Within the Department for Industrial Partnerships of CEA-Leti, we met many industrialists », remembers Alexandre Paléologue, president of Morphosense. Very quickly, the engineer understood that one of the laboratory’s technologies could well meet the needs of large civil engineering groups wishing to
monitor the behavior of their infrastructures: bridges, dams, etc..
Originally designed to follow the deformation of a spine using motion sensors, it had not found a way out in the medical field. With two partners, Alexandre Paléologue created the start-up Morphosense in 2016, and adapted the sensors to this new market by improving their robustness and precision. This to be able measure in real time the static deformation (accuracy: 100 µm/m) and the vibrations of the structures.

Digital twins for even more precision
The start-up completes its offer in 2020 by implementing
the digital twins of infrastructures, which integrate their physical model, the data provided by the sensors, and new, those resulting from environmental measurements (wind, rain, swell, underwater current, etc.). ”
We can thus estimate at any point of the structure any type of data: cracks, twists, loosening of bolts… “, comments the founder. Enough to precisely monitor the fatigue of the installations,
theirduration of life and so
optimize predictive maintenance and therefore the associated operational costs. ”
For very expensive and inaccessible structures such as offshore floating wind turbines, this information is essential to control operating costs. », indicates Alexandre Paléologue. A
fifteen structures around the world are now equipped with the start-up’s sensors and six digital twins are operational on locks and wind turbines.
