Research on Energetic Micro-Self-Destruction Devices with Fast Responses

Area of Science:

• Materials Science
• Information Security Engineering
• Explosives Technology

Background:

• Information self-destruction devices are crucial for data security.
• Existing methods may lack sufficient destructive capability.
• A need exists for rapid and effective information destruction mechanisms.

Purpose of the Study:

• To develop and evaluate a micro self-destruction device for information security.
• To investigate the generation of GPa-level detonation waves for chip destruction.
• To optimize device parameters for maximum destructive impact.

Main Methods:

• A self-destruction model using nichrome bridge initiators and copper azide was established.
• An electrical explosion test system measured output energy and delay times.
• LS-DYNA software simulated detonation wave pressure based on material dosage and assembly gap.
• An optical probe measured the device's response time.

Main Results:

• Detonation wave pressure reached 3.4 GPa with 0.4 mg copper azide and a 0.1 mm assembly gap.
• This pressure is sufficient to cause irreversible damage to information storage chips.
• The device exhibited a rapid response time of 23.65 μs.

Conclusions:

• The proposed micro self-destruction device is effective for information security.
• It offers advantages in small size, fast response, and high energy conversion.
• The device shows significant potential for practical application in protecting sensitive data.
