Photo-Induced Force Microscopy by Using Quartz Tuning-Fork Sensor [PDF]

Sensors, 2019
We present the photo-induced force microscopy (PiFM) studies of various nano-materials by implementing a quartz tuning fork (QTF), a self-sensing sensor that does not require complex optics to detect the motion of a force probe and thus helps to ...

Applications of the quartz tuning fork in classical and superfluid hydrodynamics

EPJ Web of Conferences, 2012
We present a short review of the multitude of applications of the commercially produced quartz tuning fork in cryogenic fluid dynamics, using cold gaseous, normal liquid and superfluid 4He as working fluids with extraordinary, but well-known and tunable ...

Driveless Gyroscope Response of a Quartz Piezoelectric Vibratory Tuning Fork [PDF]

AIP Conference Proceedings, 2015
In this paper, we report on the observation of a gyroscope response in the absence of drive oscillator circuitry in a single ended quartz piezoelectric tuning fork. The tuning fork gyroscope was fabricated by conventional photolithography and wet etching

Quartz Enhanced Photoacoustic Spectroscopy Based Gas Sensor with a Custom Quartz Tuning Fork

Proceedings, 2018
We have fabricated a custom quartz tuning fork (QTF) with a reduced fundamental frequency, a larger gap between the prongs and the best quality factor in air at atmospheric conditions ever reported.

Clamp-type quartz tuning fork enhanced photoacoustic spectroscopy

Optics Letters, 2022
In this Letter, clamp-type quartz tuning fork enhanced photoacoustic spectroscopy (Clamp-type QEPAS) is proposed and realized through the design, realization, and testing of clamp-type quartz tuning forks (QTFs) for photoacoustic gas sensing.
