Abstract :
In the context of novel large-area sensor applications a cost-effective organic thin-film-technology capable of the detection of small changes in ambient temperature has been developed. The technology is based upon ferroelectric fluorinated polymers on the one hand and low-voltage organic thin film transistors on the other hand.
