GREMAN is a research laboratory of the University of Tours, CNRS and INSA Centre Val de Loire focusing on materials, devices and systems for the conversion and management of electrical energy with a main objective of improving energy efficiency.
Thanks to the skills of its four teams which cover materials sciences (physics and solid-state chemistry) and engineering sciences (microelectronic, acoustic, electrical engineering), activities start from the synthesis of new materials with remarkable properties until the development of components and devices, and their integration into electrical systems.

The applications relate to new microelectronic devices, transducers and ultrasonic systems, electrical energy conversion systems.
These research activities include fundamental studies using simulation tools and models developed within the laboratory. They also rely on several technological platforms, particularly on CERTeM (R&D center for microelectronics) for manufacturing and multi-physical and multi-scale characterization.


GREMAN is particularly involved in education through five master's degrees in Tours and Orleans universities:
GREMAN's teaching researchers are also involved in courses at University Institutes of Technology of Tours and Blois, the Sciences and techniques education and research faculty as well as in the engineering schools : Polytech' (Graduate school of engineering of Tours university) and INSA Centre-Val de Loire (member of the National Institutes of Applied Sciences based in Blois).
