  "textContent": "Researchers at Tohoku University, working with international collaborators in France, have developed an ultrafine \"soft yarn\" actuator fiber capable of bending, contracting, and producing complex three-dimensional movements when electricity is applied. The technology offers a new pathway for building safer soft robots and body-conforming wearable devices designed to interact closely with people.",
