Electromechanical properties of thin strip piezoelectric vibrators at high frequency
A method was developed and used to determine the electromechanical properties of high frequency ~.20 MHz! piezoelectric strip vibrators. A nonlinear regression technique was employed to fit the impedance magnitude and phase as predicted by Mason’s model to measured values. Results from experimental measurements on 30 MHz array elements supported by an attenuative backing indicated degraded perf...
متن کاملLow-frequency vibration treatment of bone marrow stromal cells induces bone repair in vivo
Objective(s):To study the effect of low-frequency vibration on bone marrow stromal cell differentiation and potential bone repair in vivo. Materials and Methods:Forty New Zealand rabbits were randomly divided into five groups with eight rabbits in each group. For each group, bone defects were generated in the left humerus of four rabbits, and in the right humerus of the other four rabbits. To t...
متن کاملThin Impedance Vibrators - Theory and Applications
In this age of modern era, the use of internet must be maximized. Yeah, internet will help us very much not only for important thing but also for daily activities. Many people now, from any level can use internet. The sources of internet connection can also be enjoyed in many places. As one of the benefits is to get the on-line thin impedance vibrators theory and applications book, as the world...
متن کاملAnalytical Methods in the Theory of Thin Impedance Vibrators
The advantages and disadvantages of more extended approximated analytical methods of the integral equations solution for the current in thin perfectly conducting and impedance vibrators have been investigated in details in this paper. The solutions of the problem about the electromagnetic waves scattering by the thin vibrators with the distributed surface impedance, obtained with the help of th...
متن کاملFrequency Response of Sensors
For most force measurement applications, the strain gage based transducer can be relied upon to faithfully convert a mechanical input into a proportional electrical analog output signal. However, when the mechanical input is either applied or changes at a rapid rate, the sensor may distort the conversion and the user should be aware of the possible consequences of this distortion. This article ...
