In quest of improved nanomechanical sensitivity at larger damping and applications in ambient conditions
DownloadFall 2019
In the current state-of-the-art, a wide variety of devices, from computer clocks to smartphone accelerometers and from pressure gauges to atomic force microscope sensors, rely on mechanical resonators, either in microscale or nanoscale. Nanoscale mechanical resonators have even more potential...

Nanophotonic detection of nanomechanical structures for use toward mass sensing applications
DownloadSpring 2014
Nanomechanical beam resonators show much promise for use in integrated on-chip mass sensing systems. This follows from their own very small masses and also their ability to store the mechanical energy of their oscillations to produce strong measurable mechanical response signals. To achieve...
