? 2022A self-destruction module for information storage equipment (ISE) that releases a detonation wave via energetic materials (EMs) is discussed. The module uses an energy-grooming actuator (EGA) to isolate EMs from external electronic systems to improve security. The response time of removing electrical constraint for EMs, the stress transferring of detonation wave in air domain and the response time of ISE physical self-destruction are obtained via COMSOL, LS-DYNA, the module function integration is realized by stacked graphene and platinum films and in-situ copper azide synthesis. During tests, the response time of removing electrical constraint for EMs by EGA was 0.942 ms. When a voltage pulse (below 5.5 V) exploded the EMs, the detonation wave was generated under 61.8–63.2 μs to destroy the ISE. Overall, ISE physical self-destruction was realized with a lower driving energy, a fast response time and security control for the EMs. The module has potential applications for information security.
