It is difficult to test the elastic modulus of the soft bio-anthropomorphic materials by using the general stretch-strain test method. With the equipment for a hardness testing system of bio-anthropomorphic materials and millesimal gauge, we introduce in this paper a compress-strain test method and carry out the related test-data curve-fitness. The test results indicate that this kind of method can be adopted in testing the elastic modulus of the soft bio-anthropomorphic materials and help to compare and distinguish the biomechanics equivalent between the tissues.

This paper is based on the research and analysis of the existing related measuring methods, and aimed at the characteristics of equivalent artificial soft materials, and it also proposes a new adaptable test method to measure elastic modules. The modules are based on capacitive gate transducer and micrometer which suits for soft materials. Based on this proposed method, a micro feed mechanism has been designed. The same strain of soft materials under compress test was realized, and the feasibility of this method by analyzing the test results was testified.
