摘要
Screen-printed lead zirconate titanate (PZT) thick film actuators are beneficial for miniaturized devices due to their flat profile and accurate net-shaped fabrication. Sintering progress and piezoelectric performance depend on the type and amount of sintering additive. Cantilever structures were fabricated by the use of screen printing technology with a systematic variation of the sintering additive content and for two different piezoceramic base materials. Their microstructure, small and large signal properties were characterized. Based on the experimental data we developed an actuator frame to lift a micro-lens array within a low-profile microscope by 115 mu m.
