Stakes

The detection and objectification of odors is a major challenge in various fields such as food safety or automotive. In this context, Aryballe has developed an olfaction technology that enables the recording and objectification of odors. Miniaturization and parallel manufacturing are essential steps for the low-cost industrialization required for mass markets, and may be achieved using silicon technologies.
Mach-Zehnder Interferometer (MZI) and capacitive micromachined ultrasonic transducers (CMUT) are two technologies mastered by CEA-LETI that are promising for the future developments of electronic nose. In the Silinose project, CEA-LETI is devoted to improve its technologies to pave the way for industrialization.

OBJECTIVES

​The Silinose project aims to establish an industrial sector capable of producing high-quality, low-cost sensors that objectively identify odors through digital olfaction.
The project has several ambitions: ​
  • To build a chemical, biological, and fluidic packaging functionalization process at the silicon wafer scale that can be industrialized and transferred.
  • To involve partners from surface treatment and electronics sectors.
  • To develop a demonstrator that integrates and parallelizes all processes to improve the quality and consistency of the sensors while reducing production costs, enabling entry into the automotive market.
IMPACT

The role of CEA-LETI has been :
  • To pursue the development of CMUT technology. Although CMUT present very promising features to be incorporated in electronic noses, they face some challenges among which the need for a scalable technology to adress numerous elements in parallel. CEA-LETI has developped a specific technology to address the electrical contacts from the back side of the silicon wafer, using bulk silicon as a material for electric vias.
  • To improve the performances of Mach-Zehnder Interferometer (MZI) by reducing the optical losses in silicon dioxyde material, by using either Ion Beam Deposition (IBD) or Atomic Layer Deposition (ALD).
  • To develop a functionnalization method to ease the grafting of Aryballe’s peptides, at the heart of Aryballe’s innovations, on silicon-based devices such as CMUT or MZI. ​
