Printed organic sensor company ISORG demos its first product in these Youtube videos:
This bar graph applet illustrates what the ISORG organic sensors "sees" on top of the tablet, it estimates a relative distance to the object on top the pad by the amount of light each pixel receives:

Thanks to SG for the link!
Update: Here is Photonics 21, Sept. 2011 presentation by ISORG.
is a simple photodiode array enough for this application?
ReplyDeletethe problem with a simple photodiode array would be the pixel pitch that would be package dependent and the assembly cost.
ReplyDeleteISORG technology enables to print (ink jet type of printings) a complete array of photo diode at a defined pitch on a plastic substrate, that can be conformable and/or flexible. thus enabling low cost and better integration.
