A breeding ground for French startups: Page 3 of 5

Taking place from the 6th to the 9th of October in Grenoble's AlpExpo exhibition centre, SEMICON Europa not only packed an impressive number of presentations and forums, ranging from Semiconductor processing and packaging to Plastic Electronics, MEMS manufacturing and test issues, the exhibition also hosted a buoyant “Innovation Village” where French startups pitched their ideas and showcased their product concepts.
Irlynx - www.irlynx.com - hopes to undercut the presence detection market with a very low cost uncooled infrared sensor, built from pyro-electric PolyVinylidene Fluoride (PVDF) as the underlying sensing technology and a cheap polyethylene high-density optic.

Founded in 2013 by Sébastien Fabre, the company has developed several detector arrays ranging from 16×16 pixels to more than 128×128 pixels with a thermal resolution under 1ºC and a customizable working distance (via the optics) to range from 1m to more than 15 meters. 

The horizontal field of view can also be tuned through the choice of the optics, from 30° to more than 120°. Tied to an MCU, the full sensing unit offers various industrial interfaces such as UART, I2C, or SPI, the total solution fitting in less than 1cm3.

“Basically, it is PVDF spin-coated on top of an array of electrodes combined with reading circuitry”, told us Fabre, Irlynx’ CEO, “so it is completely compatible with CMOS manufacturing processes”.

The company also provides a bunch of advanced image processing algorithms to interpret the sensor’s data as presence detection, with the capability to count subjects, track their displacement, set up alarms based on posture or geo-fencing perimeters.

“Our solution is several orders of magnitude cheaper than current infrared monitoring systems, and unlike camera-based solutions, we only distinguish anonymous subjects as rough shapes, hence we preserve people’s privacy”, commented Fabre.

The company had fake samples in hand, looking for the right investors to come up with the finalized goods.
