Circuit Documentation

Summary

This circuit consists of multiple piezo sensors, bridge rectifiers, a PowerBoost 1000 Basic Terminal USB, and a 18650 Li-ion battery. The piezo sensors generate AC voltage when subjected to mechanical stress, which is then rectified by the bridge rectifiers. The rectified DC voltage is used to charge the 18650 Li-ion battery, and the PowerBoost 1000 Basic Terminal USB boosts the battery voltage to a stable 5V output.
