The essence of Lichens

D'où vient le nom Lichens ?

Our history

This incident inspired a PhD work: “the reduction in attenuation introduced by energy-efficient glazing”, led by Alejandro Niembro in collaboration with the Paper Technical Center, IMEP-LAHC and LCIS. The PhD, defended in 2017, focused on the development of flexible printable supports for filtering and adapting electromagnetic waves.

Under the supervision of Tan-Phu Vuong, Professor at INPG, our project was selected by SATT Linksium Grenoble Alpes for a maturation of 15 months. This phase resulted in the filing of a patent, underlining the unique and innovative nature of our solution.

In 2019, the project entered an incubation phase. Our startup aims to improve mobile connectivity in spaces where it is limited, such as buildings with reinforced thermal insulation glazing. Our solution, an adhesive film with conductive patterns, improves wave transmission and thus ensures better connectivity inside buildings.

On March 18, 2021, Lichens was created, continuing the research and development that had begun. Our mission is to facilitate access to telecommunications everywhere and for everyone, by responding to a modern challenge: reconciling thermal insulation and digital connectivity.

Recognition of the Deeptech project, obtaining the French Tech Emergence grant.

Winner of the R&D Booster competition in the Auvergne-Rhône-Alpes region.

Obtaining the status of an innovative young company.

Integration into Orange's 5G acceleration program.

In April 2014, the story of Lichens began with a surprising discovery at the Paper Technical Center in Grenoble. The IMEP team, meeting for an important academic review, faced a major problem: the total absence of a mobile signal in the new building.

This experience highlighted a little-known but critical problem: the unintended Faraday cage effect of modern buildings, due in particular to the metal oxide layer of energy-efficient windows, which strongly attenuates radio waves.
