Fabrication of piezoelectric composites using high-temperature dielectrophoresis

In this paper, we present a method to create a highly sensitive piezoelectric quasi 1–3 composite using a thermoplastic material filled with a piezoelectric powder. An up-scalable high-temperature dielectrophoresis (DEP) process is used to manufacture the quasi 1–3 piezoelectric polymer-ceramic composites. For this work, thermoplastic cyclic...

Enhancing energy harvesting potential of (K,Na,Li)NbO₃-epoxy composites via Li substitution

In this study, the influence of Li substitution on the piezoelectric performance of lead-free K_0.5Na_0.5NbO₃ (KNN)-epoxy composites is explored. KNN piezoceramic particles modified with 0-12 mol% of Li are prepared via a double calcination technique, resulting in a perovskite particulate which transitions from...
