What are E-Textiles? Electronic textiles (e-textiles) are fabrics that have electronics and interconnections woven into them, with physical flexibility and size that cannot be achieved with existing electronic manufacturing techniques.
Components and interconnections are intrinsic to the fabric and thus are less visible and not susceptible to becoming tangled together or snagged by the surroundings. An e-textile can be worn in everyday situations where currently available wearable computers would hinder the user.

Graphene windows' clearer focus. 8 April 2012Last updated at 03:44 ET Pockets formed in the graphene sheets allowed the team to study liquids at higher resolution The carbon-based material graphene can help scientists study liquids more clearly with high-power microscopes. Details of the advance are reported in Science journal. Graphene can form a clear "window" to see liquids at higher resolution than was previously possible using transmission electron microscopes.
Liquids had been difficult to view at the same resolution as solids because these microscopes require the liquids to be encapsulated by some material. Traditionally, silicon nitride or silicon oxide capsules, or liquid cells, have been used. Now, Jong Min Yuk at the University of California, Berkeley, and colleagues have shown that pockets created by sheets of graphene can be used to study liquids at clear, atomic, resolution using transmission electron microscopes (TEMs). They noted how the crystals selectively coalesced and modified their shape. Graphene. Secrets of the first practical artificial leaf. A detailed description of development of the first practical artificial leaf -- a milestone in the drive for sustainable energy that mimics the process, photosynthesis, that green plants use to convert water and sunlight into energy -- appears in the ACS journal Accounts of Chemical Research. The article notes that unlike earlier devices, which used costly ingredients, the new device is made from inexpensive materials and employs low-cost engineering and manufacturing processes.
Daniel G. Nocera points out that the artificial leaf responds to the vision of a famous Italian chemist who, in 1912, predicted that scientists one day would uncover the "guarded secret of plants. " The most important of those, Nocera says, is the process that splits water into hydrogen and oxygen. The artificial leaf has a sunlight collector sandwiched between two films that generate oxygen and hydrogen gas.

Find out about the top 10 emerging technologies for 2014 here. New challenges need new technologies to tackle them.
Here, the World Economic Forum’s Global Agenda Council on Emerging Technologies identifies the top 10 most promising technology trends that can help to deliver sustainable growth in decades to come as global population and material demands on the environment continue to grow rapidly. These are technologies that the Council considers have made development breakthroughs and are nearing large-scale deployment. OnLine Electric Vehicles (OLEV) Wireless technology can now deliver electric power to moving vehicles. In next-generation electric cars, pick-up coil sets under the vehicle floor receive power remotely via an electromagnetic field broadcast from cables installed under the road.
The current also charges an onboard battery used to power the vehicle when it is out of range. 3-D printing and remote manufacturing Self-healing materials Energy-efficient water purification.
