| Tomorrow's degradable electronics Posted: 20 Nov 2014 05:19 AM PST Researchers are developing electronics that disappear to order. When the FM frequencies are removed in Norway in 2017, all old-fashioned radios will become obsolete, leaving the biggest collection of redundant electronics ever seen – a mountain of waste weighing something between 25,000 and 30,000 tons. The same thing is happening with today's mobile telephones, PCs and tablets, all of which are constantly being updated and replaced faster than the blink of an eye. The old devices end up on waste tips, and even though we in the west recover some materials for recycling, this is only a small proportion of the whole. And nor does the future bode well with waste in mind. Technologists' vision of the future is the "Internet of Things". |
| Paper electronics could make health care more accessible Posted: 19 Nov 2014 08:27 AM PST Flexible electronic sensors based on paper -- an inexpensive material -- have the potential to some day cut the price of a wide range of medical tools, from helpful robots to diagnostic tests. Scientists have now developed a fast, low-cost way of making these sensors by directly printing conductive ink on paper. |
| New electron spin secrets revealed Posted: 10 Nov 2014 09:40 AM PST Researchers have demonstrated that it is possible to directly generate an electric current in a magnetic material by rotating its magnetization. The findings reveal a novel link between magnetism and electricity, and may have applications in electronics. The electric current generation demonstrated by the researchers is called charge pumping. |
| First look at atom-thin boundaries Posted: 10 Nov 2014 08:02 AM PST Scientists have made the first direct observations of a one-dimensional boundary separating two different, atom-thin materials, enabling studies of long-theorized phenomena at these interfaces. |
