AI-powered muscles made from lifelike materials perform safe actions

Researchers at the Georgia Institute of Technology have developed AI-powered artificial muscles made from lifelike, hierarchically structured flexible fibers that mimic human muscle and tendon. These soft, responsive muscles are paired with intelligent control systems that enable them to sense, adapt, and "remember" previous movements, allowing for real-time adjustment of force and flexibility. Unlike traditional rigid robots, these artificial muscles aim to produce natural, smooth, and safe motions, making them particularly suitable for applications such as stroke recovery or prosthetics, where rebuilding strength and confidence is crucial. The research, published in Materials Horizon, highlights advancements in functional materials, structural design, and manufacturing techniques that enable these muscles to execute pre-programmed movements and respond dynamically to environmental changes through sensory feedback. The team emphasizes the importance of adaptability and biocompatibility, ensuring the materials can integrate safely with the human body without triggering immune responses. Challenges remain in scalability and dynamic reprogramming, but the work represents a significant step toward prosthetics and assistive devices
