Development of a Tactile Feedback System for the Guidance of Independent Rehabilitation in Smart Textiles
摘要
Demographic changes and increasing life expectancy in industrialized nations, including Germany, are driving a growing demand for medical rehabilitation, particularly for musculoskeletal injuries and back-related issues related to sedentary lifestyles and an aging population. However, a shortage of specialists often results in suboptimal rehabilitation, leading to higher long-term costs due to secondary illnesses and lost productivity. This work presents the development of a textile-integrated system designed to support independent upper body rehabilitation at home. The system combines conductive yarns, vibration motors, and motion sensors to detect movements and deliver real-time tactile feedback. A comparative analysis of conductive yarns and connection methods identified suitable materials for durable circuit integration. Additionally, the design minimizes sensor interference by optimizing the spatial relationship between vibration motors and IMUs. User testing confirmed the effectiveness of the tactile feedback, with participants rating the system as intuitive and supportive for exercise correction. The modular design ensures ease of use, maintenance, and adaptability for different applications. The developed prototype provides a user-friendly and scalable solution to enhance rehabilitation outcomes and reduce dependence on constant therapist supervision.
