A Nanoelectronic Sensor Which Can Save Lives

Roland Piquepaille writes "Researchers at Nanomix, a 20-person Californian company, have developed a nanoelectronic sensor which combines carbon nanotubes, carbon dioxide-detecting polymers and silicon to become a human breathing monitor. The device can determine carbon dioxide concentrations in exhaled air, according to "Monitoring Life, One Breath At A Time," a news release from the National Science Foundation. It could be used as early as 2005 to monitor patientsí breathing during surgery. Even more importantly, it will be used in the field for emergency care by helping to verify proper breathing tube placement or to provide feedback about adequacy of ventilation. This overview gives you more details and references. It also include an illustration of the carbon nanotube network device."
