Description

The Piezoelectric Energy Harvesting STEM Kit is an educational science kit that demonstrates how mechanical pressure can be converted into electrical energy using piezoelectric sensors. When force is applied to the piezo discs by pressing or stepping on them, they generate electrical energy that is conditioned through the onboard circuit and displayed on an LCD screen.

This ready-to-use educational model helps students understand the principles of renewable energy, piezoelectricity, voltage generation, and energy harvesting. It is ideal for STEM education, engineering laboratories, science exhibitions, and practical demonstrations of sustainable energy technologies.
