Summary
Functional polymeric materials are increasingly recognized as a foundational element for next-generation interfaces that connect biological systems, electronic devices, and robotic platforms. Owing to their intrinsic mechanical compliance, chemical adaptability, and broad functional tunability, polymeric materials enable stable, adaptive, and multifunctional interactions across soft, dynamic, and heterogeneous environments. This special issue aims to provide an inclusive platform for recent advances in polymer-based materials that support emerging interface technologies spanning bioelectronics, wearable systems, and robotics.
The scope of this issue encompasses the design, synthesis, processing, characterization, and application of functional polymeric materials for interfacial roles in advanced engineering and technological systems. Topics of interest range from fundamental studies on interfacial mechanics, physics, and material–interface interactions to applied research on polymers enabling stretchability, adhesion, conductivity, sensing, actuation, and environmental robustness. Contributions related to bio-integrated and implantable electronics, wearable and flexible devices, soft and hybrid robotic interfaces, and intelligent human–machine interaction systems are particularly encouraged, while broader interface-enabled applications are also welcome.
By bringing together interdisciplinary contributions from materials science, mechanics, chemistry, electronics, and robotics, this special issue seeks to illuminate emerging design strategies, establish structure–property–function relationships, and identify critical challenges and future opportunities for translating functional polymeric interfaces into practical technologies. The collection is intended to serve as a timely and comprehensive reference for researchers working on polymer-enabled interfaces across diverse application domains.
