Subnanowatt Microbubble Pressure Transducer

We present the first all-Parylene microbubble pressure transducer (μBPT). The μBPT utilizes an electrolytically generated microbubble (μB), trapped in a Parylene microchamber, for pressure sensing. Pressure-induced bubble size variation is detected by electrochemical impedance measurement. Real-time hydrostatic pressure measurement with excellent sensitivity (-10.7 Ω/psi, ±0.1 psi) up to 1.8 ps...

Complications associated with fractured file removal using an ultrasonic technique.

A technique utilizing modified Gates Glidden burs and ultrasonics has recently been advocated to remove fractured instruments from root canals. Varying extents of tooth structure are removed during this procedure, potentially leading to complications. This study evaluated the in vitro and in vivo complications associated with fractured file removal. Fractured instrument fragments were removed f...

Ultrasonic Attenuation Measurement Using Backsgattering Technique

Ultrasonic backscattering measurements by means of spatial averaging technique were carried out in steel to determine the ultrasonic attenuation coefficient. The attenuation coefficients were evaluated from the exponential decay of the backscattering signal. The results were compared with those obtained by evaluating the amplitude decay of the main pulse. Good agreement is observed provided the...

Modeling and investigating the effect of ultrasound waves pressure on the microbubble oscillation dynamics in microvessels containing an incompressible fluid (Research Article)

Understanding the dynamics of microbubble oscillation in an elastic microvessel is important for the safe and effective applications of ultrasound contrast agents in imaging and therapy. Numerical simulations based on 2D finite element model are performed to investigate the effect of acoustic parameters such as pressure and frequency on the dynamic interaction of the fluid-blood-vessel system. ...

Microbubble shape oscillations excited through ultrasonic parametric driving.

An air bubble driven by ultrasound can become shape-unstable through a parametric instability. We report time-resolved optical observations of shape oscillations (mode n=2 to 6) of micron-sized single air bubbles. The observed mode number n was found to be linearly related to the ambient radius of the bubble. Above the critical driving pressure threshold for shape oscillations, which is minimal...
