TL;DR

The results indicate that the intelligent trousers system provides a feasible solution for integrating wearable sensing, motion analysis, and real-time intervention into everyday garments, offering a promising platform for long-term lower-limb health monitoring and preventive applications.

Abstract

Continuous monitoring of unconscious lower-limb behaviors, such as leg crossing and shaking, is vital for preventing musculoskeletal disorders. This paper presents a smart trousers system integrating screen-printed flexible pressure sensors and IMUs for real-time intervention. Unlike generic trackers, this system utilizes a multi-sensor fusion algorithm based on Zero-Crossing Rate (ZCR) and biomechanical thresholds to accurately detect specific maladaptive postures. Upon detection, dual-modal feedback (auditory/haptic) is triggered to disrupt the habit. A 10-day study demonstrates that the system significantly reduces behavior frequency during the intervention phase and promotes habit retention in the subsequent non-intervention phase. The results indicate that the intelligent trousers system provides a feasible solution for integrating wearable sensing, motion analysis, and real-time intervention into everyday garments, offering a promising platform for long-term lower-limb health monitoring and preventive applications.

Intent-Synchronized Continuous Forearm Prosthesis Control using Skin Deformation and IMU Sensors

Conventional surface electromyography (sEMG)based prostheses often rely on discrete pattern classification, which forces users into unnatural, disjointed, and sequential joint actuation. To address this limitation, this study proposes a novel, intuitive control system for forearm prostheses that enables simultaneous, c...
