University of Stuttgart researchers used 3D printing to fabricate a tiny three-lens camera that fits on the end of an optical fiber no wider than two human hairs. Eventually, the technology could lead to a new kind of very thin endoscope for looking inside the human body. According to the researchers, the camera delivered "high optical performances and tremendous compactness." From Phys.org:
(The camera) can focus on images from a distance of 3.0 mm, and relay them over the length of a 1.7-metre (5.6-foot) optical fibre to which it is attached.
The "imaging system" fits comfortably inside a standard syringe needle, said the team, allowing for delivery into a human organ, or even the brain.
"Endoscopic applications will allow for non-invasive and non-destructive examination of small objects in the medical as well as the industrial sector," they wrote (in their scientific paper).
Below, the lens (blue) was fabricated directly on the optical fiber (red). The fiber and camera are emerging from a hollow, 27 gauge syringe needle:
Researchers at Telecom Paris have developed an artificial skin that responds to stroking, pinching, tapping, and tickling. To demonstrate it, they covered a mobile phone with the skin and showed how it could work as a back-of-the-device interface. The video also shows how the material can be used to give robots a skin that “feels” […]
Beware the rogue .wav file.
Canadian camouflage developer HyperStealth Biotechnology Corp released a series of videos demonstrating their new “patent-pending” “Quantum Stealth Light Bending Material (Invisibility Cloak).” Here is HyperStealth’s technical video about the technology and their press release.
Everybody could use a little improvement, especially those of us on the hunt for new careers. Each job requires a different set of skills, and that list can change from year to year or even month to month as new technologies emerge. When you’re in that race and need to learn fast, the old model […]
In recent years, natural language processing technology and language translation technology have advanced greatly. The trouble is, language translation software typically comes in the form of apps. And while your mileage may vary on their usefulness, they share one thing in common: a serious drain on the battery for your smartphone, the very thing you’ll […]
