Information self-destruction module design based on micro thermoelectric power generation and energetic materials

Information self-destruction modules (ISDMs) play a vital role in the information security area. In this paper, an ISDM based on the integration of a micro-thermoelectric generation mechanism (M-TEGM) with energetic materials (EMs) is proposed. On the basis of energy conversion relationship, an open-loop electromotive force is induced, and this energy will drive the EMs to release the detonation wave and realize information storage module self-destruction. During the tests, under the temperature difference (100 K), the open-loop electromotive force (3.86 V) is induced by the M-TEGM and can drive the EMs (0.37 mg copper azide) to generate a detonation wave (GPa) in 3.4 μs, which can physically destroy the information storage modules. This ISDM has advantages that include rapid response times, low drive energy compared with traditional information security technology.
