The textile generates electricity when the fibers are deformed

When the textile is stretched or exposed to pressure, the deformation of the piezoelectric fibres (pink) causes a reorganisation of the charge distribution, thus generating an electrical voltage. The electrically conducting yarn (blue) is required to form a closed circuit. A piezoelectric yarn is made up of 24 fibres as thin as a hair, and each fibre has an electrically conducting core (black).
