Professor Jennifer Curtis 'painting' the 30-micron Mini Lisa

Arguably the world’s most famous painting, da Vinci's Mona Lisa has now been copied onto the world’s smallest canvas at the Georgia Institute of Technology. Associate Professor Jennifer Curtis' "Mini Lisa" is one-third the width of a human hair, with details as small as one-eighth of a micron. Mini Lisa demonstrates the flexibility of a new nanolithography technique that can vary the surface concentration of molecules on very small portions of a substrate.  Read More

The new fluid-repellent paper was developed at the Georgia Institute of Technology

Scientists at the Georgia Institute of Technology have produced a new kind of paper that repels a range of liquids, including water and oil. The new paper shows significant promise as an affordable and recyclable packaging material, but it's the paper’s potential as an inexpensive biomedical diagnostic tool that has really got the researchers excited.  Read More

For years now, scientists across the globe have strived to find a method that gives robots an accurate sense of touch, and with good reason. A robot with an improved ability to feel would be better equipped to identify objects, judge its movements with greater care, and perform more tasks overall. In the latest step towards that goal, researchers at Georgia Tech have crafted a new type of touch-reactive material that's sensitive enough to read fingerprints and could provide robots with a sense of touch that resembles our own.  Read More

The new solar cells can be easily recycled in water at room temperature

Researchers at Georgia Institute of Technology and Purdue University have developed new solar cells based on natural substances derived from plants, including trees. The organic solar cells have an efficiency of 2.7 percent – a new high for cells on substrates derived from renewable raw materials – and can be easily recycled.  Read More

If you’ve seen even a few minutes of any documentary on sharks, then chances are you’ve seen a remora. They’re the smaller fish that hitch rides on sharks by sucking onto them. Not only are the remoras able to achieve a seal against their hosts’ rough, sandpaper-like skin, but they also don’t appear to harm that skin in the process. Researchers from the Georgia Tech Research Institute are now studying how the remoras manage this, in hopes of applying their findings to the development of next-generation adhesives.  Read More

Even those who consider themselves particularly coordinated will no doubt have been guilty of a misplaced tap here or a badly timed swipe there when using touchscreen devices. But spare a thought for children with fine motor impairments who are essentially excluded from the touchscreen device world and all its educational, entertainment and social benefits. A new device called Access4Kids aims to bring this world within reach of such users.  Read More

Georgia Tech researcher Zhong Lin Wang holds the components of a new self-charging power c...

Systems that convert kinetic energy into electric energy have made great strides in recent times, from mobile phone charging bicycle dynamos to tiles that turn footsteps into electrical energy. Recently researchers at Georgia Institute of Technology have come up with what they believe is a more efficient approach – a self-charging power cell that directly converts mechanical energy to chemical energy and stores the power for release as an electrical current.  Read More

Georgia Tech's networked robots coordinate their movements to play music on a simulated pi...

Researchers at Georgia Tech's GRITS Lab are working with swarms of mini robots that communicate with one another to work effectively. The aim of the research is to create networks that can be controlled by inputting instructions to a single robot. Beginning with a leader, each robot communicates with its nearest neighbors until the instructions have been shared across the network. In an effort to create the most efficient "follow-the-leader" algorithms, the researchers are getting the robot swarm to play musical notes on a simulated piano.  Read More

A test subject teaches the PR2 robot how to fold a t-shirt through demonstration

Don't believe what the sci-fi movies tell you: when it comes to understanding our world, robots are stupid. Like computers, robots only do what we program them to do. And that's a big problem if we're ever going to realize the dream of practical robot helpers for the masses. Wouldn't it be great if anyone could teach a robot to perform a task, like they would a child? Well, that's precisely what Maya Cakmak has been working on at Willow Garage.  Read More

The TechJect Dragonfly fits in the palm of a hand

Given their impressive flight capabilities, it’s not surprising to see researchers turning to the world of flying insects for inspiration when developing new kinds of micro UAVs. With their ability to both fly at high speeds and hover, the dragonfly would seem an obvious candidate for biomimicry. But with the exception of the DelFly, we hadn’t seen many attempts to model a micro UAV on the dragonfly’s four wing design. That could be changing with a multi-disciplinary team from Georgia Tech having developed a robotic four-winged ornithopter called the TechJect Dragonfly that fits in the palm of a hand and combines the flight capabilities of a quadricopter, helicopter and fixed wing aircraft in one.  Read More
