Integrated structure for a resonant micro-gyroscope and accelerometer

A Simple and Fast Method for Field Calibration of Triaxial Gyroscope by using Accelerometer

Pull-In Instability and Vibrations of a Beam Micro-Gyroscope

Gyroscopes are used as rotation rate sensors. Conventional gyroscopes are heavy and bulky, which creates important problems regarding their usage in different applications. Micro-gyroscopes have solved these problems due to their small size. The beam micro-gyroscope is one of the popular types of inertial sensors. Their small dimensions and low energy consumption are key reasons for their popul...

A Micro-Machined Gyroscope for Rotating Aircraft

In this paper we present recent work on the design, fabrication by silicon micromachining, and packaging of a new gyroscope for stabilizing the autopilot of rotating aircraft. It operates based on oscillation of the silicon pendulum between two torsion girders for detecting the Coriolis force. The oscillation of the pendulum is initiated by the rolling and deflecting motion of the rotating carr...

Gesture-based User Authentication for Mobile Devicesusing Accelerometer and Gyroscope

In this paper a user authentication mechanism for handheld mobile devices using hand gestures is presented. To authenticate a prior chosen hand gesture needs to be repeated. The mobile device uses a 3D-accelerometer and a 3D-gyroscope to measure the resulting device movement. With a user study it was shown, that the presented approach is feasible and has advantages with regard to usability over...

A New Z-axis Resonant Micro-Accelerometer Based on Electrostatic Stiffness

Presented in the paper is the design, the simulation, the fabrication and the experiment of a new z-axis resonant accelerometer based on the electrostatic stiffness. The new z-axis resonant micro-accelerometer, which consists of a torsional accelerometer and two plane resonators, decouples the sensing movement of the accelerometer from the oscillation of the plane resonators by electrostatic st...
