<\/noscript><\/figure>\n<\/div>\nThe system consists of thin, flexible fibers with a fluid core that can contain either air or a liquid that can be compressed or released to actuate the fibers, thereby making them act like artificial muscle fibers. The flexibility and small profile of the fibers allows them to be sewn or woven into fabrics, and their thin structures contain sensors that can detect how much the fibers stretch during movement. \u00a0\u00a0<\/p>\n
The fibers consist of five layers: a fluid channel, a surrounding silicone layer, a stretchable sensor to monitor stretching during use, a braided polymer mesh, and a non-stretchy filament to prevent overextension.<\/p>\n

When incorporated into garments, the fibers have numerous applications, not all of them medical. For instance, the researchers suggest that they could help singers perfect their breathing technique. An experienced singer could use the device to create an \u2018imprint\u2019 of the correct breathing technique, and then a novice could wear the garment and it would prompt them to activate specific muscles while singing.<\/p>\n
The fibers can respond very quickly, and rapidly provide tactile feedback during use. However, refining respiratory muscle control would also be helpful for those who are experiencing respiratory difficulties because of surgery or the aftermath of a respiratory illness such as COVID-19. Indeed, the garments could be useful for a wide variety of muscle training applications for rehabilitation.<\/p>\n <\/noscript><\/figure>\nIn the next steps, the researchers wish to miniaturize the system that supplies compressed air and the electrical components of the system, while also increasing the potential length of the manufactured fibers. \u201cEverybody has to breathe. Breathing has a major impact on productivity, confidence, and performance,\u201d said Hiroshi Ishii, a researcher involved in the study, via an MIT announcement. \u201cBreathing is important for singing, but also this can help when recovering from surgery or depression. For example, breathing is so important for meditation.\u201d<\/p>\n
