Fabrication method of functional micro/nano structures over large-area, flexible and high curvature surfaces, by drawing a fiber from a preform

Fabien Sorin, Wei Yan, Alexis Gérald Page, Yunpeng Qu, Dang Tùng Nguyen

The method for drawing a fiber with a textured surface comprises the following steps: - forming of a preform from which the fiber is to be drawn with a textured surface; - addition of an outer layer to the textured preform to preserve the shape of the text ...

Double-layered timber plate shell. International Journal of Space Structures

Yves Weinand, Mark Pauly, Christopher Werner Matthias Robeller, Mina Konakovic Lukovic, Mira Dedijer

This article presents a new lightweight construction system for doubly curved shells made from timber plates, inspired by the masonry vaults of Eladio Dieste. The system was developed for a specific case-study project, and general applications to other fre ...

Smooth Shapes with Spherical Topology: Beyond Traditional Modeling, Efficient Deformation, and Interaction

Michaël Unser, Daniel Andreas Schmitter

Existing shape models with spherical topology are typically designed either in the discrete domain using interpolating polygon meshes or in the continuous domain using smooth but non-interpolating schemes such as subdivision or NURBS. Both polygon models a ...

Multi-material micro-electromechanical fibers with bendable functional domains

Fabien Sorin, Wei Yan, Alexis Gérald Page, Yunpeng Qu, Marco Volpi

The integration of increasingly complex functionalities within thermally drawn multi-material fibers is heralding a novel path towards advanced soft electronics and smart fabrics. Fibers capable of electronic, optoelectronic, piezoelectric or energy harves ...

Fabrication of slender elastic shells by the coating of curved surfaces

François Gallaire, Pedro Miguel Nunes Pereira de Almeida Reis, Gioele Mariano Nicolò Balestra, Pierre-Thomas Paul Brun

Various manufacturing techniques exist to produce double-curvature shells, including injection, rotational and blow molding, as well as dip coating. However, these industrial processes are typically geared for mass production and are not directly applicabl ...

Beyond Developable: Computational Design and Fabrication with Auxetic Materials

Mark Pauly, Sofien Bouaziz, Bailin Deng, Mina Konakovic Lukovic

We present a computational method for interactive 3D design and rationalization of surfaces via auxetic materials, i.e., flat flexible material that can stretch uniformly up to a certain extent. A key motivation for studying such material is that one can a ...

Viruses at solid-water interfaces: A systematic assessment of interactions driving adsorption

Tamar Kohn, Anne Thérèse Sigstam, Meret Aeppli, Antonius Magdi Hakeem Armanious

Adsorption to solid-water interfaces is a major process governing the fate of waterborne viruses in natural and engineered systems. The relative contributions of different interaction forces to adsorption and their dependence on the physicochemical propert ...
