Both origami and kirigami are the art of folding paper. Origami is the pure form of paper folding whereas kirigami, instead, involves not only folding, but cutting as well. In general, kirigami is much less restrictive geometrically. As a result, it greatly expands the application scope of origami. For example, pop-up books are made possible because of kirigami. Hence, for engineering applications, it is worth considering kirigami when origami does not offer solutions.

The theme of this talk is on origami and kirigami inspired novel deployable structures. I shall start by introducing a family of origami based deployable structures that are capable of shape change and have multiple stable states. The structures can be made reconfigurable because of that. The concept has been utilised to build a robotic limb that can lift or hold weights. Secondly, I shall present the conversion of a well-known single motion origami structure, the Miura-ori, to a dual motion reconfigurable one using kirigami. And finally, I shall discuss the role of kirigami in comparison with origami when the thickness of the sheet cannot be ignored. I shall present examples where the use of kirigami leads to the most compact folding without any voids, which are simply impossible in origami. My talk will focus on the kinematic aspect of these structures, and all examples utilise rigorous mathematical modelling and analysis, and they are validated by physical models.

I would hope that this talk could stimulate some interest from the audience in developing origami and kirigami structures and materials, and I am looking forward to any possibility of carrying out collaborative research.
