Powered exoskeleton
A wearable mechanical system that uses motors, sensors, controls, and a power source to add torque or support motion at one or more joints. Consumer models commonly assist the hips or knees; clinical and industrial devices are separate categories with different evidence and safety requirements.
Why it matters
The word exoskeleton covers radically different products. Identifying the assisted joint, intended use, and regulatory category prevents an outdoor walking aid from being confused with a rehabilitation or workplace device.
