We currently inhabit a four-dimensional world, encompassing three-dimensional space along with the temporal dimension. Consequently, the field of material research is progressing beyond the manipulation of material characteristics, shape, and spatial structure, entering the era of 4D material development which involves controlling the decomposition, shape transformation, property changes, and permanence of materials over time. Aligned with this contemporary trend, we are addressing critical societal issues through the development of various 4D materials, organized into six major themes.
The six themes comprise the Minimally Invasive/Biodegradable Medical Implants, aimed at minimizing the need for secondary surgery and reducing temporal/spatial constraints in medical services; the Zero-Waste/Eco-Friendly Electronic Materials, focused on creating materials that generate no waste and consume no energy resources; the Security/Intelligence Materials developing materials that leave no traces and can self-destruct at a desired time; the Material Reliability/Packaging, assisting in the long-term performance of desired functions; the Safety Diagnosis and Accident Prevention Technology, predicting and diagnosing the lifespan of materials in structures such as buildings; and the 3D Electronic Printing, enabling customized designs with various materials. Through six independent yet complementary research themes, we are leading the way in innovation in 4D materials.
