Rajaraman, V. (author), Sabageh, I. (author), French, P. (author), Pansraud, G. (author), Cretu, E. (author)This work reports the design, modelling, fabrication and preliminary functionality testing of a dual-mass MEMS vibratory gyroscope for application in medical instrumentation, among others. The two-framed gyro has drive and sense mode resonance frequencies of 2500Hz and 2830Hz, with its bandwidth tunable between 40-330Hz. Adopted design and...journal article 2011

Rajaraman, V. (author), Hau, B.S. (author), Rocha, L.A. (author), French, P.J. (author), Makinwa, K.A.A. (author)This work reports on the design and modeling of a new flexible contact-mode 1-DOF piezoresistive contact force and impacttime detector used for acceleration sensing in the time domain. The key advantages of the contact-mode detection mechanism are the use of simple readout circuitry, compactness, good linearity, scalability, and the potential to...journal article 2010
