  • Whether it’s a question of limited resources, pollution, the quest for efficiency or the precautionary principle, no economic activity escapes the environmental challenge. Industry is revisiting its varied processes, transport is exploring new avenues, the powerful energy sector itself is in the throes of reinvention. The common thread to all of these new dynamics: the need to enrich all systems with the black gold of the 21st century, data.
    Microelectronics is presented with a contradictory challenge : to be the engine that serves these data-hungry new markets, while containing the ecological footprint of large information systems.
    At the heart of a research organization dedicated to energy issues, Leti has long been aware of these challenges and offers its partners a complete set of technological capabilities, from materials to networks, in order to balance the difficult economic and environmental equations of a world in transition.
  • Unmatched in its flexibility of usage and conveyance, electrical energy continues to find new uses at the very heart of man’s activities. It is the lifeblood of today’s transport, thermal systems and mobile devices, all of which control ever larger data volumes. To meet both ecological and economic challenges, all these systems require electronic technologies designed with perpetual respect for optimum energy efficiency: a concern that is more than ever omnipresent in  Leti’s technological developments.

  • Urbanization and man’s evolving lifestyle, mobility, communication, exchange and production all exert increasingly unsustainable environmental impacts. Reducing them means revisiting our activities in the light of the maximum available information: a “smartification” dynamic, for which Leti offers its partners its proven know-how and all the technologies required for optimizing their platforms and complex systems.

  • The need to monitor continuously quality and changes in our environment, air, water and global resources has now been clearly identified, but the solutions to implementing this monitoring process are less obvious. They involve combining multiple key individual technologies, optimum management of the energy made available to these technologies and networking capacity to ensure efficient feedback of the data they generate. Leti implements a broad range of such solutions.
