"Developing Textile Biofeedback Technology: From Bouncing Breasts to Noisy Knees" - Professor Julie Steele

Wednesday 23rd November 2005, 14.G01 (12:30-1:30pm)

A perpetual challenge confronting practitioners when they are evaluating and modifying human motion is to monitor characteristics of human performance in the field and then to "feed" this information back to the performer in real-time so the performer can modify their motion to achieve the desired outcome.
Although advances in technology have provided highly sophisticated equipment for biomechanical analyses of human performance, many of these items are unsuitable as biofeedback devices because they require extensive data processing before meaningful information can be relayed back to the performer.

Recent advances in polymer science, however, now enable inherently conducting polymers to be integrated into appropriate host fabrics, creating the opportunity to develop wearable sensors which offer novel biomonitoring options. These fabric sensors, with strain gauge-like properties that have a wide dynamic range, are ideal for biomonitoring applications as they can be integrated directly into existing clothing and equipment without changing the material properties or functions of these items and without interfering with normal human motion.

When connected to appropriate electronic circuitry, these fabric sensors can also act as unique wearable systems capable of providing biofeedback to the wearer with respect to their joint motion.

The purpose of this talk is to overview the development of these unique fabric sensors, from their initial application in monitoring breast motion to the development of an innovative fabric biofeedback system designed for use in landing training programs to reduce the rate of non-contact anterior cruciate ligament (ACL) ruptures. Future applications of fabric biofeedback systems in enhancing patient rehabilitation following total knee replacement surgery will also be presented.
