From the project

Wearable piezoelectric energy harvesting system that converts foot motion into electrical energy for low-power wearable and biomedical applications.

A wearable piezoelectric energy harvesting system designed to convert mechanical energy generated by human foot motion into usable electrical energy for low-power wearable and biomedical applications.

The implemented system uses an LDT2-028K piezoelectric sensor mounted on a cantilever structure, followed by DB107 full-wave rectification, capacitor-based energy storage, and MOSFET-based power switching between the harvested-energy path and a rechargeable battery backup.
