Type: conference-paper
Abstract: Joint stiffness affects over 350 million people worldwide, creating demand for intelligent systems for detection and monitoring. Patients with joint stiffness need continuous rehab guided by experts, highlighting the need for tele-rehabilitation. This work presents a flexible, biodegradable, and economical strain sensor for joint stiffness monitoring, fabricated through a simple, cost-effective method. The sensor uses cotton fabric as a substrate and conductive paste from recycled dry-cell electronic waste for electrodes. A modified interdigitated capacitive (MIDC) structure is used, achieving high sensitivity with a GF value of 1006, response and recovery times of 0.38 sec. On-body testing on wrist, knee, and elbow joints yielded a minimum resolution of 5°. The proposed MIDC strain sensor is ideal for joint stiffness monitoring in tele-rehabilitation.
