【Abstract】 Aiming at the protection of high-security information storage media at the hardware level, research on low-drive energy self-destruction modules based on semiconductor bridge(SCB) and energetic material was carried out. The mathematical model of SCB plasma ignition, energy transfer and ignition of energetic material was established and the theoretical calculation was completed. The SCB multiphysics simulation model was built by COMSOL for its performance check. The test platform was built for the examination of ignition performance of SCB and energetic material. The simulation and experimental results show that the energetic self-destruction module has excellent ignition performance, which can detonate the SCB bridge area and make the bridge area temperature reach 2 700 K within 18 μs under the excitation of 5 V charging voltage, so as to excite 0.43 mg copper azide to detonate within 50 μs and produce a detonation wave. The energetic self-destruction module can implement energy transmission and destroy the target information storage medium, effectively avoid the theft of key information of the information storage medium, and ensure the security of the information storage medium.更多还原
