Study of MEMS Based Micropyrotechnic Igniter

Abstract

Micro-electro-mechanical system (MEMS) have recently seen their field of application extended to military. This is mainly due to the fact that MEMS technologies present a great to reduce the mass, cost, power consumption, while improving the reliability, performance and smartness. Application of MEMS technology, the micropyrotechnic igniter are produced.The principle is based on the integration of lead styphnate (LTNR) material within a micropyrotechnic igniter, which is produced by MEMS with 3 by 3 micro-igniter. Each igniter contains three parts (the igniter chip, silicon chamber, lead styphnate). One import point is the optimization of the igniter process obtaining Ni-Cr bridges with about 13Ω, which is triggered by electrical power delivered to LTNR. The resistance of Ni-Cr bridges is used to sense the temperature on the LTNR which is in contact. The other one point is the optimization of silicon chamber process obtaining incorporate configuration of micropyrotechnic igniter. The ignition performance of micropyrotechnic igniter array are tested with ignition voltage less than 13V. The experimental results will deeply contribute to the micropyrotechnic system. This paper will discuss all these point.

Research on the Output Characteristics of Energy Conversion Elements under External Excitation

“…Enhancing the output characteristics of the EC elements is the main way to improve the ignition and insensitivity of IE devices [ 1 , 4 ]. To optimize the output performance of the EC elements, micro electro-mechanical systems (MEMS) technology has been introduced into IE devices, leading to the generation of high-performance micro EC elements [ 5 , 6 , 7 ]. Micro EC element materials mainly include semiconductor bridges [ 8 , 9 , 10 ], metal material membrane bridges such as nickel–chromiums alloy [ 11 , 12 ], tantalum nitride (TaN) [ 13 , 14 ], and composite materials [ 15 , 16 , 17 ].…”

Investigation on Properties of MEMS Based Micropyrotechnic Igniter

“…Micro-pyrotechnics can be defined as the integration of an energetic material into a multi-functional micro-system, for which the thermal, mechanical and chemical energy released by decomposition [8]. One particular system widely used in missiles, rockets, warhead and like device and that can efficiently takes profit of MEMS technologies is the pyrotechnical initiator and microfuze system [9][10]. This paper designs micropyrotechnic igniter refer to MEMS technology and micro-pyrotechnics.…”
