Korea Institute of Machinery and Materials (KIMM) researchers led by Dr. Cheol Hoon Park have developed an automated weaving system producing "fabric muscle" from 25-micrometer shape memory alloy wire. The 10-gram fabric lifts 10-15 kilograms, enabling wearable robots weighing less than 2 kilograms that reduce muscle effort by 40 percent during physical tasks and improve shoulder movement by 57 percent in clinical trials at Seoul National University Hospital, with findings pu
