Graphene-Based Nano-Antennas May Enable Networks of Tiny Machines
Researchers are taking advantage of the unique properties of graphene to design tiny antennas that may open the possibility for networks of nanometer-scale machines. Graphene could generate a type of electronic surface wave that would allow antennas just one micron long and 10 to 100 nanometers wide to do the work of much larger antennas.
Harvesting Electricity: Triboelectric Generators Capture Wasted Power
Researchers are developing a family of generators that provide power for portable electronic devices and sensors by harnessing the triboelectric effect to capture mechanical energy that would otherwise be wasted.
Clinical Trial Shows Tongue-Controlled Wheelchair Outperforms Popular Wheelchair Navigation System
In a new clinical trial, individuals with paralysis were able to use a tongue-controlled technology to access computers and execute commands for their wheelchairs at speeds that were significantly faster than those recorded in sip-and-puff wheelchairs, but with equal accuracy. This study is the first to show that the wireless and wearable Tongue Drive System outperforms sip-and-puff in controlling wheelchairs.
Scientists Work to Engineer an Injectable Therapy for Rotator Cuff Injuries
Researcher are attempting to engineer an injectable therapy for the shoulder’s supraspinatus tendon, a rotator cuff tendon that is commonly torn in sports. When the tendon is damaged, the body makes things worse by activating enzymes that further break down the tendon. The scientists hope to develop an injectable compound that would deliver an inhibitor capable of blocking these enzymes, thereby reducing the severity of the injury or even healing the tissue.
Sticky Business: Magnetic Pollen Replicas Offer Multimodal Adhesion
Researchers have created magnetic replicas of sunflower pollen grains using a wet chemical, layer-by-layer process that applies highly conformal iron oxide coatings. The replicas possess natural adhesion properties inherited from the spiky pollen particles while gaining magnetic behavior, allowing for tailored adhesion to surfaces.
Evidence Found for Granite on Mars
Large amounts of a mineral found in granite, known as feldspar, were found in an ancient Martian volcano. The location of the feldspar also provides an explanation for how granite could have formed on Mars, according to a new study in Nature Geoscience.
August 12, 2007 — Researchers at the Georgia Institute of Technology have received a Defense Advanced Research Projects Agency (DARPA) award to participate in a multi-university research center that will develop a computer-aided design (CAD) environment for micro-electromechanical systems (MEMS) and nano-electromechanical systems (NEMS).

July 20, 2007 — As part of an effort to increase job-safety training and awareness among younger Americans, scientists from the Georgia Tech Research Institute (GTRI) have joined with the U.S. Occupational Safety and Health Administration (OSHA) and other groups to introduce health and safety training to Georgia high schools.
July 20, 2007 — New research at the Georgia Institute of Technology could soon make that tangle of wires under desks and in data centers a thing of the past. Scientists at the Georgia Electronic Design Center (GEDC) at Georgia Tech are investigating the use of extremely high radio frequencies (RF) to achieve broad bandwidth and high data transmission rates over short distances.
June 20, 2007 — In a report published in the journal Geophysical Research Letters, researchers describe why a July 2006 tsunami caught beachgoers in Java, Indonesia by surprise. A low tide and wind-driven waves disguised the signs of receding water, and even the earthquake that caused it didn’t create the usual signs.
