We developed an organic semiconductor based strain sensor
sheet for an input system on flexible OLEDs. As resistors
for strain gauges, we used a conductive polymer of poly (3,
4 - ethylenedioxythiophene) (PEDOT):polystyrenesulfonate
(PSS) which is useful for touch input devices. This is
because PEDOT: PSS has the advantages of flexibility and
transparency. The strain sensor array was fabricated with
the Parylene peel-off process. The resistance change of the
fabricated PEDOT-based sensor was measured on diverse
radii of curved surfaces. Finally, we demonstrated the
capability to accept input by touching the sensor sheet both
on flat and curved surfaces.
