It's great to finally see a use for this technology. But is it the disruptive application that organic electronics has been desparately seeking for the last decade? I am not sure about that.


I am also curious about the day to day usability of this approach. From the looks of it, the label has to be contacted with some kind of springy probe. This may prevent use on non-rigid packages and could lead to damage to the product or the label itself. I also image a non-contact approach, such as RFID or a microgravure hologram may be more convenient, but maybe the price point is a differentiating factor here.

I think Thin Film also has research into RFID tags and NFC but you are right, it is a more expensive solution

Yes you are right contact based technology will not be much proven for multiple accesses and this might become a hindrance in adaptability of it.

Brand Protection?

Interesting that the target application is "brand protection." Seems like a a 4bit mixed analog/digital signature wouldn't be that hard to copy... And would this be used by the "copyright police" as they are scanning incoming products?

Well you would have to know first what the reader is looking for....

then you would have set up a plastic memory manufacturing line....

...part of the signature relates to the ferroelectric plastic composition ....part to the nanometric thickness of the layer and part to the area of the memory cell.

All are varied to produce the signature.

 

It's a lot easier to forge a holographic security tag Sujita told me

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
