6. Biomimetic Propulsion Systems
Inspired by aquatic life, biomimetric propulsion systems copy its effective movement patterns. These devices generate undulating motions like those of fish or marine mammals by means of flexible materials and sophisticated actuators. Maintaining very silent operation, the technique greatly minimizes drag and boosts propulsive efficiency. More complex applications of this technology are made possible by recent advancements in smart materials and artificial muscles; some prototypes show amazing dexterity and speed while using less energy than traditional propulsion systems.
