Researchers have created the first fiber with memory, chips, sensors and a neural network, which is capable of working with digital data.

Until now, all electronic textiles were analog, that is, it was transferred to an electrical signal, and not digital. Now the team of engineers from the Massachusetts Institute of Technology has developed flexible polymer fiber with a continuous electrical connection of hundreds of silicon microchips for tens of meters.

The resulting thread is so subtle that it can be passed through the needle ear, to sew even to wash more than 10 times without damage. Digital fiber can also store a large amount of information in memory. Researchers were able to record, store and read the fiber data, including a 767-kilobite full-color short video file and a 0.48-megabyte music file. Files can be stored for two months without meals.

The command also created a neural network of 1650 connections in textiles. Seviving a fiber to the armpit shirt, the researchers used it to collect data on the surface temperature of a person’s body, wearing a shirt for 270 minutes and analyzing their ratio with various physical exertion. Trained on this data, fiberally able to determine with an accuracy of 96% than the person who brings him.

Such a possibility will further use the technology to detect and prevent people in real time about health changes, such as reducing the frequency of respiration or irregular heartbeat, or transfer data on muscle activation and heart rate athletes during training.

An existing fiber sample is controlled by a small external device, but the command is already working on a microcontroller that can be connected to textiles.
