Abstract
There is provided a system and method for the measurements of viscoelastic properties of a soft sample in which the system incorporates a sample holder that has a membrane with a flexural rigidity that is less than the flexural rigidity of the main body and allowing vibration of the membrane-sample vibration unit in response to a vibration excitation to create resonance vibration modes that are detected to derive the viscoelastic properties.
Claims20
A sample holder for measuring viscoelastic parameters of a soft sample, the holder comprising:
- a main body comprised of material having a flexural rigidity, the main body having a peripheral wall and a bottom to define therewith a closed sample-containing cavity;
- and
- an impermeable membrane having a flexural rigidity lower than the main body flexural rigidity, said membrane extending at least along a portion of the bottom and having an inner face exposed in the sample-containing cavity, such as to retain said soft sample in said holder, and wherein the soft sample is in contact with the membrane to form a vibration unit that is configured to allow vibrations when in the vibrations measurement mode.
