We report a new easier method for the quantitative analysis of sodium in human sweat. To the best of our knowledge this is the first time this has been done successfully in a real-time manner. We consolidate sweat stimulation, collection and analysis functions into a single method. This temporal data opens up new possibilities in the study of human(More)
The cost of monitoring greenhouse gas emissions from landfill sites is of major concern for regulatory authorities. The current monitoring procedure is recognised as labour intensive, requiring agency inspectors to physically travel to perimeter borehole wells in rough terrain and manually measure gas concentration levels with expensive hand-held(More)
This paper details the development of a textile based fluid handling system with integrated wireless biochemical sensors. Such research represents a new advancement in the area of wearable technologies. The system contains pH, sodium and conductivity sensors. It has been demonstrated during on-body trials that the pH sensor has close agreement with(More)
A feasibility study on a new technique capable of monitoring localized sweat rate is explored in this paper. Wearable devices commonly used in clinical practice for sweat sampling (i.e., Macroducts) were positioned on the body of an athlete whose sweat rate was then monitored during cycling sessions. The position at which the sweat fills the Macroduct was(More)
A wireless sensor network has been developed for the application of landfill gas monitoring, specifically sensing methane, carbon dioxide and extraction pressure. This collaborative work with the Irish Environmental Protection Agency has been motivated by the need to reduce greenhouse gas emissions as well as aiming to improve landfill gas management and(More)
In this work we present a flexible and wearable micro-fluidic device for the continuous monitoring of pH changes in sweat during exercise. The sensing capability is based on ionogels, ionic liquid polymer gels, containing pH sensitive dyes capable of reporting pH activity in the range from pH 3 to pH 8. Optical detection is performed using a mobile phone(More)
In this paper a wearable electronic-free micro-fluidic device for the continuous monitoring of pH in sweat during exercise is described. The sensing capability is based on ionogels, ionic liquid hydrogels, containing pH sensitive dyes capable of reporting pH activity in the range from 3 to 10. Previously, we reported a flexible micro-fluidic barcode capable(More)
The development of wearable sensing technologies is a great challenge which is being addressed by the Proetex FP6 project (www.proetex.org). Its main aim is the development of wearable sensors to improve the safety and efficiency of emergency personnel. This will be achieved by continuous, real-time monitoring of vital signs, posture, activity, and external(More)
—In this paper, we present a novel microfluidic optical sensing system by combining a low-power conductive polymer-based microfluidic pump and a microfluidic chip integrated with an optical sensor. A self priming microfluidic pump is developed using a polypyrrole. A microfluidic chip-optical detector module that contained an optical cuvette with LED and(More)
