Abstract
A slip ring assembly includes a stationary element, a rotatable element rotatable relative to the stationary element, and a liquid metal contact electrically coupling the rotatable element to the stationary element. The liquid metal contact includes a metallic material having a melting temperature that is less than zero degrees Celsius and a boiling temperature that is greater than four-hundred degrees Celsius to electrically couple an electrical device fixed relative to the rotatable element to an electrical device fixed relative to the stationary element through the liquid metal contact.
Claims15
A slip ring assembly, comprising:
