Electromechanical behavior of auxetic piezoelectric cellular solids

Cellular solids and piezoelectrically active materials are important to a wide range of engineering applications in their own right. However, the integration of these two classes of materials into a hybrid porous electroactive composite promises to result in materials with a unique combinations of properties. In this work a multifunctional electroactive cellular material engineered by employing piezoelectrically active constituents in an auxetic and topologically tailored cellular solid is proposed, and its unique properties are highlighted using finite element analysis.
