Hair-thin 'soft yarn' actuator fiber moves with electricity

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.
