The Textile Generates Electricity When the Fibers Are Deformed (VIDEO)

Chalmers University of Technology

Caption

When the textile is stretched or exposed to pressure, the deformation of the piezoelectric fibers (pink) causes a reorganization 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 fibers as thin as a hair, and each fiber has an electrically conducting core (black).
