A research team from South Korea has achieved a remarkable breakthrough in the development of a cutting-edge artificial muscle, poised to revolutionize industries such as robotics and healthcare. This innovative artificial muscle demonstrates an extraordinary load-bearing capacity; a mere 1.25-gram sample can hoist a 5-kilogram weight in its rigid state, a feat equivalent to lifting 4,000 times its own weight. Moreover, it exhibits exceptional flexibility and stretchability, capable of extending up to 12 times its original length in a flexible state, with an impressive contraction rate of 86.4%. Its power density per unit volume is approximately 30 times greater than that of human muscle.

The artificial muscle employs a dual-crosslinking structural design, leveraging shape-memory polymer materials. It achieves seamless state switching through the synergistic interplay of chemical and physical bonds. Additionally, magnetic particles are integrated into the design, enabling remote-controlled deformation. Industry experts are of the opinion that this breakthrough transcends performance limitations, paving the way for new development avenues across multiple fields.
