Tensegami(tensegrity and origami) structures are especially interesting when they acquire flexibility from rod constraints based on tensegrity structure’s exterior.
For the atomic design thinking, I was brainstorming the combination of tensegrity structures with folded or banded plane.
I prepared 10*10 papers, 8*8 cottons, thin straws, pins.
The straws work as rod and pin work as joint, papers work as cable in tensegrity.

Today, I tried to fold a paper and made a shape for tensegrity dome.
And I folded like this.
It seems similar with Temporärer Pavillon in Noda.
So this design can improve like the shape below.
So this can be foldable and lightweight.
Today’s Developed Work

(2) two tips
(3) three tips
The most crucial evolutionary feat to allow for bird flight, the wing is a system in which the skeleton and feathers act together to allow for a high lift-to-weight ratio. The wing skeleton is particularly lightweight; unlike terrestrial vertebrates’ marrow-filled bones, most bird wings are composed of hollow bones, similar to the bones of bats and pterosaurs. [1]
All birds have certain coinciding bone and feather features. In most birds the skeleton extends only half-way from the shoulder to the wing tip and therefore the majority of the area of the wing is supported by flight feather. Wing flight feathers include primaries that branch from the hand skeleton and secondaries that attach to the edge of the ulna. They are able to hinge up and down relative to the ulna through flexible attachment. [2]

First, I started to make a wing model which are folding and straightening.
I followed the structure of umbrella.

And then, I developed with the structure of tensegrity.

What is Tensegrity?
Tensegrity is a contraction of tensile integrity, and tension is omnidirectionally coherent. The concept of tensegrity evolved from a single-layer form which is not applicable to double-layer form, representatively, of non-contiguous strut configuration by Emmer-ich and Han or and of contiguous strut configuration by Motro.
How to design Tensegrity Wing?
First, I need to know what is the wing’s structure. So, I started to analyze the wing of Bat.
A sequence of images from typical wingbeat of Cynopterus bronchitis in slow flight. These lateral views show some portion of the complexity of 3D form of the wing during flight.
Bat with anatomical markers on body and wing bones and skin.
The bat’s wings are applicable in combination with the structure of tensegrity.
