We are leading the development of an innovative technology for a new lightweight hybrid meta-material, as well as self correcting active and deformable mirrors. This cutting-edge technology relies on three critical reserach and development:
- Precise processes for shaping fire-polished sheet glass.
- A dynamic hybrid metamaterial structure (HM-MS) that incorporates 3D-printed flexible electrodes and electroactive polymer actuators. This structure is designed to support the mirror and correct any deformations caused by atmospheric disturbances, thermal variations, gravitational effects, and wind loads.
- A multi-sensing metrology and calibration system that enables real-time closed-loop control.
These advancements in meta-structures are expected to produce cost-effective, lightweight, and integrated optoelectronic systems, showcasing novel remote sensing capabilities for both terrestrial and space-based platforms. In this manuscript, we provide a comprehensive update on the ongoing research and development initiatives related to the HM-MS technology. This initiative is funded by the Horizon European Innovation Council (EIC) as part of the active EIC Live-Mirror Consortium (Horizon EIC #101099220) and the deformable PEPR Origins FlexSiMirror project (ANR-22-EXOR-0004), funded by the French National Research Agency under the France 2030 program.
