Recent advances in wearable energy harvesting technology as solutions to occupational health and safety programs are presented. Workers are often exposed to harmful conditions-especially in the mining and construction industries-where chronic health issues can emerge over time. While wearable sensors technology can aid in early detection and long-term exposure tracking, powering them and the associated risks are often an impediment for their widespread use, such as the need for frequent charging and battery safety. Repetitive vibration exposure is one such hazard, e.g., whole body vibration, yet it can also provide parasitic energy that can be harvested to power wearable sensors and overcome the battery limitations. This review can critically analyze the vibration effect on workers' health, the limitations of currently available devices, explore new options for powering different personal protective equipment devices, and discuss opportunities and directions for future research. The recent progress in self-powered vibration sensors and systems from the perspective of the underlying materials, applications, and fabrication techniques is reviewed. Lastly, the challenges and perspectives are discussed for reference to the researchers who are interested in self-powered vibration sensors.

“…On the other hand, due to more brittle nature of the most structural composites in comparison with metals, they are more vulnerable to internal defects. There are several structural health monitoring methods that are proposed to be employed in FRP structures, including: vibration based sensors, embedded optical and piezoelectric sensors, acoustic emission, and Lamb wave method 118 . For an FRP bogie or car body structure, embedded sensors can be employed for online health monitoring during their working time.…”

The application of fiber‐reinforced polymer (FRP) composite materials and structures in various industrial sectors is expanding significantly to meet the rising demand for efficient, reliable, and functional building materials. Using FRPs can be an excellent strategy for enhancing railway structures and equipment because of their high strength‐to‐weight ratio, tailorable mechanical properties, and suitable long‐term characteristics. However, the railway industry appears to be hesitant to adopt composite materials compared to other transportation sectors like aerospace. It seems that there is still a long way to go before FRPs reach their full potential in railway applications. The goal of the current study is to explore the current uses of FRPs in the railway industry and the significant challenges, obstacles and difficulties that must be overcome to put FRP‐based concepts into practice for structural and rail vehicle applications.Highlights Applications of FRPs in railway vehicles and rail lines are reviewed. Main challenges for utilization of FRP in railway industry are studied. Future trends and applications of FRPs in the railway sector are introduced.

“…SHM has been employed in the monitoring of almost every engineered structure, from rotating machinery [2,3] to bridges and buildings [4,5]. This technique includes various damage detection methods, namely vibration-based sensors, embedded sensors, acoustic emissions, lamb wave method, and comparative vacuum monitoring [6]. Humans and the environment largely influence the health of these structures and, with time, damage can arise in these structures which can be attributed to aging, inadequate service conditions, and erroneous manufacturing.…”

Throughout service, damage can arise in the structure of buildings; hence, their dynamic testing becomes essential to verify that such buildings possess sufficient strength to withstand disturbances, particularly in the event of an earthquake. Dynamic testing, being uneconomical, requires proof of concept; for this, a model of a structure can be dynamically tested, and the results are used to update its finite element model. This can be used for damage detection in the prototype and aids in predicting its behavior during an earthquake. In this instance, a wireless MEMS accelerometer was used, which can measure the vibration signals emanating from the building and transfer these signals to a remote workstation. The base of the structure is excited using a shaking table to induce an earthquake-like situation. Four natural frequencies have been considered and six different types of damage conditions have been identified in this work. For each damage condition, the experimental responses are measured and the finite element model is updated using the Berman and Nagy method. It is seen that the updated models can predict the dynamic responses of the building accurately. Thus, depending on these responses, the damage condition can be identified by using the updated finite element models.
