A Real-Time Electronic System for Measuring Dynamic Knee Circumference

Therapeutic monitoring devices for joint inflammation remain limited due to the difficulty of accurately measuring anatomical structures, such as the knee, in motion. Having the capacity to obtain measurements of physical symptoms, such as swelling, enhances the analysis by both therapeutic practitioners and physicians managing post-surgical cases. The goal of this project is to design and prototype an electronic device that incorporates stretch sensor technology embedded in a sleeve. The sleeve wraps a knee or elbow joint and provides accurate measurements of joint circumference while allowing the user to wear it during physical activities. A key fabrication goal is to utilize flexible PCB technology to fully embed the system into the sleeve. This eliminates the need for multiple external devices, enabling unencumbered movement for the patient.
