Piezoelectric energy

Piezoelectric energy is a form of electric energy produced by certain solid materials when they are deformed. (The word piezo has its roots in the Greek word piezein meaning to press. ) Discovery of the piezoelectric effect is credited to Pierre and Jacques Curie who observed in 1880 that certain quartz crystals produced electricity when put under pressure. 

The terms involving (SE)2 and (SX)2 are the electrical and mechanical energy densities, and those involving 5E5X the piezoelectric energy densities. It follows from Eq. (6.35) that...

Whiter et al., 2014). The confined geometry of the template promotes the production of an oriented p crystalline phase required for superior piezoelectric energy harvesting, without the electrical poling. This room-temperature fabrication process is attractive and can he implemented at a large scale (Liew et al., 2015).

Electrospinning technique has been used not only for the deposition of polymeric nanofibres but also for the production of ceramic nanofibres of PZT. PZT is commonly used in micro- and macro-scale piezoelectric energy harvesting devices due to its high electro-mechanical coupling coefficient of -500-600pC ) as compared...
