Key Takeaways
- Researchers in China developed a flexible fiber that acts as a full computer, integrating multiple functions into one thread.
- The fiber includes advanced features like sensors for temperature, motion, and blood flow, along with a microcontroller and communication capabilities.
- It can bend up to 60% without damage, thanks to coiled copper microwires.
- Clothing made with these fibers can accurately detect exercises, achieving up to 95% accuracy with multiple strands.
- The innovation has potential for health monitoring and motion tracking in apparel, but challenges remain in power supply, bandwidth, and mass production.
Researchers in China have introduced a flexible fiber that can be washed in machines and acts as a full computer, integrating sensors, processing capabilities, storage, and communication into one single thread.
Advanced Features
This fiber computer stands out from earlier "smart textiles" that merely integrated basic conductors. It incorporates a microcontroller, sensors for temperature and motion, a photodetector, and a photoplethysmogram sensor that keeps track of blood flow. The design features coiled copper microwires that allow the system to bend up to 60% without damage, while integrated modules manage both optical communication and Bluetooth.
Impressive Performance
Initial experiments showed that clothing made with these fibers could detect exercises like squats and lunges. A lone strand achieved roughly 67% accuracy, whereas four strands working together reached about 95%, demonstrating the advantages of connected sensing.
The idea has the potential to create apparel that serves as a health monitor or motion tracker, eliminating the need for bulky devices. While there are still obstacles such as power supply, bandwidth, and mass production, the team has demonstrated that future computers could be woven right into your clothing, rather than just being carried in your pocket.
