“For invisibility cloaking, we need to both transmit and manipulate light in very precise ways, and that’s very difficult today,” said Rachel Goldman, professor of materials science, engineering and physics.
new holographic printing technique makes it possible to create the entire thing at once — in as little as a second or two, quickly producing the desired structure.
Researchers 3D-print WiFi-connected Objects That Don’t Need Power – The Objects Contain Antennas That Reflect Surrounding WiFi Signals.
“But the big challenge is how do you communicate wirelessly with WiFi using only plastic? That’s something that no one has been able to do before.” To do this, the team used things like 3D-printed springs, gears and switches that could be used to translate motion into antenna-transmitted information.
The process looks something like a hi-tech sewing machine weaving an emblem onto a garment.
But soon the pattern begins to rise and swell, and a nose, constructed using a bio-ink containing real human cells, grows upwards from the glass, glowing brightly under an ultraviolet light.
n research described in the journal Nature Photonics, the Turkey-based researchers have developed a 3D laser fabrication technique that deliberately creates the conditions for exploiting these interactions, known as nonlinear feedback mechanisms.
