TL;DR: In this paper, a highly sensitive hydrogen-gas sensor fabricated using MEMS technology is presented, which consists of glass substrates, silicon substrate and an AT-cut quartz crystal resonator, which is embedded in the microchannel constructed on the substrates.

TL;DR: In this article, a probe adaptively adjusted thin-wall part on-machine ultrasonic thickness measuring method was proposed, in which a ball-shaft mechanism was adopted to act as an adaptive adjustment mechanism, and a coupling agent injection mechanism was utilized to provide stable coupling liquid level for ultrasonic measurement.

TL;DR: In this paper, a surface residual stress ultrasonic detection method capable of achieving direct coupling wave generation is proposed, where a wave generation mode of coupling agent direct coupling is adopted, ultrasonic waves pass through a single coupling agent medium and directly emit into a measured material, and an adopted direct coupling probe is in a one-emitting double-receiving stress measurement mode.

TL;DR: In this article, an ice immobilization machining method for a metal honeycomb workpiece was proposed, which achieved the purpose of clamping of the metal honeycombs difficult to machine, the freezing temperature of the pure water or the cutting liquid and the temperature maintaining degree are effectively controlled, the machining immobilizing effect can be better, and the cutting precision is improved.

TL;DR: In this article, the authors presented a wireless quartz crystal microbalance (QCM) biosensor fabricated using MEMS technology, which contains a 125 MHz AT-cut quartz resonator embedded in the microchannel.
