  The workplace influences the safety, health, and productivity of workers at
multiple levels. To protect and promote total worker health, smart hardware,
and software tools have emerged for the identification, elimination,
substitution, and control of occupational hazards. Wearable devices enable
constant monitoring of individual workers and the environment, whereas
connected worker solutions provide contextual information and decision support.
Here, the recent trends in commercial workplace technologies to monitor and
manage occupational risks, injuries, accidents, and diseases are reviewed.
Workplace safety wearables for safe lifting, ergonomics, hazard identification,
sleep monitoring, fatigue management, and heat and cold stress are discussed.
Examples of workplace productivity wearables for asset tracking, augmented
reality, gesture and motion control, brain wave sensing, and work stress
management are given. Workplace health wearables designed for work-related
musculoskeletal disorders, functional movement disorders, respiratory hazards,
cardiovascular health, outdoor sun exposure, and continuous glucose monitoring
are shown. Connected worker platforms are discussed with information about the
architecture, system modules, intelligent operations, and industry
applications. Predictive analytics provide contextual information about
occupational safety risks, resource allocation, equipment failure, and
predictive maintenance. Altogether, these examples highlight the ground-level
benefits of real-time visibility about frontline workers, work environment,
distributed assets, workforce efficiency, and safety compliance
