3d printed glass mems

Single chips integrating optical, mechanical and fluidic functionalities at the surface, or below it, can be fabricated with a single process on different transparent and chemically inert glasses. Some example of 3D micro-devices already developed are all-optical sensors for high accuracy force/displacement measurement, oscillators with micromechanical flexures and integrated optical components, optically transparent micro-actuators based on capacitive actuations.


CEA-LETI has chosen FEMTOprint to realize a Millimeter-sized particle sensor using a wide field of view monolithic lens assembly for light scattering analysis in Fourier domain.
