Enhanced bandwidth multi1ayer transducers for imaging applications

open access: yesArchives of Acoustics, 2014
The operating frequency of the presently used PZT or PZT composite ultrasound imaging transducers is determined by the half wavelength resonance or fundamental thickness mode of vibration. This resonance frequency together with the two quarter wavelength

High Temperature Dynamic Pressure Measurements Using Silicon Carbide Pressure Sensors [PDF]

open access: yes
Un-cooled, MEMS-based silicon carbide (SiC) static pressure sensors were used for the first time to measure pressure perturbations at temperatures as high as 600 C during laboratory characterization, and subsequently evaluated in a combustor rig operated
