About JonDeTech and the product

JonDeTech is a new company that develops the technological platform enabling low cost IR-, heat flux and ΔT sensors to be produced directly in a flexible printed circuitboard. Although it was founded in 2008 the development was started already in 2003 as a collaboration between Uppsala University and SenseAir AB.

The infrared detector is a thermopile giving a direct voltage response when subjected to infrared light or heat. The hot and cold junction corresponds to respective front and back surface of the flex foil. Hence the thermocouple leads/legs are "vertically" arranged.

These thermal radiation detectors could be used e.g. in heat flux or contactless temperature applications without the requirement of special package or assembly (such as metal encapsulation)

Key Features of the Thermopile

1. The thermopile sensor is thin (0.15 mm) and bendable
2. The price is low
3. Produced using a low cost flexible-PCB technique
4. It can measure both thermal radiation and heat flux
5. The thermopiles are typically delivered "IR-chips" that can be surface mounted on commercial PCB carriers. Standard dimensions are 3x3, 5x5 or 7x7 mm chips
6. Sensor arrays can be realized (e.g for position sensors)
7. Specific detectivity in the range of D*=1-5e7 cm√Hz/W
8. Responsivity to irradiance for 5x5 mm sensor area: I_v=20 Vmm²/W
9. Custom made design with e.g. integrated auxiliary circuitry

Information about the sensor development and the prototype is found in the JonDeTech development INFO document (PDF). Technical information can be found in the thermopile datasheet (PDF). Updated information will soon be announced.

Today, our primary goal is to build the first (low volume) production line. During the late autumn we expect to reach a production capacity of 10'000 sensors/year.

July-Dec, 2008. Work is now beeing focused towards building the first real production line. During late autumn we expect a production capacity of 10'000 sensors/year.

June 4-6, 2008. Please visit us at the Shanghai Sensor Exhibition 2008, IACEXPO. We are found in the SenseAir stand. For questions talk to Arvid Egeland.

May 30, 2008. Internal (JonDeTech) discussions in what direction to proceede and what focus to have. We would now like even more feed-back from potentially interested customers. We will produce a questionaire/form soon to be found on this web page. We encourage all interested companies to fill out this.

May 6-8, 2008. We presented our infrared sensor technology at the the SENSOR + TEST 2008 meeting in Nürnberg (Nuremberg). (In the same stand as SenseAir, Hall 9). Our impression was that our visitors was interested in this new technology; we got a lot of positive feed-back. Partly there was a "generic" interest in the new technology platform but also specific interest for use in different applications ranging from companies involved in White goods, consumer electronics, surveillance, medical applications and heat flux sensing.We would like to thank all our visitors for this valuable feed-back.
