Electrical Energy Generating for Anti Tempering Devices using Piezoelectric Effect

ABSTRACT: The objective of this proposal is to demonstrate the feasibility of an electrical energy generation using piezoelectric devices, which can be used for power solution for sensors detecting tampering engineering and reverse engineering for core electronics devices such as CPU, DSP, or FPGA. BENEFIT: Many Anti-tamper technologies need power to operate properly. However, deploying and maintaining batteries for powering these AT devices up present enormous challenges to the DoD logistic supply chain pedgree. The proposed solution harvests energy using piezoelectric effect. The piezoelectric device also can detect vibration or noise potentially induced by weapon systems operated in severe environment and destructive analysis for tampering engineering. The electrical potential generated by the piezoelectric device will be harvested to power AT devices up without a dedicated battery. The energy harvesting and storing techniques can be also used in the area of commercial IP protection applications.
