Áo mới MIT

-----

A new kind of fiber (sợi) developed by researchers at MIT and in Sweden can be made into clothing that senses how much it is being stretched (căng) or compressed (ép, nén, đè), and
then provides immediate (ngay lập tức) tactile (xúc giác) feedback in the form of pressure, lateral (ở bên) stretch, or vibration (rung). Such fabrics (sợi), the team suggests, could be used in garments (quần áo) that help train singers (ca sĩ) or athletes (vận động viên) to better control their breathing (hơi thở, nhịp thở), or that help patients (bệnh nhân) recovering from disease or surgery (phẫu thuật) to recover their breathing patterns.

The multilayered fibers contain a fluid channel in the center, which can be activated by a fluidic system. This system controls the fibers’ geometry (hình học) by pressurizing and releasing a fluid medium, such as compressed air or water, into the channel, allowing the fiber to act as an artificial muscle. The fibers also contain stretchable sensors that can detect and measure the degree of stretching of the fibers. The resulting composite fibers are thin and flexible enough to be sewn, woven, or knitted using standard commercial machines.
