HydroGraph Clean Power Inc. (CSE: HG) (OTCQB: HGRAF) (“HydroGraph” or the “Company”), a leading producer of ultrapure graphene, today announced that it has been awarded U.S. Patent No. 12,378,948 for a novel actuator technology that uses electrically conductive porous carbon materials, including HydroGraph’s proprietary Fractal Graphene™, to generate controlled mechanical force.
This is the first U.S. patent granted for an invention developed in HydroGraph’s laboratories, part of the company’s strategy to expand its intellectual property portfolio beyond the foundational graphene synthesis patents licensed from Kansas State University. In addition, HydroGraph now has 11 additional patent applications pending for various material innovations and applications.
The patented design uses the fractal, highly porous structure of HydroGraph’s Fractal Graphene™ to create an electrothermal actuator. By applying a small voltage, Joule heating expands the trapped air in the material, creating movement and force. Unlike conventional actuators HydroGraph’s device delivers fast, quiet and scalable power generation. A unit the size of a finger can generate approximately one newton of force, with designs scalable to larger outputs.
The global actors The market was valued at $66.95 billion in 2024 and is expected to reach $71.22 billion in 2025 to approximately $100.41 billion in 2030, reflecting a compound annual growth rate of approximately 7.1 percent. This steady growth highlights the growing demand for actuator technologies that can deliver greater efficiency, lower noise and better adaptability in industries such as automotive, manufacturing, robotics and consumer appliances.
“Fractal Graphene™ is unique in that its structure is more than 95 percent air, giving it an extraordinary ability to generate power during electrical heating,” says Dr. Ranjith Divigalpitiya, Chief Science Officer of HydroGraph and co-inventor of the patent. “In fact, it is essentially electrically conductive air. This patent shows how the intrinsic properties of our material can be translated into new types of actuators. While further validation and development are needed, the scientific foundation laid here opens a path to motion technologies that are lightweight, quiet and adaptable at different scales.”
The invention has broad claims covering porous carbon materials such as carbon black, graphite, carbon nanotubes and graphene foams. Possible applications include:
- HVAC and Building Systems: Replacement for wax or PTC based hydronic valve actuators.
- Consumer appliances: Quiet low-voltage actuators for dishwashers, coffee/steam machines and other household items.
- Automotive thermal management: compact, EMI-immune actuators for EV and ICE cooling circuits.
- Microfluidics and diagnostics: lab-on-chip devices where small, fast actuators are crucial.
- Aerospace and robotics: lightweight, scalable and quiet operation in environments where motors are impractical.
“Securing this patent is an important milestone in broadening HydroGraph’s intellectual property portfolio,” said Kjirstin Breure, CEO of HydroGraph. “While our core focus remains on the commercialization of high-purity graphene, this achievement underlines the versatility of our technology platform. Intellectual property of this nature strengthens our position over the long term and provides opportunities as we evaluate applications where our materials can create measurable value. We look forward to working with potential partners to explore the most appropriate avenues for this innovation.”
The patent positions HydroGraph to explore the development of a family of actuators ranging from cost-sensitive carbon black versions to premium graphene foam designs.
