Organic Electronic Interface Devices: Light- and Touch-Point Localization using Flexible Large Area Organic Photodiodes and Elastomer Waveguides (Adv. Mater. 34/2009)



original image

The inside cover shows a flexible, large-area, position-sensitive organic photodetector used as an input device for a desktop computer. R. Koeppe et al. show the assembly of such a device with a photodiode based on a blend of Zn-phthalocyanine and C60 with low conductivity electrodes on p. 3510. The current drop across the electrodes easily allows for the calculation of the position of a localized light signal impinging on the position-sensitive photodetector. By adding an additional elastomer layer with embedded LEDs, the device can also be used as flexible touchpad.
