Our objective was to enhance the precision of force measurements and improve sample visibility during compression testing. We compared the performance of our innovative 3D-printed confined compression setup to a conventional setup by performing stress relaxation testing on hydrogels with variab...
Energy-dissipation elastomers relying on their viscoelastic behavior of chain segments in the glass transition region can effectively suppress vibrations and noises in various fields, yet the operating frequency of those elastomers is difficult to control precisely and its range is narrow. Here, we repo...
Xerogel SPH-1 adsorbent water spheres (1441 ± 11μm; sphericity of 0.98; ΔV/V ∼87%; soft gels (Leonard, 1997) with mechanical resistance to compression of 24.7 ± 1.9 MPa) remain intact, while xerogel SPH-2 adsorbent water spheres (∼1732μm; sphericity of 0.98; ΔV/V ∼...
Moreover, advancement in subcutaneous drug delivery requires effective tissue mimics such as hydrogels for which similar gaps of poroelastic data exist. Porcine subcutaneous samples and gelatin hydrogels were tested under confined compression at physiological conditions and strain rates of 0.01%/s in 5% ...
