Abstract

<abstract abstract-type="main" id="ijac12364-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Present study introduces a novel energy conversion cycle for giant electro‐mechanical energy conversion using ferroelectric materials. The proposed cycle is used to perform indirect measurements for harnessable energy densities of two well‐known configurations ((0.5PbZrO₃‐0.5Pb(Ni_1/3Nb_2/3)O₃: (PZ‐PNN) and 0.9Pb(Zr_1/2Ti_1/2)O₃‐0.1Pb(Zn_1/3Nb_2/3)O₃: (0.9PZT‐0.1PZN)). PZ‐PNN is depicted to illustrate an energy density of 70 kJ/m³ under the conditions of 0–106 MPa applied stress and 1–15 kV/cm electric field. On the other hand, a maximum energy density of 50 kJ/m³ is obtained for 0.9PZT‐0.1PZN under ambient conditions of 0–173 MPa compressive stress and 1 to 18 kV/cm electric field.</p> </abstract>
