Effect of surface stress on microcantilever resonance frequency during water adsorption: influence of microcantilever dimensions.

This paper reports the effect of dimensions of microcantilever (MC) on its resonance frequency and bending upon adsorption of water molecules. Study is conducted on three MCs having the dimensions of 450 × 40 × 2.5 μm(3) (MC1), 225 × 30 × 3 μm(3) (MC2) and 125 × 35 × 4.

PSoC-based embedded design and quartz tuning fork for low-temperature measurement system design.

This article describes a commercial quartz tuning fork (QTF), 8 mm in height by 3 mm in diameter, holding a two-terminal electronic component with a nominal frequency of 32.768 kHz and 12.5 pF typical load capacitance packed in a vacuum-sealed metal container, which has been used as a sensor for low-temperature measurement with good sensitivity, repeatability, and reliability.
