Working with Leti's silicon, optics and photonics divisions, the two organizations expect to create a technology that will enable pyroelectric detector arrays to count people, distinguish humans and location and determine posture. The collaboration is based on the development of specific microelectronic steps above a conventional CMOS IC and on the hosting of Irlynx R&D's activities inside Leti's clean-room facilities.
Leti will provide the partnership with its expertise in advanced materials and photonics technologies while Irlynx focuses on IC design, optic integration and "on-die" data processing.
The sensor is based on CMOS-compatible proprietary uncooled thermal sensing technology made using the pyroelectric properties of polyvinylidene fluoride (PVDF). The company plans to create arrays from 16 by 16 up to more than 128 by 128 pixels formed above a CMOS wafer where the on-die processing is done. The technology has a thermal resolution of less than 1 degree C and a range of up to 15 meters or depending on the optics, the company claims. Irlynx hopes to find applications in energy saving and building management, security, assisted living and more general interactive objects.
The company was founded in 2012 by Sebastien Fabre. Fabre previously worked as a product manager for CMOS and MEMS sensors at NXP Semiconductors and Tronics. The company has received €1 million (about $1.3 million) in funding.
