Stretchable and foldable electronic displays

Stretchable and foldable silicon integrated circuits.

We have developed a simple approach to high-performance, stretchable, and foldable integrated circuits. The systems integrate inorganic electronic materials, including aligned arrays of nanoribbons of single crystalline silicon, with ultrathin plastic and elastomeric substrates. The designs combine multilayer neutral mechanical plane layouts and "wavy" structural configurations in silicon compl...

Stretchable inorganic-semiconductor electronic systems.

Cutting edge: thin, lightweight, foldable thermochromic displays on paper.

In this issue of Lab on a Chip, Siegel et al. present a novel method for electronic control of displays on paper substrates. The authors micropatterned electrically conductive wires on one side of the paper, and coated thermochromic ink on the other side. This combination of materials allows a clever operation: as current flows through the wires to achieve localized resistive heating, dye in th...

Mechanical Characterization of Flexible and Stretchable Electronic Substrates

1. Flexible substrates can be subdivided in two classes: Substrates that allow for inextensial bending only and substrates that due to the larger stretchability allow for more arbitrary bending. The first group of flexible substrates can only be applied on surfaces with zero Gaussian curvature. The application of the second group of flexible substrates is more general. They can also be applied ...

Foldable Joints for Foldable Robots

Print-and-fold manufacturing has the potential to democratize access to robots with robots that are easier to fabricate using materials that are easier to procure. Unfortunately, a lack of understanding about how motion can be achieved by folding hinders the scope of print-and-fold robots. In this paper, we show how the basic joints used in robots can be constructed using print-and-fold. Our pa...
