Organic transistor with metal oxide gate dielectric

In early 2011, researchers from the Georgia Institute of Technology described a new method of combining top-gate organic field-effect transistors with a bilayer gate insulator, one layer being inorganic.

Epitaxial graphene shows promise for replacing silicon in electronics

Move over silicon. There's a new electronic material in town, and it goes fast.

Energy harvesting nanogenerators grow stronger

While even the current nanogenerator output remains below the level required for such devices as iPods or cardiac pacemakers, Wang believes those levels will be reached within three to five years.

Broad Scope of Energy Harvesting Event

Energy harvesting is the conversion of ambient energy to electricity in order to power small or mobile devices. It is part of the green revolution in reducing the need for batteries, whether by harnessing heat, light, movement or other things. The unique event "Energy Harvesting USA " will look at this with an unusually broad lens, from the needs of soldiers, building controls, logistics, the process industry and satellites to rotorcraft.

Solvay invests in Polyera to expand printed electronics development

Solvay is investing 4 million USD in a minority stake in Polyera Corporation, a materials developer for the printed electronics market.

Scientists strive to replace silicon with graphene on nanocircuity

Scientists have made a breakthrough toward creating nanocircuitry on graphene, widely regarded as the most promising candidate to replace silicon as the building block of transistors.

Self-powered nanosensors

By combining a new generation of piezoelectric nanogenerators with two types of nanowire sensors, researchers have created what are believed to be the first self-powered nanometer-scale sensing devices that draw power from the conversion of mechanical energy.

Reducing the weight of military manpacks with energy harvesting

The US Army has presented at IDTechEx conferences, pointing out that a US warfighter often has to carry more than the ancient Roman soldier. This is despite the fact that the ancient Roman soldier carried prefabricated fort parts and food, with no support staff. A major problem today is the batteries.

Energy harvesting fabrics

Scientists are researching the development of energy-scavenging fabrics, with in-built nanotechnology which uses the kinetic energy from the wearer's movements and converts it into electricity for powering electronics.

Nanostructures on optical fiber produce hidden photovoltaic cells

Converting sunlight to electricity might no longer mean large panels of photovoltaic cells atop flat surfaces like roofs. uniUsing zinc oxide nanostructures grown on optical fibers and coated with dye-sensitized solar cell materials, researchers at the Georgia Institute of Technology have developed a new type of three-dimensional photovoltaic system. The approach could allow PV systems to be hidden from view and located away from traditional locations such as rooftops.

Electricity produced through muscle movement

Researchers have demonstrated that a hamster wearing a jacket onto which nanogenerators are attached can produce electricity as the animal runs on its wheel.

Flexible charge pump offers another means of producing electricity

Researchers have developed a new type of small-scale electric power generator able to produce alternating current through the cyclical stretching and releasing of zinc oxide wires encapsulated in a flexible plastic substrate with two ends bonded.

Energy harvesting

Energy harvesting, otherwise known as energy scavenging is needed to boost and eventually replace the batteries in printed and other low cost and miniature electronics, particularly in order to extend their life in use.

E coli sensors using silk

Researchers at Georgia Tech in Atlanta, have made electronic biosensors that identify bacteria in poultry plants.

Graphene - highest mobility and processable

Chemists and physicists are hard at work developing production processes for graphene - one day it may even be printable.

"Power shirt" would harvest energy from physical movement

Nanotechnology researchers are developing the perfect complement to the power tie: a

Carbon 60 transistors perform at higher levels than amorphous silicon

Using room-temperature processing, researchers at the Georgia Institute of Technology have fabricated high-performance field effect transistors with thin films of Carbon 60, also known as fullerene.

RFID Copying Nature

Biomimetics is the mimicking of nature to create manufactured products. In RFID it is not new but there is much more to come and nature has lessons for those going in the wrong direction.
