An ordinary thread sewn into fabric can listen to the body. It feels the chest rising with each breath, a finger bending, and the pulse beating at the wrist. All this — without stiff patches or wires, just as part of your clothing.
The sensor is made from a flexible thread that changes resistance when stretched or pressed. It is woven into fabric in a triangular pattern, like a fine mesh. This pattern catches even subtle movements while saving material — only a little thread is needed.
Such a thread could become the foundation of smart clothing: a T-shirt could track breathing during a run, and a glove could monitor finger movements during rehabilitation after injury. All without uncomfortable devices, just fabric that senses.
The flexible sensor thread is woven into clothing in a triangular pattern, like a fishing net, but for body signals. The denser the triangles, the more accurately it detects movements.
