MEMS Gyroscopes’ Noise Simulation Algorithm
2019MEMS 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 ...

MEMS Gyroscopes as Physical Unclonable Functions
Proceedings of the 2016 ACM SIGSAC Conference on Computer and Communications Security, 2016A key requirement for most security solutions is to provide secure cryptographic key storage in a way that will easily scale in the age of the Internet of Things. In this paper, we focus on providing such a solution based on Physical Unclonable Functions (PUFs).

Parametric amplification/damping in MEMS gyroscopes
2011 IEEE 24th International Conference on Micro Electro Mechanical Systems, 2011The attainable resolution of inertial sensors is ultimately limited by the cumulated noise level generated in both the mechanical domain (mechano-thermal noise) and the frontend of the electrical readout circuit, provided that deterministic errors, such as quadrature errors in the case of gyroscopes, are kept under control.

Rotating and Gyroscopic MEMS Energy Scavenging
International Workshop on Wearable and Implantable Body Sensor Networks (BSN'06), 2006Extracting 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:

Mechanical-thermal noise in MEMS gyroscopes
IEEE Sensors Journal, 2005We derive expressions for the effect of mechanical thermal noise on a vibrational microelectromechanical system gyroscope, including the angle of random walk, the noise equivalent rotation rate, and the spectral density of the noise component of the rate measurement.

System for MEMS Gyroscope Testing
2016This paper presents fundamental information about an apparatus for tests on MEMS gyroscopes. Within the introductory section, the measurement system used to test MEMS gyroscopes at a Honeywell laboratory is characterized; the set-up comprises a Polytec MSA-500 analyzer, goniometers, and a controller.
