MIT creates smart textiles that capture human movements
Specialists at the Massachusetts Institute of Technology (USA) have created a woven material that can be used in smart clothes. This is reported on website organizations.
The engineered 3DKnITS material adheres tightly to the body to precisely capture the movement and posture of a person. MIT researchers used several pressure sensors woven into multi-layered knitted fabrics. The resulting textiles can be used in the production of smart clothes.
To produce the smart fabric, the researchers used a digital knitting machine that weaves layers of fabric with rows of standard and functional yarns. The multilayer knitted fabric consists of two layers of conductive knitted fabric sandwiched around a piezoresistive material that changes its resistance when compressed. Then the information collected by 96 sensors is interpreted by the neural network.
After the scientists trained the model, artificial intelligence was able to determine the user’s movements. The authors reported that the accuracy of the analysis of exercise performance was 99.6 percent. According to experts, the fabric they developed can be used to create smart clothing used in rehabilitation medicine and sports.
At the beginning of 2022, American scientists created a prototype of a flexible thermometer that can be used in smart clothes. The new thermometer can measure temperatures ranging from 200 to minus 100 degrees Celsius.
