South Korean engineers have made a remarkable breakthrough by creating a soft, shirt-like exoskeleton designed to enhance mobility and independence for individuals with degenerative muscle conditions. This innovative device not only costs significantly less than traditional hard exoskeletons but is also lightweight, weighing under two pounds, making it an exciting advancement in robotics.

Developed by the Korea Institute of Machinery and Materials, this exoskeleton resembles a regular cotton shirt, combined with a simple nylon harness that houses the electrical components. It’s akin to wearing a set of supportive muscles, crafted from ultra-fine threads made of a special shape memory alloy. This clever design allows the material to contract and mimic the natural movement of lifting an arm, effectively reducing strain on the wearer’s muscles by 40% to 57%.

One inspiring story comes from Myung Ha-yul, a 15-year-old student living with Duchenne muscular dystrophy. Since his diagnosis in elementary school, Myung has needed assistance with daily activities. Doctors had previously cautioned him and his family that simple tasks, such as brushing his teeth or combing his hair, might become impossible as he grows older. However, during trials at Seoul National University Hospital, Myung experienced the joy of using the exoskeleton shirt and shared his excitement with the media. “It felt amazing because it was light and easy to wear, just like clothing,” he mentioned, noting how he could lift his arms with much less effort.

The shirt boasts the capability to lift up to 34 pounds on its own, and when combined with the user's own strength, it significantly restores the ability to perform basic movements and activities.

Professor Lee Woo-hyung, a rehabilitation medicine expert at the hospital, highlighted the significance of this development, stating, “The biggest achievement is that patients can put it on and take it off like clothing, while receiving active muscle support that leads to real functional improvement.”

This incredible innovation was made possible through the generous Child Cancer and Rare Disease Project, which commenced in May 2021 following a substantial 300 billion won ($204 million) donation from the family of the late Samsung chairman, Lee Kun-hee.

This advancement not only showcases the potential of modern technology but also embodies the spirit of hope and improvement in the lives of many.
