美国政府问责局（GAO）：2025年可穿戴技术：制造和仓储领域的潜在机遇和部署挑战报告（英文版）

Ergonomic sensors are designed to detect postures or motions that could cause injury. Ergonomic sensor manufacturers have self-reported case studies with improved safety outcomes. GAO, however, found limited evidence that current ergonomic sensors improve worker safety, in part because multiple factors contribute to musculoskeletal injuries and posture measurements alone may not accurately predict risk.
