Temperature Compensated SAW Devices Using Bonded LiTaO3/Sapphire

A Novel Wireless and Temperature-Compensated SAW Vibration Sensor

A novel wireless and passive surface acoustic wave (SAW) based temperature-compensated vibration sensor utilizing a flexible Y-cut quartz cantilever beam with a relatively substantial proof mass and two one-port resonators is developed. One resonator acts as the sensing device adjacent to the clamped end for maximum strain sensitivity, and the other one is used as the reference located on clamp...

Temperature-compensated chemical reactions.

Circadian rhythms are daily oscillations in behaviors that persist in constant light/dark conditions with periods close to 24 h. A striking feature of these rhythms is that their periods remain fairly constant over a wide range of physiological temperatures, a feature called temperature compensation. Although circadian rhythms have been associated with periodic oscillations in mRNA and protein ...

Optimization of SiO2 Films and Application of Fluorine Doped SiO2 Films for Temperature Compensated Surface Acoustic Wave Devices SAW SiO2 SiOF

Recently, temperature compensation of surface and bulk acoustic wave (SAW/BAW) technologies has become a topic of interest due to strong demand on wideband filters with excellent temperature stability. Two types of techniques are studied extensively. One is the wafer bonding of a piezoelectric substrate with a support substrate, which have large Young's modulus and small thermal expansion coeff...
