Green pressure sensors tap quartz MEMS
News & Analysis  
6/29/2009   Post a comment
Epson Toyocom unveiled a green sensor technology that eliminates dangerous oil and gases from pressure sensors, instead using a quartz microelectromechanical system (QMEMS) tuning fork as the sensing element.
Electronic nose sniffs out cancer
News & Analysis  
6/25/2009   Post a comment
Anecdotal evidence that dogs can detect cancer by smell inspired researchers to combine clever chemistry with optical detectors to craft an electronic nose that they claim can not only screen for any kind of cancer, but also determine whether it is aggressive.
