The electromagnetic properties of highly conductive gels are finally revealed

Complex fluids possess intermediary electromechanical properties, between those of solids and liquids. For the first time, an original metrological device has enabled physicists to carry out simultaneous measurements of the electric elasticity and conductivity of these highly conductive fluids, both at rest and in motion, thus highlighting rearrangements of the material’s microstructure under small macroscopic deformations.
