This first edition of the GdR SYMPHONIQUE Annual Meeting will bring together members of the ultra-sensitive mechanics community to address the development and exploitation of ultra-sensitive mechanical measurement. Building on the legacy of the GdR MecaQ, whose primary focus was the study of fundamental processes in interferometric motion measurement, SYMPHONIQUE expands its scope to encompass all concepts of ultra-sensitive mechanical measurement and engage with disciplinary fields capable of addressing the new scientific challenges that have emerged in the field over the past decade.

Registration to the meeting is free but *mandatory*. It includes access to all sessions, free meals and a free attendance to the conference dinner (6th Oct. evening). 

Please do not hesitate to submit your contribution(s) at your earliest convenience. Please note that we encourage all participants, and in particular early career researchers, to submit and bring a poster. A poster prize will be awarded to three peer reviewed posters.

Submission deadline: Sunday 23th August 2026, 23.59 CEST (Paris time)
