Gas leak detector

11.12.2002


Micro-sensors, developed by the CEIT Technology Centre with the help of Gas de Euskadi, operate by detecting gas leaks and reducing the risks of poisoning through the inhalation of carbon monoxide gas.



Through research involving help from Gas de Euskadi, CEIT has developed a system based on micro-sensors that can detect domestic gas leaks. The increasing use of natural gas in homes, the future regulations for carbon monoxide detection in domestic situations and the growing demand for gas detectors have been the main reasons why the young researcher from CEIT, Gemma García Mandayo, has directed her research to techniques for the creation of tin oxide micro-sensors.

In order to both prevent gas leaks and avoid carbon monoxide formation, the correct installation and the suitable maintenance of gas appliances are essential, and equally so their compliance with the relevant standards and regulations. Nevertheless, with the aim of increasing safety, the systems that have been developed significantly reduce the possibility and risk of both explosions due to leaks of methane (main component of natural gas) and, likewise, of poisoning due to the presence of carbon monoxide, a colourless, odourless gas.


Given its characteristics, it is impossible to detect carbon monoxide without the presence of a sensor. Correct ventilation of those spaces where combustion is carried out is an important preventative measure, despite the fact that there is always a risk of accumulation of this gas, given its high density and its lack of colour or smell. The Journal of the American Medical Association has pointed out that carbon monoxide is the principal cause of accidental death in the United States of America.

The researchers at CEIT have started on the design of the gas micro-sensor. This involves the incorporation of a heater in order to apply the tin oxide film at a temperature of 300° C, the temperature at which the carbon monoxide is detected.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
