Liten is a major European research institute and a driving force behind the development of the sustainable energy technologies of the future. The institute is spearheading the EU’s efforts to limit dependency on fossil fuels and reduce greenhouse gas emissions in three key areas: renewable energy, energy efficiency/storage and development of materials.
Our platforms, sophisticated tools for industry & the scientific/technical infrastructure/expertise to overcome technological hurdles
Liten's research teams work across a vast portfolio of renewable energy technologies. Cutting-edge photovoltaic technologies are developed at INES, the French National centre for solar research and R&D with Hydrogen and Biomass activities being managed from the LITEN's main site in Grenoble, Rhone-Alpes.

Printed components: technologies and processes for tomorrow’s printed organic electronics industry
Since the mid-2000s, Liten has been investing its resources in the research and development of techniques for printing electronic components onto large-area and flexible substrates. This disruptive technology is fundamentally different from traditional silicon-based technologies, as the components are formed by printing successive layers of ink with specific properties—conductive, insulating, semiconductive, or ferroelectric—onto either flexible or rigid surfaces. The technology has considerable benefits: it allows manufacturers to produce electronic devices that are flexible, thin, and conformable; that can be integrated onto different types of media (plastic, paper, textiles); and that can cover large areas. This method drives down production and system costs, paving the way towards new applications that turn simple surfaces into “smart” surfaces.Working in partnership with a textile manufacturer, Liten initially concentrated its efforts on developing printed electronics applications for consumer devices and smart packaging, with integrated printed sensors (temperature, pressure) and simple electronic circuits containing printed transistors. In a later partnership with the company Isorg, we turned our attention to the new technological field of electro-optical sensors (photodetectors), which are marketed for diverse uses such as non-contact human-machine interfaces (HMI), logistics, smart buildings, and more. The technology gives surfaces the ability to “see” through the optical sensors printed onto them to detect objects or movement. More recently, we have been exploring printed electronics applications in healthcare (endemic diseases), wellness (cosmetics), and the silver economy (at-home monitoring services for assisted living). To that end, Liten partnered with Leti on several projects geared towards developing biosensors, including lactate sensors that track muscular activity, carbon dioxide detectors that monitor sleep apnea, and blood glucose sensors for diabetes patients. We have already developed prototypes of these different biosensors and are currently in negotiations with several companies who work in each of the aforementioned markets. The Internet of Things also presents itself as a very promising market because of its reliance on various types of sensors (physical, biological, chemical), circuits, antennas, and ultra-high frequency (UHF) components—all of which can be printed and developed at Liten. In terms of energy, low-cost sensors can be inserted into proton exchange membrane fuel cells (PEMFC) for real-time monitoring, or into batteries to monitor certain critical parameters such as the battery’s charge.Over 30 researchers have been assigned to printed electronics, and their expertise covers the entire value chain, with know-how in fields like materials, printing technologies, component design, electrical characterization, and component reliability. They lead their work both in Liten’s laboratories and at the CEA’s large-area printing platform, PICTIC. The platform gives manufacturers the opportunity to make prototypes and to test equipment before making any of their own investments. PICTIC plays an important role in the preparatory stages of technology scale-up and transfer.Experts worldwide concur: in the next twenty years, printed organic electronics will be one of the key breakthroughs in the high-tech industry. And the reward will be a big one, with a market potential estimated at over $50 billion as early as 2020. For the past ten years, Liten has been preparing for this transition and has positioned itself as one of the five most advanced research centers in the world in this field.
Priming printed organic electronics applications for future adoption by technology manufacturers
