Abstract

This paper describes the fabrication process of thick-film lead free piezoelectric ceramics, consisting of barium titanate (BaTiO3), borosilicate, terpineol, on alumina (Al2O3) substrate. The BaTiO3thick-films piezoelectric are prepared by screen printing. Suitable ratio for the paste composition is crucial to ensure printability and functionality of lead-free piezoelectric ceramic. Ag/Pd is deposited as the lower and upper electrodes to form a unimorph piezoelectric device. The thick-film which contained 50wt. % BaTiO3, 10wt.% borosilicate, and 20wt.% terpineol demonstrated the optimal piezoelectric properties with the maximum piezoelectric charge coefficient of 17 pC/N. The thick-film was also inspected under SEM to investigate the quality of the films.
