Shaping the future of robotics through materials innovation

Nature Materials volume 20, pages 1582–1587 (2021)Cite this article

Subjects

New classes of functional soft materials show promise to revolutionize robotics. Now materials scientists must focus on realizing the predicted performance of these materials and developing effective and robust interfaces to integrate them into highly functional robotic systems that have a positive impact on human life.
