Abstract

A (K, Na)NbO₃ (KNN)-based lead-free piezoceramic for a piezoelectric energy harvester (PEH) should exhibit a large k_ij, Q_m, d_ij, and a small ε^T₃₃ to generate a large power output. Texturing was used to enhance the piezoelectricity of KNN-related piezoceramics. In particular, the k_ij and d_ij values of the KNN-based piezoceramics were considerably improved after texturing along the [001] direction, with a small change in the ε^T₃₃/ε₀ value, indicating that the [001]-textured KNN-based thick films are good candidates for use in PEHs. The 0.97(K_0.5Na_0.5)(Nb_0.93Sb_0.07)O₃-0.03CaZrO₃ [KN(N_0.93S_0.07)-CZ] thick film was textured along the [001] direction, and this thick film exhibited a large k_p (0.57) and d₃₃ × g₃₃ (25.7 pm²/N), which is the largest d₃₃ × g₃₃ of the KNN-based piezoceramics reported to date. A cantilever PEH fabricated using the textured KN(N_0.93S_0.07)-CZ thick film exhibited a power density of 21.4 μW/mm³ at the resonance frequency. This is the highest power density observed for PEHs fabricated using lead-free piezoceramics. The PEH also exhibited a power density of 0.023 μW/mm³ at the off-resonance frequency. Therefore, the textured KN(N_0.93S_0.07)–CZ thick film is a good candidate for use in PEHs.
