Quartz Tuning Fork Viscometers for Helium Liquids

Journal of Low Temperature Physics, 2004
Mechanical resonators, in the form of vibrating wires or torsional oscillators, have long been employed as sensors in liquid 3He and 3He–4He mixtures. The damping of resonators is due to the viscosity of the surrounding liquid which is a strong, well-known function of temperature for bulk Fermi liquids.

Effective stiffness of qPlus sensor and quartz tuning fork

Ultramicroscopy, 2014
Quartz tuning forks (QTFs) have been extensively employed in scanning probe microscopy. For quantitative measurement of the interaction in nanoscale using QTF as a force sensor, we first measured the effective stiffness of qPlus sensors as well as QTFs and then compared the results with the cantilever beam theory that has been widely used to estimate ...

Miniaturized Angular Rate Sensor with Laminated Quartz Tuning Fork

Japanese Journal of Applied Physics, 2006
We have developed a miniaturized angular rate sensor (5.0×3.2×1.3 mm3) with a laminated quartz tuning fork (3.7×0.97×0.24 mm3). An advanced reliable assembly process technology was applied to the packaging of LSI and the sensor element of the small thin sensor. Therefore, the sensor had high quality and superior mass productivity.
