You probably learned in high school what the piezoelectric effect is: a phenomenon where an electromotive force is generated by applying mechanical stress to a material. So far, piezoelectric devices used a material called lead zirconate titanate (PZT). However, PZT is expensive and contains lead, which is bad for the environment. Progress does happen, though, […]

Researchers from the University of Notre Dame in the US have designed a PZT (lead zirconate titanate) piezoelectric device that resembles skin (they called it the EH skin) and that can harness energy from the mechanical work applied to it. The new device can be used in a variety of applications, ranging from wireless sensor units to patches that get energy from vibrations and pass it on to the grid. The sample they tested got as much as 3.7 mW.
