Origami Without Fingers

What has Been Achieved:

A new way to control the precise folding geometry of 2D sheets has been conceived and validated by a combination of first principles and empirical modeling.

Importance of Achievement:

It is challenging to precisely control fold geometry at the nanoscale. Such folds enable the production of new 3D structures from 2D sheets, with potential for new functionalities. This work shows how a very straightforward and familiar process – doping – can control the geometry of folds.

Unique Features of the MIP That Enabled Project:

Close collaborative interactions across different disciplines of theory and simulation.
