Abstract: Electromechanical (EM) coupling is a nearly universal property for all biological systems. It is proposed that the EM coupling may contribute to the structural, mechanical, and physiological behaviors from cell to tissue levels. But the exact roles and working mechanisms of the EM coupling in biological systems are still mysterious. In this research work, the EM coupling behaviors of mollusk shells were systematically studied, including biopiezoelectricity and bioferroelectricity. Mollusk shells are well known for their outstanding mechanical properties, the coexistence of high strength and high toughness. The main results discussed in this thesis include the hierarchical structures, nanoscale elasticity mappings, and biopiezoelectric and bioferroelectric properties of abalone and clam shells. The external stress and temperature caused property changes were also reported. It was found that the EM couplings observed in mollusk shells may also play an important role in the shell toughening mechanism.
