Why is it important?
By synthesizing recent research and highlighting ongoing hurdles, this review emphasizes the transformative potential of DEAs, offering a comprehensive look at their current state and future impact on next-generation medical devices.
Perspectives
While the potential of DEAs in medical applications is clear, challenges remain, particularly regarding material durability, actuation voltage requirements, and integration with existing medical technologies. Future research will need to focus on addressing these challenges, particularly through advancements in material engineering, power efficiency, and the development of more sophisticated control mechanisms. Overcoming these obstacles will help unlock the full potential of DEAs, advancing their role in next-generation medical devices and contributing to improved patient outcomes.
