Introduction benefits

The PEDOT transparent touch sensor benefits from the transparent soldermask of the single-sided flexible PCB P-Flex® PET and can be made in any shape or design. The sensor is suitable for applications such as capacitive switches where thinness and design are important.

  • Can be attached to curved surfaces thanks to its flexibility
  • Uses transparent soldermask allowing for permeability in all but the wiring (additional fees apply)
  • Can be installed without compromising the design of the casing
  • Flexible light-transmitting capacitive sensors can be made by mounting LEDs
  • Replaces physical switches
  • Also compatible with proximity sensors

Electrical performance(depends on circuit specification)

・Surface resistance: 200Ω/sq (typical value)


Environmental performance(depends on circuit specification)

・High temperature test: no variation of more than ±50% from the initial resistance and no abnormality in appearance after 250 hours at 105˚C.

・ Low temperature test: no variation of more than ±50% from the initial resistance and no abnormality in appearance after 250 hours at -40˚C.

・Thermal shock test: no abnormalities in appearance or resistance after 100 cycles of spending 30 minutes at -65˚C and 30 minutes at +125˚C
