1. Principles of Piezoelectric Energy Harvesting

Piezoelectric materials possess the remarkable property of generating an electrical charge when subjected to mechanical stress or deformation. This phenomenon, known as the piezoelectric effect, forms the foundation of MEMS-based guided beam type piezoelectric energy harvesting devices.

In these devices, a piezoelectric beam is attached to a substrate and exposed to ambient vibration. The vibration causes the beam to bend, generating stress within the piezoelectric material. This stress, in turn, induces an electrical charge on the beam's surface, which can be harnessed to power various electronic devices.
