Piezoelectric Energy Harvesting covers the conversion of mechanical energy into electrical energy using piezoelectric materials. You'll learn about crystal structures, piezoelectric coefficients, and device design principles. The course dives into energy harvesting circuits, power management, and applications in wearable tech and IoT devices. It also explores material selection, fabrication techniques, and performance optimization of piezoelectric harvesters.

Is Piezoelectric Energy Harvesting hard?

Piezoelectric Energy Harvesting can be challenging, especially if you're not solid on your physics and materials science basics. The math can get pretty intense, with lots of equations describing mechanical stress and electrical charge relationships. That said, most students find the hands-on lab work and real-world applications super interesting, which helps balance out the tougher theoretical parts. It's definitely not a walk in the park, but it's manageable if you stay on top of the material.
