Scientists at MIT and Harvard have invented self-folding smart fiberglass sheets that can crease themselves into origami airplanes and boats.
It’s a far cry from previous programmable matter research we’ve seen, which works at the nanoscale to create scaffolds and gears.
The fiberglass sheets are about a half-millimeter thick and made of half-inch-wide triangular tiles. They can be made at a larger scale, enabling machines that can fold, Transformer-like, into any number of objects.
from Harvard Medical School:
By emulating nature’s design principles, a team at Harvard’s Wyss Institute for Biologically Inspired Engineering, Harvard Medical School and Dana-Farber Cancer Institute has created nanodevices made of DNA that self-assemble and can be programmed to move and change shape on demand.
In contrast to existing nanotechnologies, these programmable nanodevices are highly suitable for medical applications because DNA is both biocompatible and biodegradable.
The work appears in the June 20 advance online Nature Nanotechnology.
Paper is not dead. Books, magazines and other printed materials can now be connected to the digital world, enriched with additional content and even transformed into interactive interfaces.
Conversely, some of the screen-based interfaces we currently use to interact with digital data could benefit from being paper-based or make use of specially designed material as light and flexible as paper.
In a near future, printed documents could become new ubiquitous interfaces for our everyday interactions with digital information. This is the dawn of paper computing.

This is the next step in my attempt to make a Sarrus linkage based 3D printer. The idea is to have a cartesian mechanism without those long rods and bearings.
I built three of the Mark III and mounted them in a x-y arrangement as shown. They can move over a square about 105 mm wide, and someday may carry an extruder. They are driven by DC motors taken from inkjet printers. These motors are driven in a servo arrangement using quadrature optical encoders and optical strips removed from the same printers.
