11. Implications and applications

This week I wanted to explore more on the week 8 results, the auxestic bistable pattern.

In collaboration with a Belgian designer Idylle design we decided to start to create a leather bag with the pattern on the center.

The aim was to get a bag that was stretchable and change size and pattern depending on what is put inside.

As a final project I would like to develop stretchable clothes that could fit most of people just by using auxetic pattern cut in strategic position.

This pattern only deforms when it's under tension and get to an other state. The pattern expands under longitudinal strain and contracts when compressed. If the pattern is applied on strategic zones this could help getting an adaptive garment. Research on auxetic pattern

Active auxetic Heat-Active Auxetic Materials, developed at MIT’s Self-Assembly Lab, are materials that exhibit auxetic behavior when exposed to heat.

Charles Kaisin is a belgian designer who developped a leather bag cut with an origami pattern.

The bag is flat and the pattern opens when you wear it.

Test with designer

I worked with a fashion designer, Idylle design, and we cut a big peace of leather in order to make a bag. We worked on the size of the pattern and on the laser cut setting.

This is the leather piece after the cut.

The designer is going to work on this piece in order to make a bag with it.

Personal test

I made some tests with the bistable auxetic pattern cut on recovered fabrics for the final project.

It is hard to find the right parameters with fabrics in order to get a stretch result that do not break. The first try is very nice and stretch, but broke, second one in harder but not so stretch and adaptative.


Unisize and adaptative clothes are a good way to reduce waste and stocks.

Pros Cons
For the brands For the customer For the brands For the customer
Less return for non-fit Long lasting clothes (can adapt to the different life stages) Harder to design Bored with the cloths
Stock easier to manage Innovative design Transparent zones to manage

Fabrics limits

The auxetic pattern is laser cut and does not work with all fabrics or material.

It's working with leather and scuba.

Could be tried with biomaterials.
