Scientists develop clothing that can communicate
New York, Aug 12 : Researchers have, for the first time, produced fibres with embedded electronics that are so flexible they can be woven into soft washable fabrics and made into wearable clothing.
Embedding high speed optoelectronic semiconductor devices, including light-emitting diodes (LEDs) and diode photodetectors, into washable fabrics also makes it possible to produce clothing that communicates optically with other devices.
This discovery, described in the journal Nature, could unleash a new 'Moore's Law' for fibres, in other words, a rapid progression in which the capabilities of fibres would grow rapidly and exponentially over time, said researchers from the Massachusetts Institute of Technology (MIT) in Boston.
The key breakthrough for producing these new fibres was to add to the preform light-emitting semiconductor diodes the size of a grain of sand, and a pair of copper wires a fraction of a hair's width.
When heated in a furnace during the fibre-drawing process, the polymer preform partially liquifies, forming a long fibre with the diodes lined up along its centre and connected by the copper wires.
"We are anticipating the emergence of a 'Moore's law' analogue in fibres in the years ahead," said Yoel Fink from the varsity.
"It is already allowing us to expand the fundamental capabilities of fabrics to encompass communications, lighting, physiological monitoring, and more. In the years ahead, fabrics will deliver value-added services and will no longer just be selected for aesthetics and comfort," Fink added.
In this case, the solid components were two types of electrical diodes made using standard microchip technology: LEDs and photosensing diodes.
The resulting fibres were then woven into fabrics, which were laundered 10 times to demonstrate their practicality as possible material for clothing.
One of the advantages of incorporating function into the fibre material itself is that the resulting fibre is inherently waterproof.
To demonstrate this, the team placed some of the photodetecting fibres inside a fish tank.
A lamp outside the aquarium transmitted music through the water to the fibres in the form of rapid optical signals.
The fibres in the tank converted the light pulses -- so rapid that the light appears steady to the naked eye -- to electrical signals, which were then converted into music. The fibres survived in the water for weeks.

Modi should leverage his ties with world leaders to de-escalate war in West Asia: Omar Abdullah
Jammu (PTI): Jammu and Kashmir Chief Minister Omar Abdullah on Monday said India can play a meaningful role in de-escalation in West Asia, given Prime Minister Narendra Modi's strong relations with the warring countries and their neighbours.
He said Pakistan was leveraging ties with Iran and the United States, and that any effort towards ending the war should be welcomed.
"As I said in the House (Assembly), we would like the war to end as soon as possible. The role that the prime minister can play may not be possible for anyone else because of his good relations with all these countries," Abdullah told reporters on the sidelines of a function here.
He, however, said any escalation would not be easy to manage.
"Any such move by US President Donald Trump, despite the long history of Iran resisting external domination, would not be easy," the chief minister said.
Asked about Pakistan mediating in the war, he said, "I will simply say that if any country can play a role in preventing this war, no one should have any objection to it."
He added, "I will repeat what I said … our prime minister has good and close relations with all countries — whether it is Israel, the United States, Iran, or the countries around Iran. If those relationships can be used to make some progress and help ease the situation, it would be a good thing."
Abdullah said attacks by terror groups like Lashkar-e-Taiba and Jaish-e-Mohammed in India, as suggested by a report from the United States, are not unlikely.
Meanwhile, he asserted that any efforts to end the war, be it from Pakistan, must not be resisted.
"Pakistan is using its good relations with Iran and the United States to its advantage, and it has done so. How can we object to that? If that angle helps in stopping the war, would you want them not to act and let the war continue? We want the war to stop. If any country can play a role in that, it should. And if we can play an even better role, then we should do so," he said.
On unemployment in J-K, the chief minister said the issue cannot be resolved overnight, and government jobs alone are not the solution.
He stressed the need to explore alternative avenues, highlighting the importance of Mission Yuva in promoting entrepreneurship.
"Mission Yuva provides not just funding but also support in preparing DPRs and post-startup assistance, such as marketing. In just nine months, distributing Rs 1,000 crore and approving numerous schemes is a significant achievement," he said.
Abdullah credited the coordination between the government and Jammu and Kashmir Bank for the scheme's progress.
