The construction industry is one of the most physically demanding sectors, posing significant challenges for ageing workers due to declining physical strength, slower reflexes, and increased susceptibility to workplace injuries. The integration of smart wearable technology provides an innovative solution to mitigate these challenges by enhancing safety, monitoring health metrics, and optimizing productivity. Smart wearables, including exoskeletons, biometric sensors, smart helmets, AR glasses, and smart vests, offer real-time monitoring, injury prevention, and efficiency enhancements through data-driven insights. This paper explores their adoption in construction, analyzing benefits, challenges, and future potential through case studies, surveys, and statistical analyses. The findings emphasize the need for broader adoption and policy support.
