This paper reports the realization of harvesting acoustic energy based on topological interface mode a 1D phononic crystal (PC) tube. When incidence sound is at eigenfrequency mode, localized that provides feasibility for realizing (AEH) by using piezoelectric cantilever plate. The results indicate there 66 times pressure gain and peak generated voltage observed mode. study opens new avenue AEH modes PCs.
