Application Research of Self-powered Technology in Smart Packaging

In view of the drawbacks of the power supply method for smart packaging, this paper proposes a scheme to apply electromagnetic vibration energy harvesting technology to smart packaging. To verify the feasibility of self-powered devices applied to smart packaging, the energy output of the experiments under 2 g excitation and 0.5 g excitation was tested experimentally. The results show that the self-powered device can reach peak-to-peak output voltage of more than 4 V in the sweep experiment under 2 g acceleration excitation. The output voltage exceeds 2 V at 0.5 g fixed frequency excitation, which can provide a maximum output power of 1 mW. The experiment verifies that the energy output of the electromagnetic vibration energy harvesting device can meet the work of low-power sensors. The analysis concludes that the electromagnetic vibration energy harvesting device has the potential to be applied to smart packaging.
