Microfluidic In-Situ Measurement of Poisson’s Ratio of Hydrogels

  title={Microfluidic In-Situ Measurement of Poisson’s Ratio of Hydrogels},
  author={Jean Cappello and Vincent d'Herbemont and Anke Lindner and Olivia du Roure},
Being able to precisely characterize the mechanical properties of soft microparticles is essential for numerous situations, from the understanding of the flow of biological fluids to the development of soft micro-robots. Here, we present a simple measurement technique for determining Poisson’s ratio of soft micron-sized hydrogels in the presence of a surrounding liquid. This method relies on the measurement of the deformation, in two orthogonal directions, of a rectangular hydrogel slab…
