Abstract-Textile-based sensors offer an unobtrusive method of continually monitoring physiological parameters during daily activities. Chemical analysis of body fluids, noninvasively, is a novel and exciting area of personalized wearable healthcare systems. BIOTEX was an EU-funded project that aimed to develop textile sensors to measure physiological parameters and the chemical composition of body fluids, with a particular interest in sweat. A wearable sensing system has been developed that integrates a textile-based fluid handling system for sample collection and transport with a number of sensors including sodium, conductivity, and pH sensors. Sensors for sweat rate, ECG, respiration, and blood oxygenation were also developed. For the first time, it has been possible to monitor a number of physiological parameters together with sweat composition in real time. This has been carried out via a network of wearable sensors distributed around the body of a subject user. This has huge implications for the field of sports and human performance and opens a whole new field of research in the clinical setting. F.

“…This involved using a pH sensitive dye which changes colour depending on the pH of the sweat. This colour changewas detected by diffuse reflectance measurement using an emitterdetector LED technique developed in our laboratory [26]. During exercise, human sweat typically varies from pH 5-7 [15].…”

“…This is generally achieved by using a micropump. Mechanical micropumps have many limitations that include high operation voltage, high power consumption, complicated configuration and incompatibility with the wearable format [26]. Therefore, this work has focused on the development of a textile based sample collection and delivery method.…”

“…7. The model for the best-fit sigmoid curve fitted to the data was I = (a/(1 + eb(pH−z)))+ c where I is the detected light intensity, a is the peak height, b is the slope coefficient, z is the point of inflection and c accounts for a baseline offset [26]. The pKa for this sensor is estimated to be 6.5 which is slightly higher than the literature value of 6.2.…”

“…Not only is it important to replace fluids but also to replace electrolytes that are lost through sweating. As part of the Biotex project, an EU funded project [2], a fabric based system has been developed to analyse sweat during exercise [3,4]. A fabric channel is dyed with a pH sensitive indicator which has a colorimetric response.…”

-There is a need for wearable sensors to assess physiological signals and body kinematics during exercise. Such sensors need to be straightforward to use, and ideally the complete system integrated fully within a garment. This would allow wearers to monitor their progress as they undergo an exercise training programme without the need to attach external devices. This takes physiological monitoring into a more natural setting. By developing textile sensors the intelligence is integrated into a sports garment in an innocuous manner. A number of textile based sensors are presented here that have been integrated into garments for various sports applications.
