3D printed fibers can detect leakage in your protective mask

A research group at the University of Cambridge has 3D printed electronic fibers capable of monitoring health and detecting possible leaks in the masks. How does it work? The tiny transparent conductive devices act as sensors to capture breath, sound, and biological cells. Communicated through the journal Science Advance, this project is especially useful for health monitoring and biosensitivity applications, especially in the context that we currently live in.

Due to the health crisis caused by COVID-19, many 3D printing companies stepped up to manufacture protective gear. In the last months we have seen how technology developed respirators, swabs for virus testing, and other equipment for the healthcare sector. In addition, the use of masks has become the “new normal” in society. However, it is important to pay attention to the quality of these masks to avoid further spread of the virus.

3D printed fibers to ensure better protection

In this context, the research team from Cambridge began to develop this project to find the leaks in masks. From capturing the breath to guiding the biological movements of the cells, the 3D printed fibers are able to “smell, hear and touch”. The researchers opted for 3D printing with silver and semiconductor polymers for the production of the conductive fiber core. Found in a thin polymer sheath, the core resembles a classic electrical wiring, although with a diameter of a few micro centimeters.
