An effective approach for an embedded piezo diagnostic layer into thick composite material is presented. The effectiveness of the approach is assessed in comparison to the surface-mounted layer. The proposed manufacturing alleviates difficulties asso
Self-healing polymeric materials are at the state-of-art of advanced materials for the last three decades. Among the three self-healing approaches, intrinsic, vascular, and capsule-based, the most easily applicable method is that of the encapsulation
