"Master’s student Muhammad Abu Hurairah (아부) from Prof. Jihong Hwang’s Smart Machining Laboratory, during his assistantship in Prof. Seung Hyun Lee’s Experimental Solid Mechanics Laboratory, has published the results of a completed research project in the top-tier peer-reviewed journal Materials & Design (Impact Factor: 7.9). The research team consisted of Muhammad Abu Hurairah (아부) and Minwook Park (박민욱), a postgraduate student in the Experimental Solid Mechanics Laboratory, under the supervision of Prof. Seung Hyun Lee. The study was motivated by the growing demand for improved mechanical control of polydimethylsiloxane (PDMS), an extremely flexible, transparent, and adhesive material widely used in biomedical devices and stretchable electronics. A comprehensive literature review revealed that, although previous studies have explored modifications in chemical composition and surface properties, limited research has focused on optimizing structural and design parameters to control the mechanical behavior of PDMS-d systems. This gap formed the foundation of the present research. The paper presents a novel strategy for engineering stretchable electronic systems using Re-entrant Auxetic Cellular Structures (RACS) to achieve a negative Poisson’s ratio. The study specifically identifies horizontal rib thickness as the most influential parameter governing mechanical response and tunability. To validate the proposed design, the researchers implemented a three-stage methodology consisting of finite element analysis (FEA), experimental characterization of fabricated PDMS samples, and integration into multi-cell array structures to uate scalability and structural stability for wearable device applications. The developed methodology offers a cost-effective and efficient approach for improving the mechanical controllability of PDMS-d auxetic structures, particularly for transparent and stretchable electronic devices.
