GREMAN is a research laboratory on materials, microelectronics, acoustics and nanotechnology of the University of Tours, CNRS and INSA Centre Val de Loire created January 1st 2012 by the merging of several groups located in Tours and Blois, France. Its expertise covers the value chain from materials science up to devices (components, sensors, transducers ...) and their integration. Fields such as electrical energy efficiency, power microelectronics and the use of ultrasonic waves are particularly targeted, for applications in industry, health and nomadic apparatus.

The activities of GREMAN are focused on four priority topics :

  • Functional oxides for energy efficiency: combinatory synthesis and nanostructuration.
  • Magnetic and optical properties of ferroic and electronic correlation materials.
  • Ultrasonic instrumentation and characterisation.
  • Energy, component, systems, microelectronics.
