Determining the various parameters of the mechanical properties of skin has an established role in scientific bioengineering studies. The new aspect of the measurement - based on Resonance Running Time of the Reviscometer® RV 600 - in addition to finding elastic and viscoelastic features is to determine the direction of the collagen and elastine fibres. Therefore it is an ideal addition to the very well established suction measurement method of the Cutometer®. The special measurement method of the Reviscometer® RV 600 allows investigation of new interesting fields as orientation of incision during cutaneous surgery, relation between body mass index and elasticity, photoageing and many more.
Interesting Aspects of Skin Elasticity
The Measuring Principle
The measuring principle is based on resonance running time. The probe head contains two sensors which are placed on the skin. One is emitting acoustical shockwaves, the other serves as receiver. Shockwaves propagate differently through the skin according to the state of the elastic fibres and the moisture content of the skin. The time As the time depends to a high amount on the fact whether the measurement is executed with the direction of the fibres or against it, and the measurement can be performed in different directions on the same skin site, the direction of the fibres is measured. the wave needs to travel from emitter to receiver is the measured parameter.
As the time depends to a high amount on the fact whether the measurement is executed with the direction of the fibres or against it, and the measurement can be performed in different directions on the same skin site, the direction of the fibres is measured.
A positioning top with marks for the direction in 0- 180ˇă, 45-225ˇă, 90-270ˇă, and 135-315ˇă-axis, fixed with a double sided adhesive ring, enables the user to easily measure in all directions on one skin site.
The Probe
The modern, high quality electronics of the probe allow a very quick, easy and precise measurement. Its low weight assists in ease of handling. All calibration data are inside the probe. Thus the probe is completely self contained and can be connected to different device types. It is also a significant advantage for quick and easy servicing of the probe. Together with the Cutometer® MPA 580, which measures the visco-elastic properties by suction, the Reviscometer® RVM 600 can form an ˇ°elasticity measurement centreˇ± to examine this parameter from different angles.
Check Calibration
The new technology of the Reviscometer® RV 600 does not require frequent, complicated and time consuming recalibration. The accuracy of the device can easily be checked at any time on a special silicone material.
