electronics miniaturization heads towards a theoretical physical limit in the
tens of nanometers, new methods of manufacturing are required to produce
transistors, diodes, and other fundamental electronic components. In this vein, a new range of molecule-sized
devices have been created in the laboratory, though with varying results in
terms of efficiency and practicality. Now a group of researchers from Berkeley
Lab and Columbia University claims to have created the highest-performing,
single-molecule diode ever made, which is said to be 50 times better in
performance and efficiency than anything previously produced.
Sydney, Australia, has become the world's first city to boast E Ink-based traffic signs. Built by RMS and integrating Visionect’s e-paper signage electronics and software, the solar-powered signs promise both greater efficiency and improved reliability compared to than standard electronic roadsigns.
3D printers are fantastic, but you're unlikely to see someone carrying one with them to a maker faire, or anywhere else for that matter. Elecfreaks is aiming to provide a portable option for the growing 3D printer market with Freaks3D – a unit that's around the size of an average laptop.
Most Instagram users probably check their feed with a smartphone or
similar device. New York-based studio Breakfast, however, has created a
machine that displays Instagram images and basic animations using
thousands of spools of thread.
No matter how many new forms of technology we come up with for writing,
pen and paper always seems to have a place. It's with this in mind that
smart pens like LiveScribe and the Neo Smartpen N2
have come into use. Now, a new device called Paper4Everyone aims to
take the idea of a connected pen a step further by adding in a
Researchers from Germany, Japan and the United States have managed to create a tiny, reliable transistor assembled from a single molecule and a dozen additional atoms. The transistor reportedly operates so precisely that it can control the flow of single electrons, paving the way for the next generation of nanomaterials and miniaturized electronics.
An Enigma machine, used by Germany to send encrpted communications during World War II, has been sold at auction in London. The machine, which was constructed in 1943, is one of few that survived the conflict intact, as the German military was given orders to destroy the machines as it retreated.
IBM Research has successfully created the first 7nm node test chip with functioning transistors, a development that could lead to processors that boast four times the capacity of those on the market today.
Researchers at MIT have developed a new type of flexible, nanowire-based
supercapacitor with performance vastly exceeding its graphene
counterpart. It could find use as the ideal energy source for the next
generation of fitness trackers and other wearable devices.
Scientists at the Korea Advanced Institute of Science and Technology (KAIST) have developed an omnidirectional wireless charging technology that can charge multiple devices at once, at a distance and, crucially, at peak efficiency regardless of which way the devices are facing. The technology, said to be safe for humans, is set to be trialled in cafes and offices and could allow for much more convenient charging of mobile devices.
