PST's temperature sensors are based around a core technology of a printed silicon NTC thermistor – a device whose electrical resistance decreases when it is heated. Being both printable and electronic, the sensors can be fully integrated with Thin Film's memory and with complementary organic circuits.
"The team behind PST has been working with the printed silicon technology over the last decade, and PST Sensors is the leading company in its field," said Christer Karlsson, Thin Film's chief technology officer. "Its printed silicon sensor technology is uniquely easy to manufacture and offers a low-cost point."
Sutija said it was not yet determined who would go into volume manufacturing with products as that depended partly on the final application. "We already have manufacturing partners, such as Inktec in South Korea, and PST has delivered tens of thousands of printed systems. We have the means of scaling manufacturing. Each market will have its own constraints."
"Relationships with complementary technology partners are a key part of our roadmap to support the Internet of Things where objects can collect and communicate data, with people and with each other," Sutija added. "Acreo's printed electrochromic displays are ideal for our display requirements in segmented displays, such as alphanumeric characters and battery meters. The display's low price - a few cents per display – and low power makes Acreo's display technology an excellent addition to our technology portfolio."
"In addition, we will be working with Imprint Energy to develop and test samples for low-power, ultra-high volume applications like temperature tags and small-scale displays. Imprint’s technology requires very little packaging, making it cost effective to scale the battery to the requirements of a given application. We are pleased to work with both companies," added Sutija.
Imprint Energy is commercializing a flexible, rechargeable battery technology developed by founders from the University of California, Berkeley. Imprint Energy’s polymer electrolyte technology is not lithium based and enables print-based manufacturing of energy dense and ultra-thin batteries based on abundant materials, Thin Film said.
The first demonstration prototype of printed sensor system is expected to be completed in the second half of 2012.
I can tell that the partnership between the few companies would be good because they would be collaborating in a way that brings out the best in their collective expertise. I think we can look forward to interesting new functions for plastic films, such as plastic films that can tell us the expiry of foods.

These low cost monitoring solutions will certainly attract attention - but how compatible are they with food? Can the battery and circuit be cut with a knife and safely ingested with the food? If not, how will the packaging be designed to ensure that the monitor is removed before the food is prepared?
