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 ((0.5PbZrO 3 ‐0.5Pb(Ni 1/3 Nb 2/3 )O 3 : ( PZ ‐ PNN ) and 0.9Pb(Zr 1/2 Ti 1/2 )O 3 ‐0.1Pb(Zn 1/3 Nb 2/3 )O 3 : (0.9 PZT ‐0.1 PZN )). PZ ‐ PNN is depicted to illustrate an energy density of 70 kJ/m 3 under the conditions of 0–106 MP a applied stress and 1–15 kV/cm electric field. On the other hand, a maximum energy density of 50 kJ/m 3 is obtained for 0.9 PZT ‐0.1 PZN under ambient conditions of 0–173 MP a compressive stress and 1 to 18 kV/cm electric field.
