Soft exosuit helps people walk without bulky motors
Researchers in China have developed a lightweight, soft robotic exosuit that assists hip movement to reduce the energy required for walking. The 4.2-pound device uses artificial muscles to pull at the hips, helping users walk more efficiently.
Why it matters
This technology provides a less intrusive and more portable alternative to traditional, bulky exoskeletons, potentially aiding mobility for the elderly.
Walking through an airport or around a large store can take more energy as we get older. Researchers in China are now testing a soft robotic suit that could someday help your legs do some of that work. The experimental soft exosuit assists the hips using thin artificial muscles instead of conventional motors and gearboxes. The research, published in the peer-reviewed journal Science Advances, describes a 4.2-pound prototype that fits around the waist and thighs like a lightweight harness. In a small treadmill test, six healthy adults used an average of 13.9% less energy while the powered assistance was active. Sensors also showed that their leg muscles worked less. So, how does the soft exosuit actually work, and what still needs to improve before you could ever wear one? SELF-DRESSING CLOTHES COULD HELP OLDER ADULTS CyberGuy Live: Missed "Sick of Spam?"
