Demo Videos

Color LED array video:

  • Wiring does not break when bent or stretched
  • And it returns to its original state.

NFC energy harvesting video:

  • In addition to stretching and shrinking, immersion in water does not cause functional problems.

Production cooperation with Printed Electronics Ltd.
