SAW and BAW devices for harsh environment sensing

Posted by frec|n|sys SASResponsive · Innovative Products and Technologies · France

Summary of the technology

the company proposes battery-less and wireless sensors capable to operate under very harsh environment, particularly high temperature conditions with a target at 1000°C. The company has developed SAW sensors designed to operate above 600°C for which a new solution for sensor/antenna assembly has been developed and protected. frec|n|sys has developed its own patent portfolio and a various temperature sensors now are available in frec|n|sys early catalog.

Description of the technology

The company dedicates a strong R&D effort for the development of battery-less and wireless sensors capable to operate under very harsh environment, particularly high temperature conditions with a target at 1000°C. In that pursuit, the company exploits results based on SAW sensors designed to operate above 500°C (more than 600°C demonstrated, see for instance Figure 2) for which a new solution for sensor/antenna assembly has been developed and protected (result of European project SAWHOT). frec|n|sys also has developed its own patent portfolio on that topic and a first generation of temperature sensors now is available in frec|n|sys early catalog.

The company also is active for the design and fabrication of SAW filters and resonators mainly for Defense and Space applications (see ), with several customers in that domain. frec|n­|sys also is active as a general purpose foundry for specific-high added value technological operation. Finally, frec­|n|­sys offers its customers to accompany them for the development of their activity based on SAW/BAW devices and proposes analysis of IP status in the related development branches.

About frec|n|sys SAS

Small and Medium Enterprise from France

frec|n|sys designs, fabricates and commercializes passive RF components (surface acoustic wave – SAW, bulk acoustic wave – BAW, guided acoustic wave devices in general), i.e. sensors, filters and resonators for on-board signal processing. The main applications of such devices are dedicated to harsh environment monitoring, Defense/Space and Telecoms.

The company was created in early 2013 to answer the national demand and international need for advanced SAW device development and production. The skill and expertise of the company originate from competences developed at the FEMTO-ST Institute/CNRS - Besançon. The company owns a patent port-folio protecting its innovation particularly in the field of sensors for harsh environment for which the company ambition to be an international leader. Since Ocyober 2017, frec|n|sys is a 100% subsidiary of the SOITEC group which develops and commercializes advanced SOI wafers for microelectronics and a novel generation of oriented single-crystal piezoelectric layer on silicon, the so-called POI (piezoelectric-on-insulator) wafers.
