Abstract
Soft materials have distinct function and their characteristics are different from those of metals. Until now, we have developed the active BZ gels. BZ gels can oscillate in volume using non-linear chemical reaction and be innovative materials for medical devices. In previous study, it was found that the BZ gels could generate the large deformation under external load. Herein, we analyzed the mechanical behavior of pre-stretched BZ gels. For this purpose, we developed new tensile system for gels. We measured tensile force of BZ gels in swelling state and shrinking state. We could observe stress oscillation of pre-stretched BZ gel.
