INTERFEROMETRIC MEASUREMENT OF ULTRASONIC VELOCITIES WITH LINE-FOCUSING P(VDF-TrFE) TRANSDUCER: V(t) CURVES
Acoustic microscopy [1] is used to measure the V(Z) curves and thereby determine the ultrasonic velocities on the surfaces of solid materials. The acoustic transducer, pointor line-focusing, is defocused below the sample surface through the coupling water. The focal depth Z is changed to extract the interference between the specular reflection signal and the leaky surface wave signal(s). Their ...
متن کاملDesign and Fabrication of a Longitudinal-Torsional Ultrasonic Transducer
A hybrid longitudinal-torsional ultrasonic transducer is designed and fabricated in this research. The design of the transducer was performed using the FE method with ABAQUS software, with the aim of combining the longitudinal and torsional vibration modes. The transducer horn is then fabricated using a 4-axis milling machine. The PZT stacks are employed in order to excite the transducer. The t...

متن کاملImproved Ultrasonic Piezoceramic Sandwich Transducer
This paper presents an improved ultrasonic piezoceramic sandwich transducer, utilised for ultrasonic field in narrow lift stations, wet well, flumes and filter beds. The piezoceramic sandwich transducer powered by a signal generator and it is suitable to generate ultrasound with two piezoceramics and the exponential horn at 35 kHz resonance frequency. From the experiments it can be proved that ...
متن کاملTwo-Dimensional Capacitive Micromachined Ultrasonic Transducer (CMUT) Arrays for a Miniature Integrated Volumetric Ultrasonic Imaging System
We have designed, fabricated, and characterized two-dimensional 16x16-element capacitive micromachined ultrasonic transducer (CMUT) arrays. The CMUT array elements have a 250-μm pitch, and when tested in immersion, have a 5-MHz center frequency and 99% fractional bandwidth. The fabrication process is based on standard silicon micromachining techniques and therefore has the advantages of high yi...
