PYROTECHNIC MICROSYSTEM AND METHOD FOR MAKING SAME

摘要

A pyrotechnic microsystem (7) comprises a substrate with at least two distinct electrical initiation zones of a pyrotechnic material deposited on it. The same deposit (721) covers both zones and is sufficiently thin (less than 100 mu m) for the initiation of the pyrotechnic material in one zone to remain localized and not to be propagated to the other zone, while being sufficient to generate a predetermined quantity of gas. The substrate is made from a number of assembled layers (71, 72, 73, 74), with the pyrotechnic layer comprising one of them, e.g. in the form of a layer of a nitrocellulose-based varnish.
