Real-time monitoring of garment pressure and strain by integrating FBG sensors into knitted fabric
Annotatsiya
This study examines a novel method for incorporating Fiber Bragg Grating (FBG) sensors directly into knitted fabric during manufacturing, enabling real-time monitoring of pressure and strain. These sensors are great for wearable devices because they are small, do not block electromagnetic signals, and can read multiple sensing points along one fiber. Adding optical fibers to a polyester-elastane knit makes the fabric comfortable and durable, and it also accurately records biomechanical data. Calibration tests showed that changes in strain and wavelength were clearly linked in a straight line. They also showed that the material reacted in a consistent nonlinear way to the kinds of pressures that are common in physiological conditions. We tested the prototype on someone who was walking and squatting, and it did a great job of keeping track of strain cycles with little noise and high sensitivity. The sensor worked mostly the same after being washed many times, which shows how strong the integration method is. Some baseline measurements showed drift because the temperature changed, it was noted. This means that future designs will need to have special ways to deal with temperature changes. This method is better for durability and wearability than older methods that put sensors on the outside. It also doesn't lose its accuracy. The results show that you can make a lot of smart clothes for health care and sports. The next step is to add more wireless sensors and sensing points so that the whole body can be mapped in terms of how it moves.
