Here we investigate the feasibility of textile based piezoresistive sensors to accurately measure increases in spinal extension, on-body for clinical application in the Modified Modified Schober's test. The proposed sensor combines the accuracy of standard metallic strain sensors with the comfort and usability of textiles, offering innumerable wearable applications. Calibration testing of the textile...
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...
Textile based devices for biochemical analysis of body fluids represent a new development in the area of wearable sensors. This paper outlines the development of a fluid handling system and wireless sensors for the real-time analysis of sweat pH and sodium levels during exercise. Liquid is drawn into the system using a moisture wicking material and passive pump. The sensor then displays pH induced...
Bio-sensing textiles to perform on-body bio-chemical analysis are a novel concept in the field of wearable technologies. This work is part of BioTex, an EU funded project aiming to develop textile -based sensors for monitoring biological fluids. A fabric-based fluid handling system has been developed which has promising advantages including potential for sophisticated control of functions like sample...
BioTex is an EU funded project aiming to develop textile-based sensors for monitoring biological fluids. In the context of the project, there is a need to develop an effective sample delivery strategy for the wearable biomedical devices. A compact, electroactive switchable membrane would be useful as a valve to control the sample delivery within such devices. A method that employed inherently conducting...
A distributed Monte Carlo simulation which models the propagation of light through tissue has been developed. It allows for improved calibration of medical imaging devices for investigating tissue oxygenation in the white matter of the cerebral cortex. The application can distribute the simulation over an unbounded number of processors in parallel. We have found that this application is highly parallelisable...
Near-infrared spectroscopy is a non-invasive optical method used to detect functional activation of the cerebral cortex. Cognitive, visual, auditory and motor tasks are among the functions that have been investigated by this technique in the context of optical brain computer interfacing. In order to determine whether the optical response is due to a stimulus, it is essential to identify and reduce...
