The Performance Effects of Squeeze Film Stiffness on Non-resonate Interferometric Inertial Sensors
This paper studies the nonlinear effects of squeeze film stiffening on the performance of a high resolution MEMS nonresonant inertial sensor. It is shown that these effects introduce a surprising dynamic response that extends the operational frequency range of the devices by retarding the resonate response. In addition, this performance advantage will occur without the traditional gain trade-of...
متن کاملSqueeze-film damping of flexible microcantilevers
An improved theoretical approach is proposed to predict the dynamic behavior of long, slender and flexible microcantilevers affected by squeeze-film damping at low ambient pressures. Our approach extends recent continuum gas damping models (Veijola 2004 J. Micromech. Microeng. 14 1109–18, Gallis and Torczynski 2004 J. Microelectromech. Syst. 13 653–9), which were originally derived for a rigid ...
متن کاملPartial squeeze film levitation modulates fingertip friction.
When touched, a glass plate excited with ultrasonic transverse waves feels notably more slippery than it does at rest. To study this phenomenon, we use frustrated total internal reflection to image the asperities of the skin that are in intimate contact with a glass plate. We observed that the load at the interface is shared between the elastic compression of the asperities of the skin and a sq...
متن کاملGraphene Sensors
Polycrystalline graphene sensors are presented by Richard I. Masel and co-workers on page 53. The image shows polycrystalline graphene ribbon chemiresistors with gold contacts visualizing linear defects or wrinkles in the graphene. Floating or attached toluene molecules act as electron donors. Such defective graphene devices exhibit a higher chemical sensitivity than pristine graphene or carbon...
متن کاملMagnetic fluid based squeeze film between porous elliptical plates
Archibald [1] analyzed the performance of a squeeze film between various geometrical configurations. Later on Wu [2, 3] investigated a squeeze film behavior for mainly, two types of geometries namely, annular and rectangular. Prakash and Viz [4] developed some aspects of the analysis incorporated in Wu [2, 3] and obtained the load carrying capacity ultimately leading to time height relation for...
