A vacuum packaged surface micromachined resonant accelerometer
Ashwin A. Seshia,M. Palaniapan,T.A. Roessig,Roger T. Howe,R.W. Gooch,T.R. Schimert,S. Montague +6 more
TL;DR: In this paper, the authors describe the operation of a vacuum packaged resonant accelerometer subjected to static and dynamic acceleration testing and show that it exhibits a noise floor of 40 /spl mu/g/g//spl radic/(Hz) for an input acceleration frequency of 300 Hz.
Journal ArticleDOI
A vibrating beam MEMS accelerometer for gravity and seismic measurements
Arif Mustafazade,Milind Pandit,Chun Zhao,Guillermo Sobreviela,Zhijun Du,Philipp Steinmann,Xudong Zou,Xudong Zou,Roger T. Howe,Ashwin A. Seshia +9 more
TL;DR: The results demonstrate that vibrating beam MEMS accelerometers can be employed for measurements requiring high levels of stability and resolution with wider implications for precision measurement employing other resonant-output MEMS devices such as gyroscopes and magnetometers.
Journal ArticleDOI
A review on coupled MEMS resonators for sensing applications utilizing mode localization
Chun Zhao,Chun Zhao,Mohammad H. Montaseri,Graham S. Wood,Suan Hui Pu,Ashwin A. Seshia,Michael Kraft +6 more
TL;DR: In this article, the authors review a recent technology development based on coupled MEMS resonators that has the potential of fundamentally transforming MEMS Resonant sensors, including the mode localization effect.
Proceedings ArticleDOI
Dynamics and control of micromachined gyroscopes
TL;DR: In this paper, the authors summarize principles of operation of micromachined gyroscopes, analyze dynamics of ideal and non-ideal systems, and propose an approach for formulation and solving problems of control.
