Long-Term Aging Study of a Silicon Nitride Nanomechanical Resonator
Michel Stephan, Alexandre Bouchard, Timothy Hodges +4
Short-term changes in the resonance frequency of silicon nitride (SiN) nanomechanical resonators can be measured very precisely due to low thermomechanical fluctuations resulting f…
Vibration Sensitivity of one-port and two-port MEMS microphones
Francis Doyon-D'Amour, Carly Stalder, Timothy Hodges +5
Micro-electro-mechanical system (MEMS) microphones (mics) with two acoustic ports are currently receiving considerable interest, with the promise of achieving higher directional se…
Localized Thermal Gradients On-Chip by Radiative Cooling of Silicon Nitride Nanomechanical Resonators
Alexandre Bouchard, Timothy Hodges, Michel Stephan +4
Small scale renewable energy harvesting is an attractive solution to the growing need for power in remote technological applications. For this purpose, localized thermal gradients…
Comparison of measurement systems for assessing number- and mass-based particle filtration efficiency
Timothy A. Sipkens, Joel C. Corbin, Triantafillos Koukoulas +8
The particle filtration efficiency (PFE) of a respirator or face mask is one of its key properties. While the physics of particle filtration results in the PFE being size-dependent…
Systematic experimental comparison of particle filtration efficiency test methods for commercial respirators and face masks
Joel C. Corbin, Greg J. Smallwood, Ian Leroux +7
Respirators, medical masks, and barrier face coverings all filter airborne particles using similar physical principles. However, they are tested for certification using a variety o…
