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.
Optimization Modeling Helps Control Electricity Supply Continuity in Brazil
Optimization research provided by Georgia Tech helped improve a computer algorithm used to ensure that electricity generation meets the demand in Brazil. The country relies heavily on hydroelectric facilities for its electricity.
August 15, 2013 — A Georgia Tech Research Institute (GTRI) team is developing a new generation of advanced radio frequency (RF) jammer technology. The project, known as Angry Kitten, is utilizing commercial electronics, custom hardware development, novel machine-learning software and a unique test bed to evaluate unprecedented levels of adaptability in EW technology.
August 12, 2013 — An experimental health information exchange being tested in the north Georgia city of Rome is helping breast cancer patients access their health information and stay in touch with their doctors. The program, MyJourney Compass, is designed to help patients become more involved their health care decisions.
August 11, 2013 — Georgia Tech researchers want to put your signature up in lights. Using thousands of nanometer-scale wires, the researchers have developed a sensor device that converts mechanical pressure – from a signature or a fingerprint – directly into light signals that can be captured and processed optically.
July 9, 2013 — By using gelatin-based microparticles to deliver growth factors, researchers are creating three-dimensional structures from stem cells and reducing the use of growth factors needed to promote differentiation.
July 9, 2013 — By studying rapidly evolving bacteria as they diversify and compete under varying environmental conditions, researchers have shown that temporal niches are important to maintaining biodiversity in natural systems. The research is believed to be the first experimental demonstration of temporal niche dynamics promoting biodiversity over evolutionary time scales.
June 19, 2013 — Using clouds of ultra-cold atoms and a pair of lasers operating at optical wavelengths, researchers have reached a quantum network milestone: entangling light with an optical atomic coherence composed of interacting atoms in two different states. The development could help pave the way for functional, multi-node quantum networks.
June 18, 2013 — Antenna technology originally developed to quickly send and receive information through a software-defined military radio may soon be used to transmit ocean data from a wave-powered autonomous surface vehicle. The technology, the lowest-power method for maintaining a satellite uplink, automatically compensates for the movement of the antenna as the boat bobs around on the ocean surface.
June 11, 2013 — Using star-shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures – including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals.
June 6, 2013 — A new set of long-term climate records based on cave stalagmites collected from tropical Borneo shows that the western tropical Pacific responded very differently than other regions of the globe to abrupt climate change events. The 100,000-year climate record adds to data on past climate events.
June 4, 2013 — A new study shows that similar timing patterns are used by many swimming animals to produce undulatory swimming motions. Scientists have created a simple model of these patterns and applied it to understand the connection between electrical signals and body movement in the sandfish, a lizard.
