4D printing of electroactive polymers  as a new tool for hybrid dynamic structures for optical-quality surfaces shape control

 

 

Optical communication and remote sensing (ground and space) are the next frontiers of high-speed communication and civilian space surveillance technologies. Each requires precise glass mirror technology. As a result, communication and remote sensing systems are currently limited by cost restrictions and industrial restrictions of their optics. We propose to develop a new and interdisciplinary technology to break the cost, surface density, rigidity and regularity limit with new (non-abrasive) additive manufacturing: Live-MetaOptics. The new components and main objectives are: to develop a contactless glass from Float Glass commercial thin glass; develop a mirror with an active form control system via hybrid 4D printing with force actuators and ultra-precise sensors; a prototype mirror the 4D printing of 0.5m; develop optical and co-phasing calibration for multi-mirrors.
This collaboration is an interdisciplinary project between two laboratories with complementary specialties in R & D - the CRAL / CNRS specialist in optical instrumentation for remote sensing on the ground and space - and the LGEF / INSA specialist in 4D printing and coupling. multi-physics and more particularly electro-active materials and systems, which are at the heart of our project.
