

Modern infrastructure heavily relies on robust concrete structures, underscoring the critical need for effective monitoring to ensure their safety and durability. This paper addresses this imperative issue by introducing an innovative automated and wireless system for continuous structural monitoring. By employing embedded electrical resistivity sensors coupled with a wireless-based data transmission mechanism, real-time data collection becomes feasible. We provide a general description of the system’s architecture and its application in a pilot study covering the effects of the devices on concrete properties and data transmission. The dielectric properties of concrete specimens were investigated under natural and accelerated curing/degradation and the results were used in the final design of the antenna device. Furthermore, a pilot test comprising four reinforced concrete columns was used to investigate the range of data transmission from inside to outside of the concrete, the effects of the hardware device on the compressive strength and concrete distribution in the columns, and the data transmission quality in real time under realistic exposure conditions.

Concrete is a widely used construction material, demanding strict quality control to maintain its integrity. The durability and lifespan of concrete structures rely heavily, amongst other factors, on the characteristics of fresh and early age concrete, which are strongly dependent on the curing process. To ensure long-term durability, it is crucial to assess concrete properties throughout construction and verify compliance with design specifications. Currently, electrical resistivity-based sensors are available and used for quality control and monitoring, however, these sensors tend to be costly or only measure at a single location within the concrete cover. This study introduces a printed circuit board (PCB)-based array of electrodes capable of measuring concrete resistivity profiles across the concrete cover, from its fresh state to early age development. In this work, the feasibility of such resistivity PCB-sensors, novel for concrete, is evaluated under laboratory conditions. The sensors exhibit a promising performance in monitoring the efficiency of concrete curing under various conditions. Additionally, they successfully evaluate the effectiveness of internal curing (in our study, promoted by superabsorbent polymers) during the initial stages of hardening. This sensor array provides a valuable tool for monitoring the curing of concrete at early age, and showcases a preliminary solution that could be further developed to ensure long-term performance of concrete infrastructure.
