Journal ArticleDOI
Robust micro-rate sensor actuated by parametric resonance
TL;DR: Yazdi et al. as mentioned in this paper proposed a micro-gyroscope that is less sensitive to parameter variations due to its inherent dynamical properties and demonstrated experimentally that using a parametric resonance based actuator, the drive-mode signal has a rich dynamic behavior with a large response in a large bandwidth (1.kHz).
Journal ArticleDOI
Graphitizing Non-graphitizable Carbons by Stress-induced Routes.
Maziar Ghazinejad,Maziar Ghazinejad,Sunshine Holmberg,Oscar Pilloni,Laura Oropeza-Ramos,Marc J. Madou +5 more
TL;DR: It is demonstrated how electro-mechanical aspects of the synthesis process influence molecular alignment in a polymer precursor to enhance its graphitization.
Journal ArticleDOI
New perspectives for direct PDMS microfabrication using a CD-DVD laser

TL;DR: Thanks to a precise and automated control of laser conditions, laser-induced incandescence is originated at the material surface and produces high-resolution micropatterns that present properties normally induced with lasers of much greater energies in PDMS: formation of in situ nanodomains, local fluorescence and waveguide patterns.
Proceedings ArticleDOI
Inherently robust micro gyroscope actuated by parametric resonance
TL;DR: In this paper, the authors report complete rate table characterization including off-axis isolation, drift, hysteresis and noise of the micro gyroscope with an additional amplification stage.
Proceedings ArticleDOI
Parametric resonance amplification in a MEMGyroscope
TL;DR: In this paper, a feasibility analysis of using parametric amplification in order to improve the performance of a micromachined rate gyroscope is presented, where the actuation is based on variable force actuators that depend on the force-time variation relation, thus the nonlinear Mathieu equation governs the driving motion.
