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.

Automatic assembly of quartz tuning fork and microcantilever

2012 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2012
Conventional atomic force microscopes (AFMs) detect microcantilever deflection using an optical lever system. However, the complex mechanism of the optical lever system and the alignment of the laser spot on the microcantilever prevent such AFM systems from scanning large samples. AFM systems using a quartz tuning fork (QTF) as a force sensor have been

Electrostatic force microscopy using a quartz tuning fork

Applied Physics Letters, 2002
We demonstrate an electrostatic force microscopy based on a quartz tuning fork with 50 nm spatial resolution and 1 pN force sensitivity. We use a tuning fork with a spring constant of 1300 N/m and a Q factor of 3000. A sharpened nickel tip is attached to a prong of the tuning fork as well as electrically connected to the electrode of the prong.
