Abstract
The technical field of the invention is that of devices for igniting pyrotechnic charges, and more specifically those suitable for small pyrotechnic charges which can be found in microsystems such as microvalves or micropumps. The subject of the present invention therefore relates to a device for igniting a solid pyrotechnic charge, comprising a heating device. The main characteristic of this ignition device is that the heating device is a conducting track (2) obtained by depositing a conducting ink on the pyrotechnic charge (1), it being possible for this deposition to be carried out by screen printing or by inkjet.
