Shape-changing metamaterial

Engineers from the University of Bristol in Britain have developed a new shape-changing metamaterial using Kirigami — an ancient Japanese art of cutting and folding paper to obtain 3D shapes. Metamaterials are materials engineered to produce properties that do not occur naturally and they are used to make artificial electromagnetic and vibration absorbers and high-performance sensors. The research, developed within a Ph.D. programme run by the University’s EPSRC Centre for Doctoral Training in Advanced Composites for Innovation and Science, was published today in Scientific Reports. These metamaterials change shape seamlessly, exhibit large variations in mechanical performance.
