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.

Allahabad HC orders probe into 'reinstatement' of teacher in UP's Barabanki
Lucknow (PTI): The Lucknow Bench of the Allahabad High Court on Friday ordered a probe by the special task force (STF) into alleged irregularities in the rejoining of a teacher at City Intermediate College in Barabanki, observing that the reinstatement appeared to be prima facie illegal.
The court also directed the recovery of the salary paid to the teacher during the disputed period.
A bench of Justice Rajeev Singh passed the order on a petition filed by the college management committee. The court expressed doubts over the roles of the District Inspector of Schools (DIOS), Barabanki, the college principal and the teacher concerned and hence, directed a detailed inquiry into the matter.
Taking note of alleged manipulation of records and misleading submissions, the court ordered the immediate transfer of the Barabanki DIOS to ensure a fair probe. It also directed the initiation of disciplinary proceedings against the then joint director of education of the Ayodhya division.
In its order, the court found that the teacher, Abhay Kumar, was initially appointed as an assistant teacher in 2018 but joined an Eklavya Model Residential School in Chhattisgarh as a lecturer in June 2024 without obtaining permission from the management. His subsequent request to retain the lien was rejected.
Despite this, he was allowed to rejoin the Barabanki College in September 2025 on the directions of the joint director of education and the DIOS, and was even paid the salary for October 2025. The court termed the rejoining "wholly illegal" and lacking any legal basis.
The bench also expressed concern over lapses in communication within the education department and directed the Uttar Pradesh chief secretary to ensure that official orders are communicated through email and WhatsApp as well, to prevent disputes.
The matter is next listed for hearing on May 28 when a compliance report is sought.
