PERTH, Australia, Sept. 25, 2025 /PRNewswire/ -- ASX-listed Strategic Elements Ltd (ASX: SOR) is pleased to announce that Energy Ink — a printable ink that generates electricity from moisture in the air — has, for the first time, been used to manufacture thousands of prototype cells in a commercial facility using printing equipment commonly deployed across consumer, defence and healthcare sectors. This achievement establishes the foundations for collaboration with international printed electronics centres and potential end-users. Through these partnerships, Energy Ink may be evaluated and co-developed into prototype cells and product demonstrators within industrial-style facilities. Building this capability broadens the opportunity base and creates a clear pathway from research conducted in Australia to active engagement with global industry. Transfer Program Outcomes Over 2000 prototype Energy Ink cells were successfully fabricated in a single production run and validated, confirming reproducibility in a commercial facility. In addition, 30 multi-cell arrays were connected and operated continuously for seven days at the target baseline power.
Fabrication in a commercial facility Energy Ink cells demonstrating reproducibility under industrial processes. High Yield Achieved 2,051 of 2,052 cells (99.95%) passed compliance testing for open-circuit voltage and short-circuit current. Connected arrays manufactured Successfully validated that interconnected cells can operate as functional arrays. Multiple A5 sheets produced Marking progress toward sheet-level fabrication, essential for scaling into demonstrators and eventual commercial deployment. Energy Ink is being developed in collaboration with a world-class materials science team at the University of New South Wales (UNSW). UNSW is globally recognised for its expertise in functional materials and electronic printing with state-of-the-art nanofabrication, printing and characterisation facilities. The technology has been supported with more than $5 million in competitive Australian Research Council (ARC) grants, including prestigious ARC Industry Fellowships. Further Testing Earlier development showed the low-power, disposable Energy Ink prototype powering a skin patch with two 4 cm × 4 cm cells (32 cm² total area) at 2.5 µW/cm². The transfer fabrication program scaled this performance across thousands of cells. In the transfer program, 2,051 cells out of 2,052 achieved 100% yield for both open-circuit voltage (>1.2 V) and short-circuit current compliance. A 7-day constant current test of 30 arrays (27 cells in each array) was then conducted at a capped 10 µA per cell to match the skin patch baseline. All 30 arrays maintained continuous output, each sustaining 270 µA (0.27 mA) for the 7-day period, with minimum power density of 2.5 µW/cm². Testing was performed under semi-controlled indoor humidity of 55%–70% RH, consistent with printed electronics facility environments. Development Pathway & Challenges With reproducible fabrication of prototype Energy Ink cells outside the laboratory now achieved, detailed characterisation will be undertaken to establish a robust dataset. The next objectives are to:
Energy Ink remains at an early stage, with challenges ahead:
