 Recently, advancements in wearable energy harvesting technology have been made to address occupational health and safety concerns. In particular, vibrations generated by workplace activities can be used to power wearable sensors, thus eliminating the need for frequent charging or battery replacement. This review examines the potential benefits of this approach, including its ability to detect chronic health issues before they become serious, reduce the risk of worker injury due to repetitive motion, and increase the accuracy of data collection. Additionally, it explores the limitations of current devices, as well as opportunities and directions for future research.
