It is well known that, Piezoelectric classified into Ferroelectric and nonferroelectric materials, both types of materials were utilized for energy harvesting. What the difference between the Ferroelectric materials and the non-ferroelectric materials in terms of voltage signal and current generation?. for more clarification which of the provide higher voltage, current or electric power ?. Thank you
Nano materials are close to atomic level actually at electronic level which has high energy, therefore the Nano materials have higher energy than normal size materials
The ferroelectric materials are those materials which display ferroelectric ordering below certain temperature. Ferroelectric materials also show a hysteresis loop between electric field and polarisation below ferroelectric ordering temperature. However, ferroelectric materials do not display such type of properties.

Ferroelectrics are usually defined as polar materials that display polarisation hysteresis. This is a functional definition. A structural definition exists too, based solely on symmetry arguments. The structural definition, useful e.g. for design of new materials, says that a ferroelectric is a material that underwent a phase transition from a parent higher-symmetry phase into a ferroelectric phase, such that the polar directions in the ferroelectric phase are linked to each other by lost symmetry operations of the parent phase.
