Researchers develop world’s thinnest electric generator

October 15, 2014 -- Researchers have reported the first experimental observation of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide (MoS2), resulting in a unique electric generator and mechanosensation devices that are optically transparent, extremely light, and very bendable and stretchable.

Oliver Brand Assumes Top Post at Institute for Electronics and Nanotechnology

August 14, 2014 -- Oliver Brand, a professor in the Georgia Institute of Technology's School of Electrical and Computer Engineering, has been named executive director of the Institute for Electronics and Nanotechnology (IEN), one of nine interdisciplinary research institutes (IRIs) at Georgia Tech.

Agile Aperture Antenna Tested on Aircraft to Survey Ground Emitters, Maintain Satellite Connection

July 9, 2014 -- The Georgia Tech Research Institute’s software-defined, electronically-reconfigurable Agile Aperture Antenna (A3) has now been tested on the land, sea and air. Department of Defense representatives were in attendance during a recent event where two of the low-power devices, which can change beam directions in a thousandth of a second, were demonstrated in an aircraft during flight tests.

Graphene is Only as Strong as its Weakest Link: Experiments Determine Real-world Limits of Two-dimensional Carbon

April 29, 2014 -- Research laboratories at Rice University and Georgia Tech have tested the fracture toughness of graphene for the first time by making and measuring "pre-cracks" under stress.

Neuromorphic Computing “Roadmap” Envisions Analog Path to Simulating Human Brain

April 16, 2014 -- Electrical engineers at the Georgia Institute of Technology recently published a "roadmap" that details innovative analog-based techniques that could make it possible to build a practical neuromorphic computer that mimics the brain's operation.

Self-Assembled Silver Superlattices Create Molecular Machines with Hydrogen-Bond “Hinges” and Moving “Gears”

April 6, 2014 -- A combined computational and experimental study of self-assembled silver-based structures known as superlattices has revealed an unusual and unexpected behavior: arrays of gear-like molecular-scale machines that rotate in unison when pressure is applied to them.

Heat-Conducting Polymer Cools Hot Electronic Devices at 200 Degrees C

March 30, 2014 -- By harnessing an electropolymerization process to produce aligned arrays of polymer nanofibers, researchers have developed a thermal interface material able to conduct heat 20 times better than the original polymer -- operating at temperatures of up to 200 degrees Celsius.

Biomolecular Tweezers Facilitate Study of Mechanical Force Effects on Cells and Proteins

March 10, 2014 -- A new type of biomolecular tweezers could help researchers study how mechanical forces affect the biochemical activity of cells and proteins. The devices – too small to see without a microscope – use opposing magnetic and electrophoretic forces to precisely stretch the cells and molecules.

Single Chip Device to Provide Real-Time 3-D Images from Inside the Heart and Blood Vessels

February 18, 2014 -- Researchers have developed the technology for a catheter-based device that would provide forward-looking, real-time, three-dimensional imaging from inside the heart, coronary arteries and peripheral blood vessels. With its volumetric imaging, the new device could better guide surgeons working in the heart.

Silicon-Germanium Chip Sets New Speed Record

February 18, 2014 -- A research collaboration has demonstrated the world's fastest silicon-based device to date. The investigators operated a silicon-germanium (SiGe) transistor at 798 gigahertz (GHz) fMAX, exceeding the previous speed record for silicon-germanium chips by about 200 GHz.
