NASA Langley's Piezoelectric Energy Harvesters Webinar

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.
These two new energy harvesters can produce more than ten times the power output capable from commercial devices at the same level of vibration. Not only that, the ability to couple more mechanical energy with the piezoelectric materials allowed both devices to operate more effectively in the resonance mode and at off-resonance frequencies than anything currently on the market.
But don’t take our word for it. Come see for yourself.
