On electromechanical behaviour of frog sartorius muscles.

Considering coupled electromechanical properties of biological soft tissues is an innovative characterization of most soft tissues, this paper reports our experimental observation on electromechanical properties of frog sartorius muscles including the experiment design, test sample preparation, test results and analysis. The experiment results indicate that the electric potential generated in the frog muscle tissues varies with external mechanical loadings. The electric voltage increases with an increase in the frog muscles deformation. This phenomenon is found to be loading cycle and frequency dependency. The experiment results demonstrated that frog muscle tissues can convert their mechanical deformations into electrical signals significantly. The experiment work here is an essential step in understanding the complex electromechanical behaviour of biological soft tissue. It may lead to further research in determining quantitatively the complex electromechanical properties of biological soft tissues.
