Squeezing Out More Power

Piezoelectric Material Harvests Record Amount Of Energy.

Technology Review (1/29) reports, “Researchers at Princeton University have created” a piezoelectric material that “can harness 80 percent of the energy applied when it is flexed–four times more than existing flexible piezoelectric materials.” The researchers used PZT, “the most efficient piezoelectric material known, but its crystalline structure means that it must be grown at high temperatures, which normally melt a flexible substrate. The Princeton researchers, led by mechanical engineering professor Michael McAlpine, got around this by making PZT at high temperatures and then transferring thin ribbons of the material onto silicone.” The researchers are particularly focused on biomedical applications.

    I am hopeful that the new developments in piezoelectric materials will one day be a significant part of home electrical power systems. The high temperature atmosphere required to produce the crystalline structure materials might be obtained in a oxygen deprived environment such as higher atmosphere locations.
