Abstract

The selection of an optimal ferroelectric material according to the user requirements is a crucial as well as onerous task; examples of such requirements include high efficiency, sensitivity, wide operating temperature, and frequency range, compact size, low cost and low loss, etc. In this study, quality function deployment (QFD) in combination with multiple attribute decision-making (MADM) is employed for material selection. Pb(1-x)Lax)(ZryTi) (1-y))O3[PLZT (7/60/40)] (lead-based) and (K 0.44Na0.52Li0.04)-(Nb 0.84Ta0.1Sb0.06)O3(KNN-LT-LS) (lead-free) are found to be the top-ranked piezoelectric ceramics for transducer applications. PLZT (7/60/40) (lead-based) and 0.7Bi0.5Na0.5TiO-3-0.2Bi0.5K0.5TiO3-0.1(Bi0.5Li0.5)TiO3 (lead-free) are found to be best materials for energy storage applications.
