This article reviews the basics of ferroelectric energy harvesting cycles based on thermal fluctuation and mechanical confinement. In this context, five cycles (Olsen cycle, Clamped Olsen cycle, Electro-Mechanical cycle, Thermally Biased Electro-Mechanical cycle and New Power cycle) are studied for two different compositions (0.94Bi(1/2) Na-1/2 TiO3-0.06BaTiO(3) : BNT-6BT; 0.91(Bi1/2Na1/2) TiO3-0.07BaTiO(3)-0.02K(0.5)Na(0.5)NbO(3): BNT-BT-KNN;) which represents two distinct classes (based on domain wall rotation/motion) of ferroelectric materials. These can be classified as the composition with dominating impact of mechanical forces while the other is with ascendant thermal effects over the domain wall behavior.
