At the Mechanics and Interfaces Laboratory (LMI) at ENSTA, a bone distractor activated by a magnetic field is being developed. This innovative device enables jaw lengthening while significantly reducing suffering and pain. The technology was awarded the 2024 Prize by the Fondation des Gueules Cassées, an organisation born out of the association Les Gueules Cassées, founded in 1921 to support soldiers disfigured during the First World War. Furthermore, on 3 July, as part of Operation CIEDS 2025, you are invited to attend a thematic seminar, explore start-ups, and view posters on the topic “Health, Biology, CBRN” applied to defence.
