Young’s Modulus and Tangential Modulus measurements of Hydrogel samples by Micro-Texture analyzer (YEONJIN S-Tech, Korea) Hydrogel samples are tested with 0.1 mm/sec compressive rate for the measurement of Young’s Modulus by Stress/Strain and Tangential Modulus by ΔStress/ΔStrain. 1.5 N Load cell was calibrated with 0.1 N standard weight and verified.3 mm metal cylinder probe was used. Hydrogel Sample 1. Hydrogel Sample 2. Hydrogel Sample 3 and 4
YEONJIN S-Tech, Texture Analyzer conforms with ASTM D2979 Ball Probe Tack Testing.
