【 摘 要 】

Sensors, which can be integrated into clothing and used to measure biochemical changes in body fluids, Such as sweat, constitute a major advancement in the area of wearable sensors. Initial applications for Such technology exist in personal health and sports performance monitoring. However, sample collection is a complicated matter as analysis must be done in real-time in order to obtain a useful examination of its composition. This work Outlines the development of a textile-based fluid handling platform which uses a passive pump to gather sweat and move it through a pre-defined channel for analysis. The system is tested both in vitro and in vivo. In addition, a pH sensor, which depends on the use of a pH sensitive dye and paired emitter-detector LEDs to measure colour changes, has been developed. In vitro and on-body trials have shown that the sensor has the potential to record real-time variations in sweat during exercise. (C) 2009 Elsevier B.V. All rights reserved.
