\u25a1 Professor Kyung-In Jang\u2019s research team from the Department of Robotics and Mechatronics Engineering at DGIST (President Kunwoo Lee) has succeeded in developing a highly stable stretchable electronic device, which overcomes the mechanical limitations of conventional inorganic materials and enhances their stretchability and durability. In collaboration with Professor Taeho Park\u2019s team from the Department of Chemical Engineering at POSTECH (President Seong-Keun Kim), the research team has developed a stretchable hybrid polymer and applied it to electronic devices, enabling them to operate stably even under deformation or external impacts. This technology is expected to be used in various industries, such as displays, healthcare, and wearables.<\/p>\n

\u25a1 The \u201cstretchable electronic device\u201d technology is a promising technology applicable to various industries, such as displays, wearables, and healthcare. However, when subjected to deformation, such as stretching and bending, or external impacts, maintaining stable electrical functionality in these components becomes challenging. To address this issue, various research efforts are underway. Against this backdrop, the DGIST-POSTECH joint research team has developed a \u201cstretchable hybrid polymer\u201d and introduced a new strain isolation strategy to integrate [1]stretchable inorganic electronic devices with high efficiency, creating a new \u201cstretchable electronic device\u201d that operates stably even under deformation or external impacts.<\/p>\n

\u25a1 First, the research team developed the \u201cstretchable hybrid polymer\u201d through \u201cInterpenetrating Polymer Network (IPN) cross-linking.\u201d The IPN is a 3D polymer structure formed by physically and chemically cross-linking two or more polymers, maintaining each polymer\u2019s features while reinforcing each other. It can maintain high stability and performance even under deformation by inducing physical entanglement between polymers, which forms an excellent mechanical interface. The research team created a \u201cstretchable hybrid polymer\u201d using silicone-based polymers with different elastic moduli, polydimethylsiloxane (PDMS) and polyurethane (PU).<\/p>\n

Subsequently, the team built a substrate with the developed stretchable polymer and combined it with the high-efficiency stretchable electronic component made from inorganic materials to complete the \u201cstretchable electronic device.\u201d The newly created electronic device is designed to distribute strain that occurs at a single point when subjected to stretching or bending, thus reducing mechanical strain on the device and maintaining its high stability. This significantly reduces physical damage and performance degradation that can occur in existing stretchable electronics.<\/p>\n

Professor Kyung-In Jang from the Department of Robotics and Mechatronics Engineering said \u201cWe are pleased to have developed the stretchable electronic device system that maintains the performance of inorganic materials, which are mechanically vulnerable, even under various deformations and physical damages.\u201d He also added, \u201cWe confirmed the system\u2019s stability in applications such as stretchable micro-light emitting devices and heaters through verification, and we will further enhance this research to apply it in various industries such as healthcare and wearables as well as stretchable displays.\u201d<\/p>\n
