Abstract

Millisecond timescale charging and contraction of carbon nanotube artificial muscle is demonstrated. The mechanical power-to-mass ratio is five times higher than in human muscle, and electrical power transfer is ten times greater than observed in supercapacitors. These results show that, despite their electrochemical nature, carbon nanotube electrodes (see figure) can respond surprisingly quickly.
