Abstract—A Polymer gel mimicked human soft tissue was being fabricated using a monomer named 2-Hydroxyl-Ethyl-Acrylate (HEA) with the present of gelatin. The readymade gel which is the concentration for HEA fixed at 5% was then undergoes an ultrasonic evaluation to test for the propagation of sound speed through it. Sonic Waves Analyzer is absolutely the most accurate technique to determine the aims (changes of speed as function of polymer structure /stiffness over time). The fixed frequency of transducers involved is at 500 kHz by using the seismic reflection concept. In the observation of relationship between the ultrasound propagation speeds as the day increased, the propagation speed still varies between 1390 to 1500 m/s which is still in the range of speed of sound for human tissue.
