Abstract：
This presentation talks about the deformable electronics and metamaterials of the batteries by Origami and Kirigami - Fusion of arts. The first part demonstrates the fabrication of origami electronics that has superb flexible, stretchability and foldability. The fabrication processes here represent an example to utilize mainstream high-temperature processes to fabricate high-performance stretchable electronics. Three examples, namely origami solar cells, origami lithium ion batteries, and kirigami batteries will be presented. The second part describes mechanical metamaterials created by origami in terms of their basic geometric and stiffness properties, as well as load bearing capability. A periodic Miura-ori pattern and a non-periodic Ron Resch pattern will be presented. Unexceptional coexistence of positive and negative Poisson’s ratio are found for Miura-ori pattern, which are consistent with the interesting shear behavior and infinity bulk modulus of the same pattern. Unusually strong load bearing capability of the Ron Resch pattern will be discussed due to the unique way of folding. The third part presents the fabrication of microscale origami. This work paves the way to explore new and exciting engineering applications of origami.
