In this paper, a parameterized reduced model of a vibratory microelectromechanical systems (MEMS) gyroscope is established using a parametric model order reduction algorithm. In the reduction process, not only the input angular velocity, material density, Young's modulus, and Rayleigh damping coefficient but also the coefficient of thermal expansion and the change in temperature were all preserved...
A microfabricated breath sensor based on multi-walled carbon nanotubes (MWCNTs) has been designed, developed and tested. This sensor has a simple capacitor structure, including a pair of metal electrodes fabricated by micromachining, which are then coated by a layer of carbon nanotubes. This structure takes advantage of the unique electrical property of MWCNTs in the small gap space as a function...
We have demonstrated here the successful operation of an ionization gas sensor with gap spacing 2~10 mum and using CNTs (carbon nanotubes) as the electrode material. By set up an appropriate threshold current, the application of less than 20 V DC bias could generate electric field enough to effectively ionize various gases in atmospheric pressure. Working by the fingerprinting ionization characteristics...
