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.

Woman's death: Under fire Pune-based Deenanath Mangeshkar Hospital announces 'no deposit' policy
Pune (PTI) The Deenanath Mangeshkar Hospital in Maharashtra's Pune city, under fire for allegedly turning away a pregnant woman over non-payment of Rs 10 lakh as advance for treatment, on Saturday announced it would no longer be taking deposits from patients at the emergency department.
The woman, wife of the personal secretary of BJP MLC Amit Gorkhe, had to be shifted to another hospital where she died after delivering twins. The incident hit national headlines and evoked strong condemnation from leaders cutting across party lines as well as protests from citizens' groups.
In an open letter, the hospital's medical director Dr Dhananjay Kelkar said, "In the early years of Deenanath Mangeshkar Hospital, we never took a deposit. But as the number of critical cases increased and the cost of complex treatments rose, the hospital began taking deposits in certain high-cost cases."
"However, in light of yesterday's events, we have re-evaluated this practice and passed a resolution that the hospital will no longer take any deposit from patients entering through the Emergency Department, including emergency deliveries and paediatric emergencies. This will be implemented with immediate effect," Dr Kelkar said in the letter.

He defended the hospital by reiterating that he had personally told the woman's kin to pay as per their ability and also offered all help, but they left with the patient without informing anyone.
While it is factually incorrect and unfair to hold the hospital directly responsible for the incident and the unfortunate death, the hospital is still investigating whether it showed adequate sensitivity towards the patient, Dr Kelkar added.
"I had myself told the woman's relatives to pay whatever amount they could as a deposit and assured them of complete support. However, they left the hospital with the patient without informing anyone," he stated.
Alluding to the protests at the hospital by various political parties on Friday, Dr Kelkar termed it as a "black day".
Without any regard for the hospital's legacy and services, a group participating in the morcha (protest) threw coins at the public relations officer, while some women activists allegedly barged into a hospital run by the parents of Dr. Sushrut Ghaisas and vandalized it.
Dr Ghaisas has been accused by the kin of the deceased woman seeking the deposit ahead of admission.
"Our heads hung in shame when some protestors blackened the names of Lata Mangeshkar and Deenanath Mangeshkar, all of this taking place in front of media cameras," Dr Kelkar said.
An internal inquiry report of the Mangeshkar Hospital had claimed on Friday that the allegations of denial of admission for non-payment of Rs 10 lakh were "misleading" and made "out of frustration" by her family.
The woman's pregnancy was in the high-risk category, and her two underweight foetuses of seven months, coupled with a history of an old ailment, required Neonatal Intensive Care Unit (NICU) treatment for at least two months, it said.
The treatment required Rs 10 lakh to Rs 20 lakh and the family was advised that in case of lack of funds, they could admit the patient to the government-run Sassoon General Hospital for a complicated surgery, it added.
Maharashtra Chief Minister Devendra Fadnavis has announced the formation of an inquiry panel under the Pune-based Joint Commissioner of Charity to look into the incident.
