“…In this context, assembled graphene‐based films can be easily deposited and patterned onto low‐cost substrates and integrated into flexible composite materials for monitoring localized strain. They can also act as embedded sensors in structural components such as fiber‐reinforced polymer composites and used as passive RFID tags . The desirable properties of these sensors are wireless, highly flexible, and nonintrusive, while requiring very low power and cost–effectiveness.…”

Development of next-generation sensor devices is gaining tremendous attention in both academia and industry because of their broad applications in manufacturing processes, food and environment control, medicine, disease diagnostics, security and defense, aerospace, and so forth. Current challenges include the development of low-cost, ultrahigh, and user-friendly sensors, which have high selectivity, fast response and recovery times, and small dimensions. The critical demands of these new sensors are typically associated with advanced nanoscale sensing materials. Among them, graphene and its derivatives have demonstrated the ideal properties to overcome these challenges and have merged as one of the most popular sensing platforms for diverse applications. A broad range of graphene assemblies with different architectures, morphologies, and scales (from nano-, micro-, to macrosize) have been explored in recent years for designing new high-performing sensing devices. Herein, this study presents and discusses recent advances in synthesis strategies of assembled graphene-based superstructures of 1D, 2D, and 3D macroscopic shapes in the forms of fibers, thin films, and foams/aerogels. The fabricated state-of-the-art applications of these materials in gas and vapor, biomedical, piezoresistive strain and pressure, heavy metal ion, and temperature sensors are also systematically reviewed and discussed, and their sensing performance is compared.

“…For safety‐critical structures, it is important that there is a high probability of timely detection of any cracks throughout the operational life of the structures . For example, composites are vulnerable under impact damages . Life of structures needs to be maximized by ensuring their health and safety before reaching a critical state.…”

Summary Various types of wireless sensor systems are used for structural health monitoring. Especially, chipless wireless sensors are useful in harsh environmental conditions of high temperature and toxic chemicals. This paper reports a chipless passive structural health monitoring sensor made with frequency‐selective surface (FSS) array for detecting damage location. FSS is a kind of microwave meta‐material antenna that is selective by its electromagnetic characteristics associated with geometrical shape and electrical impedance. An FSS‐array‐based wireless sensor was made on a flexible substrate that can be easily attached to arbitrary structures. When microwaves are applied to the FSS via a single horn antenna, the sensor senses its reflection changes, and by scanning the horn antenna, the location of damage is detected. Design, fabrication, and characterization of cross‐type FSS array are carried out, and a computer simulation is performed for comparison.

“…This paper attempted to develop a fault detection method that uses only the data types being acquired in industrial fields, without the need for any additional sensors. To use (12), the values of internal resistances are required; however, in real-world settings, no sensor can be available to measure these resistances [28]. In this case, it is necessary to perform curve fitting using the proposed linear regression model of (12).…”

Solenoid valves are widely used to control fluid flow in various mechanical systems. If the valves do not function properly, the mechanical systems can lose their ability to control the fluid flow. This paper describes a fault detection method that can monitor coil burnout under dynamic thermal loading. The method consists of three steps. First, an equivalent current model of the solenoid valves is derived from Kirchhoff's voltage law. Then, a predictive regression model is developed to describe the relationship between the electric current and the dynamic change of operating temperature of the valves. Finally, a health indicator of solenoid coil burnout is devised in conjunction with the derived model. To demonstrate the validity of the proposed fault detection method, a case study is presented with solenoid valves taken from real braking systems of urban railway vehicles. The case study confirms that the proposed method can detect the coil burnout independent of the operating temperature. We anticipate that the proposed method can be widely applicable to diagnose any electromagnetic actuator of engineered systems as well as solenoid valves in various industrial applications.
