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.
Claims26
A sample holder for measuring viscoelastic parameters of a soft sample comprising:
- a main body comprised of material having a flexural rigidity, and
- at least one section comprising a membrane having a lower flexural rigidity than said material of said main body, said membrane structurally connected to the main body such as to retain said soft sample in said holder and wherein the soft sample is in contact with the membrane when in vibrations measurements acquisition mode to form a vibration unit that is configured to allow vibrations and detection of said vibrations.
The sample holder as claimed in 4 wherein the soft sample has a thickness when in the sample holder and the section comprising the membrane has a thickness of from about 1/1000 to 1 times the thickness of the soft sample.

A process for manufacturing a product comprising:
- providing a manufacturing system configured to transform an input material into the product, wherein the transformation comprises one or more stages at which one or more viscoelastic properties of the material are required, and
- measuring the viscoelastic properties using the method as claimed in claim 37.
