Piezoelectric Braided Cord
Piezoelectric braided cord is a "string-like" sensor that generate voltage with a pulling, twisting, or rubbing motion. It is so thin and soft that they can be sewn onto fabric. Piezoelectric braided cord is woven from environmentally friendly piezoelectric polymer fiber. This braided cord is flexible and resistant to bending, and its measurement function can measure from minute vibrations to large movements.
