In order to develop a new type of transducer for insensitive explosive devices, the problems in the film forming process of AlN ceramic surface were studied and the solutions were given. By comparison of ignition experiments, the surface roughness and average ignition current of the TaN film energy commutator prepared on the surface of polished AlN ceramics were smaller and higher. It met the technical requirements of insensitive explosive devices, which provided a new way for insensitive explosives.

In order to improve the safety and energy exchange efficiency of electric thermal pyrotechnic devices, a new energy exchange element technology of high energy metal (W) film/aluminum nitride ceramic was explored by taking advantage of the high thermal conductivity of aluminum nitride ceramic materials. High-temperature co-fired ceramics were used to prepare the new system energy exchangers, and the prototype of the new system energy exchanger of high-energy metal (W) film/aluminum nitride was obtained. Through infrared microscopic test and ignition performance test, the new system energy exchanger of high-energy metal (W) film/aluminum nitride can satisfy the 1A1W5min non-ignition test, and the ignition current of 50% is 2.80 A. The response current of 99.9% is 3.54 A, and the response current of 0.1% is 2.06 A, which provides technical support for the application of a new type of passivated electric thermal pyrogenic product.

“…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 ]. Among these materials, TaN is widely used because of its high stability at high temperatures, antioxidant properties, corrosion resistance, and low cost of manufacturing [ 18 , 19 ].…”

Initiating explosive (IE) devices are widely used in the aerospace, resource mining, and basic industries and other fields. With the improvement in processing technology, IE devices are developing towards miniaturization and intelligence. As an important component of the energy conversion of IE devices, the output characteristics of micro energy conversion (EC) elements directly affect the ignition performance of IE devices. Hence, this paper researches the output characteristics of EC elements under external excitation. Firstly, the fabrication process of the EC element is introduced, and the finite element analysis model of the temperature field is deduced. Secondly, the simulation model of the output characteristics of the EC element is constructed, the validity of the model is verified through experiments, and the basic characteristic parameters of the EC element are determined. Finally, four shapes of EC element structures are designed, the corresponding output characteristics under constant current excitation are analyzed, and the temperature and current field distributions of the EC elements with different shapes are given. The experimental and simulation results show the effectiveness of the analysis results in this paper, and the influence of different shapes on the insensitivity of EC elements is given through comparative analysis, which provides support for the design of micro structure EC elements.
