Athletes’ sweat test road to glory

The 2012 Olympics

Dehydration can undermine

Hydration levels

Track athletes in Ireland preparing for the 2012 Olympics have been testing a device designed to improve performance by optimising their hydration levels during training. Dehydration can undermine both mental and physical performance, including causing tiredness and cramping. Analysis of sweat samples taken after training is unreliable because the key compounds oxidise when in contact with air. “It does not give a real measure of what is happening during exercise,” says Fernando Benito Lopez at the Clarity Centre for Sensor Web Technologies at Dublin City University.To tackle the problem, Benito Lopez and colleagues have developed a device that assesses hydration levels while athletes are training. It is based on an absorbent pad strapped to the athlete’s body, which draws sweat through a narrow channel containing pH sensors.

Ionogel Channels

Colour sensors

Benito Lopez is investigating the use of two different types of sensor. One uses a patch of pH-sensitive textile. The other uses an ionic dye which changes colour in the presence of sodium ions.
An LED is used to illuminate the sensor while a second light-sensitive LED detects the colour changes by measuring the intensity of light reflected off it. The resulting readings, sent wirelessly to the trackside, tell the coach the sodium content of the athlete’s sweat and therefore their hydration level. Based on this information, the coach can fine-tine the athlete’s training programme. Initial tests show the pad can continuously monitor pH changes for up to 3 hours. This could be potentially very useful, says Charlie Pedlar, a research physiologist at the Endurance Performance and Coaching Centre at St Mary’s University College in Twickenham, UK, who worked with the British Olympic team in Beijing, China, in 2008. “We measure body weight before and after training to measure water loss through sweat and breathing,” he says. But he says this does not give enough information to optimise athletes’ water intake and avoid dehydration.Benito Lopez and colleagues are investigating whether it is possible to apply the same approach to lactate, which is also present in sweat.

Calibration our Religion

MicroTas 2010

Dermot Diamond

Center for Sensor Web technologies

This statement was heard yesterday (october 4th 2010) in microTas2010 (Miniaturized Systems for Chemistry and Life Sciences  3 – 7 October 2010)

Clarity

This all was said by Dermot Diamond from Dublin City University of Ireland. He works in the CLARITY Center for Sensor Web technologies.

The microTAS principle (evolution)

From evolution to revolution

Water quality monitoring: stimulus-responsive materials the key to the analytical platforms of the future?”. I myself was listening and looking to this presentation from a medical point of view. We use sensors more and more in Medicine, but there are problems.

Sensor Hierarchy (D.Diamond)

The sensor surface will change with time (sometimes within a day). Calibration is a huge problem. There is a need for new techniques to scale-up.

Scale-up (D.Diamond)

Photoswitchable materials can give an answer:

Wanda

Even it’s possible to make polymer pumps this way. What to move…like chemotaxis. Even a robotfish called Wanda (Wireless Aquatic Navigator for Detection and Analysis) with a built-in camera is produced.

Willem Alexander opent MicroTAS2010

4 oktober 2010 om 20:06 uur door Jan Taco te Gussinklo

1000 Wetenschappers

Deze week zijn 1000 wetenschappers uit 30 landen in Groningen bijeen om in 600 presentaties innovaties op het terrein van Microfluids en Lab-on-a-Chip uit te wisselen onder de naam MicroTAS2010. De Kroonprins verricht de openingshandeling in het Martiniplaza waarna de eerste voordracht op maandag 4 oktober van start gaat.

Deze voordracht handelt over de revolutionaire ontwikkeling bij het monitoren van de waterkwaliteit, een onderwerp dat alle aandacht krijgt van de koninklijke bezoeker

Prins Willem Alexander in gesprek met Prof.Albert van den Berg (MESA+)


Na de pauze geeft Prof.Albert van den Berg uit Twente (MESA+) een fraai overzicht van de kansen van de nieuwe techniek in de Gezondheidszorg.
