Steve Rothberg,Matthew S. Allen,Paolo Castellini,Dario Di Maio,Joris J.J. Dirckx,David J. Ewins,Ben J. Halkon,Pieter G.G. Muyshondt,Nicola Paone,Teresa J. Ryan,H. Steger,Enrico Primo Tomasini,Steve Vanlanduit,Joseph F. Vignola +13 more
TL;DR: This comprehensive review paper charts advances in the development and applications of laser Doppler vibrometry (LDV) since those first pioneering experiments, and considers the challenges that continue to be posed by laser speckle.
Journal ArticleDOI
Thermoelastic loss in microscale oscillators
TL;DR: In this article, a simple model of thermoelastic dissipation is proposed for general, free standing microelectromechanical (MEMS) and nanoelectromeechanical oscillators, which defines a flexural modal participation factor, the fraction of potential energy stored in flexure.
Journal ArticleDOI
Attachment loss of micromechanical and nanomechanical resonators in the limits of thick and thin support structures
TL;DR: In this paper, analytical expressions for the energy loss from vibrating mechanical resonators into their support structures for two limiting cases: supports that can be treated as plates, and supports that act as semi-infinite elastic media, with effectively infinite thickness.
Journal ArticleDOI
Effect of viscous loss on mechanical resonators designed for mass detection
Joseph F. Vignola,John A. Judge,Jacek Jarzynski,Maxim Zalalutdinov,Brian H. Houston,Jeffrey W. Baldwin +5 more
TL;DR: In this paper, a simple model for estimating viscous damping of fluid (gas or liquid) loaded mechanical resonators is presented, which applies to beams in flexural modes of vibration, and to thin beams and plates in longitudinal modes of vibrations.
Journal ArticleDOI
A loss mechanism study of a very high Q silicon micromechanical oscillator
Xiao Liu,Joseph F. Vignola,Harry J. Simpson,B. R. Lemon,Brian H. Houston,Douglas M. Photiadis +5 more
TL;DR: In this paper, the authors investigated the internal loss mechanisms of silicon micromechanical oscillators and concluded that near-surface lattice defects caused by reactive-ion etching and surface adsorbates are the main source of internal loss while surface ads absorbates are responsible for the time dependence.
