The Fiber Computer: A Technological Marvel

The fiber computer is an autonomous programmable device in the form of an elastic fiber. It contains a series of microdevices, including sensors, a microcontroller, digital memory, Bluetooth modules, optical communications, and a battery – essentially all the components of a computer in a single thread 2

This innovative technology offers several advantages over traditional wearables:

1. Extensive body coverage: Unlike single-point wearables, fiber computers can be in contact with large areas of the body.
2. Comfort and practicality: The fibers are nearly imperceptible to the wearer and the resulting clothing is machine-washable.
3. Flexibility: The fiber can stretch more than 60% without failure.

Applications and Potential

The primary application of this technology is in health monitoring and activity tracking. In experiments, researchers integrated four fiber computers into a top and leggings, running along each limb. The system demonstrated an impressive ability to recognize exercises performed by the wearer 1
