NASF Foundation Research Board Develops Flexible Hybrid Electronics via Confined Electrochemical Printing
The NASF Foundation Research Board selected a project in 2022 focused on scalable manufacturing processes for hydrogen fuel cells and electrolysis cells. In Q4 2025, the UTD research group detailed advances in printable electronics, addressing confined printing transfer, establishing printing parameters, and measuring electrical conductivity of copper lines. The method demonstrated effective patterning with resistivities of 3.39 μΩ·cm, near bulk copper levels.

In 2022, the NASF Foundation Research Board initiated a project on electrodeposition for hydrogen fuel cells and electrolysis cells. By Q4 2025, the UTD research group shifted focus to printable electronics.
This final report outlined three objectives: clarifying the confined printing transfer process, establishing printing parameters for various geometries, and measuring the electrical conductivity of printed copper lines. A three-step transfer sequence was identified for reliable pattern release. The confined printing method resulted in continuous copper films with resistivities near bulk copper levels at 3.39 μΩ·cm, validating its effectiveness for high-quality conductive patterning.
