Research Engineers Harvest Energy from Sound

Two engineers have developed a way to harvest energy from sound using piezoelectric materials. Stephen Horowitz and Mark Sheplak created an aluminum membrane that is extremely sensitive and has the ability to turn sound vibrations into an electrical charge.

During the research, Horowitz and Sheplak recognized that they could utilize a jet engine that produces more than 130 decibels to change the sound into electrical energy. The next step of the project is attaching the membrane to a special liner that cancels specific frequencies and decreases engine noise.
