ElastoSens Bio uses vibrations to measure soft matter viscoelasticity non-destructively and with no contact. Viscoelasticity Testing of Bilayered Materials (VeTBiM) is the patented technology behind the ElastoSens Bio.
VeTBiM consists in measuring the free response of a bi-layered system comprised of a sample over a flexible membrane to a vibrational impulse. The sample is contained into a solid sample holder having a flexible membrane at its bottom. During a tests, this sample holder is firmly attached to a vibrating unit inside the instrument. It can be removed from the instrument between tests and replaced as needed.
How does it work?
When tested on the ElastoSens Bio, the sample and the flexible membrane are submitted to a gentle vibration of a few micrometers that is applied to the whole sample holder. This excitation triggers a slight vibration in the sample and the membrane. The membrane displacement is remotely measured by a laser optical probe. A built-in ultrasonic height probe measures the sample height to accurately capture in real time any volume change of the sample that may be caused by swelling or degradation.
