Abstract: Previous electrochemically-powered yarn muscles cannot be usefully operated between extreme negative and extreme positive potentials, since strokes during electron injection and during hole injection partially cancel because they are in the same direction. Unipolar-stroke carbon nanotube yarn muscles are described in which muscle strokes are additive between extreme negative and extreme positive potentials, and stroke increases with potential scan rate. These electrochemical artificial muscles include an electrically conducting twisted or coiled yarn and a material that dramatically shifts the potential of zero charge of the electrochemically actuated yarn.

Abstract: Data routing with a forwarding process of service data can avoid problems of offline nodes. The forwarding process for data routing can also improve the fault tolerance and service data can be quickly transmitted to a corresponding data pool. Using consensus nodes and a target data pool with routing and forwarding tables along with subtrees from a trie tree can improve the routing. Subtrees may be obtained by splitting the trie tree from a root node by using a first leaf node as a benchmark, which correspondingly represents a data pool of the consensus node. The routing and forwarding table is configured to record addresses of data pools correspondingly represented by a preset quantity of leaf nodes in a corresponding subtree.
