NEW PUBLICATION: Interface-governed electromechanical coupling in bioinspired hierarchical piezoelectric poly(L-lactide) architectures

Our PhD student Martina Žabčić with our research group of the Advanced Materials Department (K9), at the Jožef Stefan Institute, in collaboration with researchers from the Department of Surface Engineering, Jozef Stefan Institute (F4) and Condensed Matter Physics Department (F5) and University of Maribor, Faculty of Mechanical Engineering, has published a new article in Materials Horizons entitled: Interface-governed electromechanical coupling in bioinspired hierarchical piezoelectric poly(L-lactide) architectures.

This work presents a new design for soft piezoelectric materials in which interface act as active element governing electromechanical coupling. By engineering plasma-activated interfaces within layered piezoelectric structures, shear deformation is concentrated and piezoelectric response is amplified beyond that of individual components.

This interface-driven effect extends to biological systems, where, under non-invasive ultrasound stimulation, an extracellular-matrix-mimetic surface enables effective electrical communication with cells, enhancing adhesion, proliferation, and cytoskeletal organization.
