Sensors’ integration

List institute integrates all type of sensors by associating in a coherent way transducers, converters, calculation and storage structures and signal processing all together. The whole integrated system can become an electronic card or an integrated component and made completely tolerant to radiative environments and high temperatures.

Our researchers collaborate with industrial companies from aeronautics, railway, automotive and energy sectors. Among their field of expertise we find: image sensors and cable and broadband networks surveillance and diagnosis.

Among our academic partners

INRIA, LGEP-SupElec, Fraunhofer institutes

Assets

  • Coherent and integrated approach for the system’s global optimisation
  • R&D process and technologies destined to all kind of industrial applications

Major technologies

Sensors for thin current sensing

Description

We have developed a System in Package component – SiP - made of a GMR 16 cells array (Giant Magneto Resistance current sensors) for a high precision level of tension measurement including high integration constraints – compact and galvanic isolation – combined with electronics coupled to the transducers and the associated treatment chain. This component is interfaced with a multiplexing card monitored by a digitalisation card connected to a personal computer - PC -. The system has been validated on a vehicle’s fuel cell.
The research focuses on widening measurement possibilities: shorter time cycles, higher power ranges, current and charge loss measurement…

Applications

Batteries, fuel cells, smart metering and smart grids

 

 

Tools for components reliability: applied to hardened cameras for highly radiative environments

Description

In which concerns activities in radioactive environment hardened cameras are a precious tool to operators. Several compact and light hardened cameras have been developed for highly radioactive environments use. Based on market’s standard electronic components the hardening is obtained both by an architectural approach and by the integration of regeneration embedded mechanisms in order to counter radiations deleterious effects. The TID levels are high : 10 000 Gy for a camera used in a contaminated cold zone, 1 MGy for a camera destined to nuclear sites hot zones. For the record, a 10 Gy dose is lethal.

Applications

Hot or contaminated zones inspection, post-accident intervention, dismantling, nuclear facilities process monitoring and surveillance.

Cable networks surveillance and diagnosis

Description

List institute’s innovative technology, the multi-carrier reflectometry, combined to an embedded system, allows detecting and localising in real time steady and intermittent defaults (below one millisecond) in cable harnesses several hundred meters long and possibly several kilometres long. Thanks to this process, it is possible to monitor cables online without disturbing the operational signals. It is also possible to respect the electromagnetic compatibility standards and to deploy several sensors on the same network in order to take into account the high degree of network’s complexity.
Initially set up on an electronic card this cable diagnosis technology is now integrated into a chip. It gave birth to WinMS start-up spun-off by List in 2012.

Applications

Aeronautics, railway, building, infrastructures, energy sectors.
