Force based displacement measurement in micromechanical devices

, 2001
We demonstrate how force detection methods based on atomic force microscopy can be used to measure displacement in micromechanical devices. We show the operation of a simple microfabricated accelerometer, the proof mass of which incorporates a tip which ...

Materials selection in micromechanical design: an application of the Ashby approach [PDF]

, 2003
The set of materials available to microsystems designers is rapidly expanding. Techniques now exist to introduce and integrate a large number of metals, alloys, ceramics, glasses, polymers, and elastomers into microsystems, motivating the need for a ...

CIRCUIT DESIGN PROPOSALS FOR IMPROVING THE METROLOGICAL CHARACTERISTICS OF A MICROMECHANICAL ACCELEROMETER WITH A CAPACITIVE DISPLACEMENT SENSOR

Измерение, мониторинг, управление, контроль
Background. Modern accelerometers based on microelectromechanical systems (MEMS) have a very low cost, are distinguished by their miniaturization and low energy consumption.
