Rotating and Gyroscopic MEMS Energy Scavenging

International Workshop on Wearable and Implantable Body Sensor Networks (BSN'06), 2006
Extracting energy from motion and vibration is an attractive route to powering wireless sensors, and MEMS (microelectromechanical systems) technology is well suited to miniaturizing such generators. Most reported MEMS motion-driven scavengers use linear displacement, and have very restricted output power. Here two alternatives are proposed and analyzed:

Active disturbance rejection control for MEMS gyroscopes

2008 American Control Conference, 2008
A new control method is presented to drive the drive axis of a MEMS gyroscope to resonance and regulate the output amplitude of the axis to a fixed level. It is based on a unique active disturbance rejection control (ADRC) strategy, which actively estimates and compensates for internal dynamic changes of the plant and external disturbances in real time.

A Parametrically Amplified MEMS Gyroscope

Additional Conferences (Device Packaging, HiTEC, HiTEN, and CICMT), 2010
The applicability of parametric amplification of either the primary and secondary vibration modes of a MEMS gyroscope, shown in Fig.1 is investigated experimentally in this paper. All control schemes have been implemented digitally onto a SHARC DSP development board.

MEMS Gyroscopes’ Noise Simulation Algorithm

2019
MEMS gyroscopes are advantageous devices that promote a wide range of applications, however, they suffer from various stochastic errors some of which accumulate over time (angle random walk, bias random walk). To be able to use such devices, one should apply mathematical models of stochastic processes and hardware-software tools for investigation into ...

Reliability of vacuum packaged MEMS gyroscopes

Microelectronics Reliability, 2005
The greatest challenge for the successful commercialization of MEMS (micro-electro-mechanical system) technology is proving its reliability. Of concern in particular are the reliability and long-term stability of wafer level vacuum packaged MEMS gyroscope sensors subjected to cyclic mechanical stresses at high frequencies. In this study, we carried out

On the control of vibratory MEMS gyroscopes

Smart Structures and Systems, 2010
This paper addresses the control issue of vibratory MEMS-based gyroscopes. This study considers a gyroscope that can be modeled by an inner mass attached to an outer mass by four springs and four dampers. The outer mass itself is attached to the rotating frame by an equal number of springs and dampers.
