A DARPA project called Energy Harvesting focuses on the use of this phenomenon for military purposes, and includes an attempt to power field equipment with generators in the soldiers' shoes. Atomic force and scanning tunneling microscopes use the converse effect to keep the sensing needle close to the probe. Materials exhibiting it include ceramics with tungsten-bronze structures or containing perovskite, the compound berlinite, and polyvinlidene fluoride, which exhibits levels several times greater than quartz.
