Shape-shifting metamaterials

The research team leader, Professor Jiyun Kim of the Department of Materials Science and Engineering at the Korea Advanced Institute of Science and Technology (KAIST), said that inspired by octopuses, the Korean scientists created “a metamaterial synthesis system that allows for incremental and inverse tuning of various mechanical information, by translating encoded pattern information into distinct rigid states of mechanical pixels.”

Digitally Programmable Metamaterials - KAIST

Digitally programmable metamaterials possess remarkable capabilities, including shape and memory changes, and cross-sectional ratios that can deform under compressive loads. Furthermore, the new material exhibits application-oriented functions, such as the ability to absorb energy and distribute pressure in an adjustable and reusable manner. By inputting specific digital commands, the material can operate adjacent LED switches, enabling precise control of force pathways. This metamaterial is also compatible with a range of devices and utilities, as well as artificial intelligence technologies. According to the researchers, this material surpasses the limitations of existing materials and has significant potential applications in fields requiring rapid adaptability, particularly in robotics.
