In 2000, the EC funded MicroPyros project was initiated to develop technologies to merge energetic materials, MEMS devices and electronics in order to realize new performing micropyrotechnical systems (1), During the project, different designs and processes were evaluated to optimize the propellant ignition and the integration, a 2D addressing process was developed to control and command an array of pyrotechnical cells, and the technology was demonstrated through the fabrication and characterization of arrays of solid propellant thrusters. We report here on the development of designs and fabrication processes for the realization of millimeter and micrometer scale matrices of solid propellant micro-thrusters.
