If we told you there’s a way to build piezoelectric energy harvesters that can produce more than ten-times the power output of commercial devices vibrating at the same frequency, would you believe us? It’s true! The key is to integrate stacks of polycrystalline lead zirconate-titanate Pb(Zr,Ti)03 (PZT) ceramic in design concepts that amplify your input forces, resulting in higher efficiency. And we’ll show you two ways to do that.
