A team from the United States and Sweden is developing fibers to make garments that regulate breathing.

Researchers at the Massachusetts Institute of Technology (MIT) in the United States, MIT Media Lab at Uppsala University in Sweden, and KTH Royal Institute of Technology in Sweden have developed new fibers that can be used in apparel to detect the amount of stretching and contraction. Did. The fibers provide instant tactile feedback in the form of pressure, lateral elongation, or vibration.

According to a MIT news release, such fabrics can be used to train singers and athletes to better control their breathing, and to help patients who have recovered from illness or surgery recover their breathing patterns. The team suggests it can be used.

Multilayer fibers called OmniFibres contain a fluid channel in the center. It can be activated by a fluid system that controls the shape of the fibers by pressurizing and releasing a fluid medium such as compressed air or water into the channel. A fiber that functions as an artificial muscle.

Researchers at the Massachusetts Institute of Technology in the United States, the MIT Media Lab at Uppsala University in Sweden, and the Royal Institute of Technology at KTH in Sweden have developed fibers that can be used in apparel to detect the amount of stretching and contraction. It provides instant tactile feedback in the form of pressure, lateral stretch, or vibration.

The fiber also includes a stretch sensor that can detect and measure the degree of elongation. The resulting composite fibers are thin and flexible enough to be sewn, woven, or knitted using standard commercial machines.

The study, a paper by MIT’s visiting PhD student and research affiliate Ozgun Kilic Afsar, was recently presented at the Association for Computing Machinery’s User Interface Software and Technology Online Conference. Hiroshi Ishii, Professor of Media Arts and Sciences, Jerome B. Wiesner. 8 others from MIT Media Lab, Uppsala University, KTH Royal Institute of Technology in Sweden.

The new fiber architecture has several important features. Due to its very small size and the use of inexpensive materials, it is relatively easy to structure the fibers into a variety of fabrics. The outer layer uses the same material as general polyester, so it is suitable for human skin.

And its fast response time and the strength and versatility it can provide enable a rapid feedback system for tactile training or remote communication (based on tactile sensation).

According to Afsar, the drawbacks of most existing artificial muscle fibers are that they can cause overheating when they are thermally activated and come into contact with human skin, they are power inefficient, or the training process is difficult. .. She says these systems often have slow response and recovery times, limiting their immediate use in applications that require quick feedback.

As the first test application of the material, the team created a type of underwear that the singer could wear to monitor and reproduce the movements of the respiratory muscles and later provide kinesthetic feedback through the same garment, optimal for the purpose. Vocal performance that promoted posture and breathing patterns.

This first test is in the context of audio education, but using the same approach, certain situations based on monitoring a skilled athlete as the athlete performs different activities and stimulates muscle groups. Can help you learn the best way to control your breathing. That’s running, says Afsar.

Ultimately, such clothing is used to help patients regain a healthy breathing pattern after major surgery or respiratory illness such as COVID-19, or even as an alternative treatment for sleep aspiration. It is expected that we can do it.

Afsar will continue to develop manufacturing systems that will allow the entire system, including control electronics and compressed air supply, to be further miniaturized and unobtrusive to produce longer filaments.

This study was supported by the Swedish Strategic Research Foundation.
