Electric Textile Lights a Lamp When Stretched (VIDEO)

Chalmers University of Technology

Caption

Anja Lund demonstrates the technology with a piece of the electric textile in the shoulder strap of a bag (the lighter-colored part). When the textile is stretched it builds up voltage in a capacitor until the voltage is high enough to intermittently power a connected LED. If the entire bag were made from the electric textile it could generate sufficient voltage to e.g. power an LED continuously.
