Wearable Sensor

A small electronic device worn on the body that continuously collects data about the wearer's movements, physiological state, or environment. In accessibility and rehabilitation contexts, wearable sensors such as accelerometers, gyroscopes, and inertial measurement units can monitor gait patterns, detect falls, track physical activity, and provide biofeedback. Wearable sensors offer advantages over laboratory-based measurement systems by enabling data collection in real-world settings, though challenges include user comfort, sensor placement consistency, and data processing complexity.
