摘要：
This study investigates the preparation of a composite material composed of lanthanum strontium nickelate oxide (LSNO) and a resin to be used as fingerprint identification materials. The study showed that the dielectric constants of the composites influence fingerprint discriminability. The highest dielectric constant was 112 at 1 MHz, and the lowest impedance of the composites was obtained from the LSNO powders prepared using La:Sr:Ni of 1:3:1 and subjected to 1200 degrees C calcining temperature for 1 h. Composites with 50% of the LSNO powders (La:Sr:Ni = 1:3:1) exhibited the highest fingerprint discriminability.
