 3D printing of superfine electronic fiber, which can monitor breathing

The infinite potential of wearable devices makes it the direction of scientific research.

Recently, researchers at Cambridge University have developed electronic fibers using 3D printing technology. Each fiber is 100 times thicker than human hair. The sensors made from electronic fibers are beyond the capabilities of traditional thin-film devices.

The fiber printing technology could be used to make contactless, wearable portable breathing sensors, according to the journal scientific progress. These printed sensors have high sensitivity and low cost, and can be installed on the mobile phone to collect respiratory mode information, sound and image at the same time.

In the study, the researchers turned the fiber sensor into a portable breathing monitor, applied it to masks, and then used it to monitor subjects breathing. Using the sensor, the team not only successfully detected signs of shortness of breath, shortness of breath and simulated cough, but also sensitively tracked the location of air leakage in the subjects mask.

In addition to respiratory sensors, the researchers say printing technology can also be used to make biocompatible fibers of similar size to biological cells, enabling them to guide cells to move and feel the dynamic process in the form of electrical signals. In addition, these fibers are so tiny that they are invisible to the naked eye, so when they are used to connect small electronics in 3D, they seem to float in mid air.

The team hopes to develop the fiber printing technology for a variety of multi-functional sensors, which may detect more respiratory species for mobile health monitoring or biomedical machine interface applications, which will also bring more possibilities for wearable devices.
