A promising new piezoelectric material, 100 times more efficient than quartz, is being developed at Princeton University. Called PZT, it's a rubber film made up of silicone and naonoribbons of lead zirconate titanate. The material can convert up to 80% of kinetic energy into electricity, and its flexible nature allows for a wide range of uses.
