New York Patent of the Month – April 2025
Pliant Energy Systems Inc has unveiled a patented device that transforms fluid motion into mechanical energy using flexible fins. This breakthrough, outlined in U.S. Patent No. 12,264,666 titled “Undulating transducer for energy harnessing and propulsion apparatuses, methods and systems”, mimics the movement of marine life to generate power without traditional blades or rotors.
Innovation Inspired by Nature
The system consists of two undulating fins connected by fin coupling modules. When water flows over the fins, they ripple, changing their angles dynamically. These angle shifts are harvested by the coupling modules to produce mechanical work. The device can power pistons, bellows, or electric generators.
Its bioinspired design avoids rotating parts, making it safer for wildlife and less prone to mechanical failure. The system is adaptable for use in underwater propulsion, energy harvesting from ocean currents, and remote water pumping.
Real-World Impact
By turning slow-moving water into useful power, this invention opens new doors in sustainable energy. It offers a practical solution for remote locations, autonomous underwater vehicles, and off-grid environmental monitoring.
