Abstract Scope |
Printed electronics are increasingly investigated for space missions in applications such as sensors, interconnects, and antennas. Aerosol jet printing (AJP), with its ability to deposit high-resolution features on non-planar substrates, is considered a promising technology for these applications. However, temporal stability of electrical performance and variability across nominally identical AJP-fabricated devices remain insufficiently characterized. This work presents initial results evaluating the electrical behavior and reliability of printed silver electrodes. Temporal stability is assessed by recording current responses over 10,000 cycles under pulsed DC voltages and stepwise sweeps. Device-to-device variability is evaluated by comparing cyclic electrical responses across devices fabricated under identical conditions. The effects of process parameters, including layer count, sintering time, and focusing ratio, are also investigated. These results establish critical links between processing, structure, and performance, and are expected to guide printing and sintering strategies to achieve reliable and repeatable performance in printed components for future space systems. |
